Jewelry by Knoll & Pregizer. Pforzheim, Germany. 1887-1975

Knoll and Pregizer Jewelry History. KP Germany Sterling 925 935 Victorian-Edwardian-Belle Epoque-Art Deco Jewelry and Watches through Post WWII.

This website was started June 2009 and is the first and only authentic website on Knoll & Pregizer Jewelry.

I have been collecting this exquisite jewelry for over 20 years now , unfortunately compared to the size of some of my other collections this one is much smaller as it is usually hard to find. Each acquisition of a piece of Knoll & Pregizer has been a joy to acquire. "In my collector's eye, they are the Cartier of German costume jewelers." This is just a small portion to give you an idea of the quality of jewelry made by this amazing company, as I have many incredible pieces that are not on this site. Sometimes the KP punch is so small that you might not even know you have a piece. I have had pieces for a couple of years before I found the mark. Sometimes I will buy a piece of it missing stones knowing I might never be able to repair it just to have it in my collection, however over the years as my collection grew and evolved, I did indeed have several of my most special treasures repaired and restored. Each piece is handcrafted from sterling silver, using the finest paste and imitation glass stones mimicking platinum,diamonds, rubies, sapphires and emeralds, also copies of fabulous "tutti frutti/fruit salad" stones. Sometimes they will use semi-precious stone colors such as amethyst and onyx. The pieces are constructed exactly as a piece of fine jewelry would be, and I am sure the same jewelers working on real jewelry also made these exquisite imitations. My saddest loss was not being able to buy a Cartier copy of an Art Deco Egyptian Revival scarab brooch they made but I will never forget that piece. You never forget the ones that get away...and sadly several have. (I am so thrilled to report that in 2012, I am now the happy owner of this breathtaking and extremely rare and unique piece. Sometimes it can take years to obtain the jewel of your dreams. See my treasure below!)

For years it remained one of those jewelry mystery marks that remained unsolved to us American collectors. I had noticed the company name listed in the Theodor Fahrner Jewelry Book of registered German companies not as KP, but as Knoll & Preziger (misspelled) and that piqued my interest.(Just the name was listed, there was absolutely no information on the company itself). I have been a passionate collector of some of the most marvelous German art deco sterling and paste jewelry with a mystery mark of KP in a shield with the letters intersecting for years trying to discover who this mark belonged to with no avail. I tried researching the name every way possible and all I would get on occasion would be watch auctions but nothing that showed the trademark. One day as I was researching I could not believe what I found. An eBay auction from a seller in Uruguay of all places who was selling a 1953 Atlanta Post catalogue containing German jewelry and accessory companies. The seller listed the names of the companies in the auction and photos of many pages. There it was. A photo of jewelry with the KP Trademark and the company name. Buying this catalogue was one of the most important purchases I’ve ever made.(After I received it, I saw that all of the ads from the companies were in German, but the descriptions in the back of all of the items were in Spanish. The writing on the cover translated to "Journal of International Trade. Spanish Edition". Many Germans had emigrated to South America and there was a large market for their products).

In all my years of research this was probably one of my happiest and proudest moments. To be able to connect and confirm all of the information together. I am also proud to be the person who has been able to give Knoll & Pregizer the respect and admiration for posterity that it deserves, since before the publication of this website virtually nothing about this company was known. This 1953 catalogue page shown below confirms without a doubt the attribution of jewelry marked KP Sterling Germany (or KP 925 or KP 935) to Knoll & Pregizer of Pforzheim, Germany. What is fascinating is in their long history they made Victorian/Art Nouveau, the garland style jewelry popular in English Edwardian and French Belle Époque and the MOST extraordinary (and my favorite) breathtaking Art Deco jewelry. Because of the 1953 catalogue page you can see the change in their style of jewelry after WWII. Amazingly, I have discovered several patents dated from 1906 thru 1975 registered in Germany, France, the United States, and the UK.

The jewelry was ALWAYS made in Germany except for the movements to their timepieces which were Swiss. The patents approved and registered for other countries were to protect their designs/inventions that were exported as well as their trademark. Many of their later watches Post WWII were made in 14K/18K gold with diamonds and the earlier ones in sterling silver with pastes or marcasites. I've seen Swiss movements marked Deauville, Knoll & Pregizer, Goldsiegel/KP, FIG, LOTOS, A. Nicolet Watch Co., FHF, and others that mean nothing to me (this is besides the two Glycines now seen) Some are 15 Jewels, some 17 jewels. Except for one piece having Nicolet on the dial and A. Nicolet on the movement (for Armand Nicolet Co) with "Knoll & Pregizer, Sterling West Germany" INSIDE the case, or movements specifically made for them marked KP/Goldsiegel (A brand of theirs) or just KP, they made the cases and had someone make the movements for them (although the 1962 trademark registration covers movements). There is a separate trademark registration for them here in the US just for their watch business aside from the jewelry, and I have found German patents for watch crystals (such as used on the KP/Goldsiegal watch I own) in 1939 as well as 1952, and the last one in 1975 for "Watch cases with band connection for flexible bracelets" and that's in addition to other patents for jewelry mechanisms going back as far as 1906. The patents were registered in the US as early as 1912, and also to England and France, as KP was always a big exporter to those countries as well as the US and Canada...even Australia and South America. They were a full-fledged jewelry manufacturer in every sense of the word, and advertising their watches in trade magazines including a 1973 Swiss watch magazine (that states the company was over 100 years old, so that predates the 1887 registration of their KP trademark by 14 years). There are people now trying to sell art deco sterling paste watches only marked 935 on the back as Knoll & Pregizer.

The ONLY GUARANTEED AUTHENTIC WATCHES ARE MARKED KP ON THE BACK!!! I own an ASPREY art deco paste watch from 1938 and the only identification that it is Knoll & Pregizer is the KP TRADEMARK on the BACK. ******I cannot stress to you enough that ever since my website was launched in 2009 and KP has become collectible, how many people are trying to sell unsigned jewelry as Knoll & Pregizer. The ONLY GUARANTEE you are getting AUTHENTIC Knoll & Pregizer is by their REGISTERED TRADEMARK!!!******

I now know they also made jewelry in 14K/585 gold, 18K/750 gold and 9ct gold (for export to England). This site is always a work in progress and I am updating my information as I make new discoveries. No matter what the piece or when it was made, the markings are the same. The K and P are ALWAYS intersecting at the bottom as shown in the advertising and images below. The letters are ALWAYS in CAPITALS. Sometimes the shield/flower might be lightly struck but the letters will ALWAYS intersect. I have already noticed some eBay sellers trying to attribute pieces marked KP in a rectangle or K.P.(notice the periods) Sterling as Knoll & Pregizer. Or low end base metal plated jewelry with a cheap hangtag of KP in script (They don't mark with script letters and they DON'T USE HANGTAGS). *****I cannot emphasize this to you enough. The mark MUST match their registered trademark.There are some other jewelers out there that have the initials KP which are stamped on the jewelry. Be vigilant and wary because misattributions abound. It was a requirement that registered German manufacturers of precious metal items had to be stamped with the fineness mark for metal and their registered trademark as they were responsible for assaying their own jewelry, and Knoll & Pregizer made a lot of jewelry for export***** I have several exquisite pieces destined for the French market as they are marked with the swan in an oval for small silver articles imported into France. The different grades of silver fineness used were to fulfill the minimum silver requirements for export to certain countries, but the majority destined for the European market were made in 935 silver which would cover export to every country except Poland whose minimum was 940. Pieces marked Sterling or Sterling Germany were destined for the Canadian and/or US market. On certain pieces they will be marked Sterling Germany and the European silver fineness in order to be sold everywhere. Throughout my collecting and research in addition to Europe, the US and Canada, I have found pieces sold as far as Australia, South America and South Africa. England, France, Canada seems to have been their largest trading partners manufacturing jewelry for retailers such as Asprey, Fortum & Mason, Ciro (watches) and Birks in Canada

One of the reasons that Knoll & Pregizer probably fell into obscurity is because, as far as I can tell, except for trade journals and catalogues, they did absolutely no advertising in the way Theodor Fahrner did. They were not known as a "brand", except for their watches. (Someone once sent me a picture of their gorgeous LOTOS paste watch in a marked LOTOS velvet case). Their jewelry seems to have been made as private label orders for the carriage trade and sold in the finest upscale jewelry and department stores in Paris, London, New York (they had a US rep and their trademark and patents were registered here) and other major cities across the globe. Pforzheim firms (not just Knoll & Pregizer) made some of the best paste jewelry I've ever seen. I have a magnificent KP art deco necklace that I purchased in its original unsigned jewelry store box, satin lined inside and leather on the outside with gold tooling. It came from a Massachusetts estate and by the markings on the jewel I can tell it was made for the European market. This dazzling piece was probably bought on holiday in Europe in the 1920s or 1930s at a fine jewelry store...a time of unparalleled glamor and luxury (despite the Depression and the coming of WWII). It looks exactly like carved jade and diamonds and was cared for as such, by the beautiful,almost pristine condition it is in 90 years later. I believe that the best of KP jewelry was sold not just to women who couldn't have the real thing, but to many women who COULD, and considered it "travel jewelry"...copies of their real pieces that they could wear that would fool the eye, but not to be afraid to wear for fear of losing or being robbed of their real jewels. However, fine paste jewelry itself was always desirable on its own...not just as a copy of real jewels for the "have nots". Many women of discriminating taste and style wore paste jewels lavishly, and no one would be the wiser that they were not wearing Cartier or Van Cleef & Arpels. Stores such as Asprey in London sold and advertised paste jewelry, and I have a 1930s advertisement of theirs showing a page of jewels with a paste watch looking very much like my Knoll & Pregizer deco watch below, along with double clip brooches, ear clips, pendant earrings, rings and bracelets that would be undetectable to the eye. Jewelry stores like that would have sold the pieces in their own fitted cases, not identifying the jewelry as an outside manufacturer. In the US, there were companies making sterling paste jewelry such as Diamonbar by Wachenheimer Bros. in Providence, RI, and New York firms such as Fishel Nessler and Ciner. Other companies were making exquisite reproductions of fine jewelry in rhodium plated metal with the finest paste stones such as Trifari, Mazer, and DuJay as noted in 1934 and 1936 Saks Fifth Avenue ads I have where the copy would say "reproduced from a fine jeweler's piece".

Like many incredible jewelers of the past, all good things must come to an end. By what I have seen of the gold pieces I believe these were made while the company was winding down in the 1960s-1970s. Nothing is as grand or as extraordinary as their heyday up until the late 30s and the start of World War II. I do have several pieces marked West Germany that are post WWII and lovely, but I still think the pre-war pieces were the best. As with every manufacturer, they made different qualities of jewelry for different markets and price points. As I've continued to collect I've found the same models made with less fine manufacturing techniques for lower end production. Unfortunately, as the company was nearing its end in the 1970s, they made some of the most atrocious pieces I have ever seen. To see them go from the magnificence of their early days to some of the ugliest, modernist monstrosities, was very sad indeed.


KP Sterling Germany

KP Sterling (usually with a retailer or mystery mark)

KP Sterling Birks in SCRIPT or CAPS (For Birks in Canada)I need to add a caveat for these Birks pieces. ONLY if it is marked Birks WITH the KP trademark was it made by Knoll & Pregizer. Many other companies made jewelry for Birks. If it does not have the KP mark then it is NOT KP.

KP 800 (This is the lowest amount of silver, also referred to as "Coin Silver" or Continental Silver used in Europe)

KP 830

KP 925

KP 935

KP Sterling West Germany Post WWII

KP 925 or 0.925 (in a rectangle) West Germany Post WWII

KP 585 or 0.585 (in a rectangle) (14K) West Germany Post WWII

KP 750 or 0.750(18K) West Germany Post WWII

KP 9ct for export to England

KP Metal/Rhodiant- I believe this jewelry to be c.1960 or later and made for the lower end market. Rhodiant is some type of rhodium-like plating although my research turns up very little about it. I have only seen 3 pieces marked as such--a paste lapel watch and a necklace and earring set with no other silver fineness mark...which regardless of how it tests I believe to be nothing more than plated metal. I know from trademark applications to the US in 1962 for their jewelry and watches, they covered precious metals (gold/silver) and "their alloys". Every piece I have from pre-WWII and for many pieces after are all precious metals except for my 1950s earrings where the inside of the clip mechanism on the earring is marked "metal" and the outside "sterling", obviously to cut costs.

*****Knoll & Pregizer KP REPRODUCTION ALERT*****

I have added a pair of earrings to the album that have been making the rounds on eBay as recently as September 2011. (Now in 2012 I have seen at least 15 pairs of these sold this year alone--still showing up in 2018)). I bought my pair shown below about 10 years ago on eBay knowing full well they were reproductions and not authentic deco paste, but I never took any notice of the KP mark. My first pair of art deco paste reproduction earrings were, in fact, purchased in person, by me, at the Chelsea Antiques Fair in London 16 years ago while on vacation. At the time I knew little about paste jewelry and nothing of reproductions and believed them to be completely authentic, until I saw my English "antique" earrings start to turn up by the boatload a few years later on eBay sold by a host of different sellers. Very expensive but important lesson learned. Authentic period earrings were not made in huge multiples in different colors. The same earrings could not possibly be sold by a multitude of sellers at the same time and be original. This has nothing to do specifically with KP, just reproductions in general, so from my experience I know this has been going on for at least that amount of time, probably longer. A friend alerted me to a pair recently on eBay and I said "I have those" and pulled my exact pair out. Sure enough, there it was. The KP trademark. Apparently these reproductions were made from an authentic pair of KP earrings that were used to make the mold. I know they are different earrings made at different times because they have different surmounts from mine. The ones I saw are brand new, and mine have the patina of age, so this means they have been making this earring for at least 10 years. Usually KP put their trademarks on the screwback fitting (HINT: Authentic early KP earrings were mostly made as screwbacks, not pierced,because that was not the style at the time. Many KP earrings will forever remain unidentified because of conversion to pierced earrings/posts and the removal of the KP trademark on the fitting) and not the jewel itself, but I do have an authentic pair of KP earrings where they are marked on the back of the earring like these. The earring I am showing is the only reproduction piece I have seen thus far. I am fairly certain that at that time years ago when the original earring was copied, the mark meant nothing to whomever manufactured them, they just liked the style. I have not seen mention of the KP mark in the auctions yet, but it is only a matter of time before someone tries to sell these as authentic. See my description below to know what to look for.

Founded in 1887 by Theodor Eberhard Friedrich Knoll and Friedrich Pregizer. Friedrich Pregizer left the company in 1907 and was replaced by Carl Knoll. Registered in 1887 (Theodor Fahrner by Schmundt-Weber-Becker book page 68) misspelled. Along with jewelry, they made watches signed Goldsiegel(Gold Seal) registered in 1938, KAPE registered in 1935 and 1938 and also signed LOTOS (registration date c.1940). I have a very early and elegant art deco paste watch that has no name on it except SWISS on the front of the face and the KP mark on the back along with a registration number. I've recently discovered a watch they made marked NICOLET for the Armand Nicolet Co. from Switzerland post WWII. Other marks on their watch faces include LOTOS, KAPE, KP, Corundo, Knoll & Pregizer,or the names of retailers or companies where KP manufactured the watch cases for them. Sometimes, but not always, the movements themselves will be marked KP. They probably had a Swiss company manufacture those movements for them. One of my most interesting purchases was of a wonderful 14K Man's Military Watch. In 1971 Knoll & Pregizer won the prestigious Golden Rose of Baden-Baden award for excellence for their watch model named "Evening Star". This award was considered the "Oscar" to German watch manufacturers. (found in the publication "Baden-Württemberg" in Google Books). I have found many patents of theirs in my research including the earliest ear clip finding patented in Germany in 1906 and later registered here in the US in 1912. In contrast, the first American company to patent an ear clip was Ballou in 1934 so they were way ahead of their time.

KNOLL & PREGIZER, of 16, Goethestrasse, Pforzheim, Germany 455 Zugang 1992-53 Nr. 372 Post WWII Archive Records that show they were registered as a business from 1948-1973 (many of the business registration records for German jewelers were destroyed during the war hence the date of 1948 for KP) however I have found a patent for a watch crystal as late as 1975. This, along with the 1887 date of registration as a company from the Theodor Fahrner book, patent info, and other trade publications confirms that Knoll & Pregizer were in business from 1887 thru AT LEAST 1975. Although they were open during WWII, from private research that I own, I know that in 1942 they were "overflowing with orders for men's and women's golden wristwatches and at the moment we see no way to deliver them". During WWII,on November 9, 1944, the large office building where Knoll & Pregizer was located in Goethestrasse sustained tremendous damage when hit by a heavy bomb. "Bombing Germany: The Final Phase" by Tony Redding published in 2015. On February 23 1945 the city of Pforzheim suffered its largest and most devastating air attack by the RAF with nearly 2/3 of the city and a third of the population destroyed. Because the town was the jewelry and watch center of Germany, the Allies thought they were producing precision instruments for the German war effort. Pforzheim records date Knoll & Pregizer (and many other companies) from 1948 onward because many of the previous records were lost. Anything regarding their jewelry, watches or factory during WWII is sketchy as I don't believe they were allowed to export anything out of Germany past 1939.Please see some U.S. Trademark information for Knoll & Pregizer that I found recently in the United States that was registered in 1962/1963 by Walter Knoll who ran the company during those years for costume and precious jewelry as well as watches. You can see these documents at at the end of the album. The trademark expired in 1987, but since I have not found any information about the company since 1975, I am "assuming" they were given a 25 year US trademark. Will update if I find any further information.

The company was run from 1969 until 1972 by Lutz Stavenhagen, who married Christine, the stepdaughter of the former managing director of Knoll & Pregizer jewelry and watch factories, in 1965. Mr. Stavenhagen, was a German politician (Minister of State at the Chancellery and Member of Parliament) from 1972 until his death in 1992. His wife Christine died in 2015.

I found a listing from the 1970s of Der Deutsch-Amerikaner von heute:Deutsch-Amerikanisches Adressbuch fur due-by Stefan Deubel Page 383: US Rep: Grosse Jewels 303 Fifth Avenue NY, NY. Knoll & Pregizer, Pforzheim Watches & Jewelry Pforzheim, Germany had hundreds of jewelry manufacturers on par with Providence, RI here in the US. I have many pieces of jewelry just marked Sterling Germany, but **UNLESS THE PIECE IS MARKED KP, ONE CAN'T CONFIRM IT WAS MADE BY KNOLL & PREGIZER**. THIS IS IMPORTANT TO NOTE AS THEY WERE DILIGENT ABOUT MARKING THEIR JEWELRY AS REQUIRED BY GERMAN LAW.

Per his great-great grandson Thomas Wolfgang Maguire on 8-12-09 the family tree is: Theodor Eberhard Friedrich Knoll ( 1851-1928) (Great-Great-Grandfather) ---- Theodor Knoll(Great-Grandfather) (1881-1961)----- Margarete Nestlen nee Knoll (1914-1984) ---- Margrit W. Maguire nee Nestlen (1943) --- Thomas Wolfgang Maguire (1981) His mother Margrit is the granddaughter of Theodor Knoll.

VERY EXCITING NEWS PER GREAT-GRANDSON THOMAS WOLFGANG MAGUIRE ON 9-10-09: "The History of Knoll & Pregizer according to the Archives in Pforzheim and translated from German." (This is exactly as it was translated, I have not made any grammatical corrections) "The Knoll Family originates from Schwäbisch Gmünd, there they had a small shop inside their home to make Jewelry for the Areas Jewelry Stores. After Theodor Eberhard Friedrich Knoll learned to be Goldsmith in the Home Business of His Father and learned at a Technical School did he go to The Military. After he left the Military in 1877 did he take up a position as a Apprentice in a Fine Pforzheim Business, after two years he made himself independent and founded a small business in Pforzheim. In 1882 did he take into the company The Merchant and Traveling Imitation Jeweler Friedrich Pregizer. The Company now was run under the Name of Knoll & Pregizer. The offer was extended to the production of Imitation products using Fine Pour Technique. In the future the company was able to begin thanks to a little competitive pressure to increase their sales steady and even train their own apprentices. There was establishing or further branches and others in Nagold. In 1907 Pregizer resigned from the business. After the two eldest sons, Carl and Theodor of merchants had completed training in Pforzheim stores, They picked up their father as an employee and left them after 1914, the sole managing director. From the effects of World War I. The production activity (could be maintained only in very restriction. The Nagold branches had to be closed.) Recovering the company after the war, again due to high demand, was relatively quickly. Carl Knoll, the eldest son and later on the city council had received since 1906 with the departure of Frederick Pregizer transferred the commercial management of the business. He married about 1908 Margarete nee Nestlen with which he had three children, Ilse (born 10.12.1908), Marianne and Walter (both born on 27.5.1911) had. The latter subsequently took over the lead. Erich Keller, son of Ilse Knoll first marriage, was transferred in 1957 by the participation in the business. Both Life Stories which are steepened the above information is taken to give a great insight into the families and Company history, especially from the Pforzheim Foundation 1879 to 1958. In addition, the city archives has in its files Commercial Papers (Knoll & Pregizer, jewelry and watches factory, manufacture of watches and jewelry, Walter Knoll; Friedenstr 62; Goethe Strasse 16."

All of the pieces and pictures are from my collection except where noted. Many thanks to my dear friend and colleague Dr. Kristin Rheinwald in Germany who so patiently helped me translate and navigate these German archives. She has been invaluable to me and a wonderful friend. I would also like to thank the very gracious keeper of the Knoll Family History, Thomas Wolfgang Maguire, great-great grandson and great-grandson of both TEF Knoll & T. Knoll for being so generous sharing his time and family history and wonderful photographs. -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

It's quite long and breaks apart into two bracelets of which I have not figured out how to do and probably never will. Look how exquisite the pendant is, and the entire necklace chain and top part of the pendant is made out of baguettes.

This is one of the best pieces of KP I have and will treasure not just for it's beauty, but for the fact that it came from such a wonderful friend. c.1925

This is a closeup of the most unusual of the marks on the necklace. It is the initials EG on either side of the Jewish star.  
Several KP pieces I own have this mark along with another country's import marks so this may be the sponsor's mark.
The fact that this piece is marked both 935 (European sterling fineness mark) and STERLING GERMANY means this could be exported to any European country or the US/Canada or other countries which would have required the STERLING mark for fineness and GERMANY for country of origin.

Jewish Star with EG on either side-this was  a sponsor's mark that was required when KP exported a piece of jewelry. The sponsor would re-assay the piece to confirm metal content when it arrived in their country also for duties and taxes.
The last mark is difficult to decipher but it is a swan, the import mark for France where it was  shipped to.

You can see close up even after so many years how wonderful the millegrain mounting is with  brilliant, masterfully bead set stones just like real diamonds would be. All of this was hand done.

Knoll & Pregizer KP Art Deco Paste  Bracelet c1930s
This is typical 1930s Hollywood glamour. Construction of heavy, solid sterling silver with stones set in open back mounts, each of the 6 circular panels contains 21 prong set unfoiled emerald pastes in a bow tie motif surrounded by bead set white pastes and channel set baguettes set east and west alternating with oblong pavé set connector links. Hidden safety clasp. Marked Sterling Germany KP and the number 27 on the tongue of the clasp. Every stone is perfect. This is an exact imitation of a fine emerald and diamond platinum art deco bracelet, no one would know the difference. A superb example of Knoll & Pregizer at its best.

1920s Knoll & Pregizer  KP Sterling Germany Deco Paste Clip
This beautiful use of color and style of this clip has an Indian influence so prevalent in art deco jewelry. A mixture of calibré-cut,baguette,round and even a triangular stone. Bullet nose emerald colored cabochons on either side of the top. Wonderful workmanship and extremely high quality.

Similar clip also by KP in European Designer Jewelry by Ginger Moro in her German section page 127. The reference is only to KP on the clip. There was no knowledge of Knoll & Pregizer at that time.

I've since had this restored by a master fine jeweler who cut stones to match the calibré and baguette cut ruby pastes that were missing. This is not an easy repair since they are all hand-set stones exactly like in fine jewelry, not glued in. Over the years I found a 2nd one in perfect condition so now I have a pair.

c.1920s Knoll & Pregizer KP Deco Dress Clip Back
Marked Sterling Germany and Makers Marks KP.  This clip mechanism is beautiful.

From the back, you can see this piece is constructed with both closed and open backed settings. Know that KP only used silver foil backed clear pastes to match the metal. The colored stones are always unfoiled.

If you ever see gold foiled ones in these it means the piece was repaired and they are replacements...and most likely glued in. KP did not use glue.

When you have a repair or restoration done by an expert you should not notice it.

Birks Knoll & Pregizer KP Sterling Paste Tree Back
Marked Birks in script possibly for Birks-Dingwall. There is some conflict between dating and usage of the Birks signature in script and the one in CAPS. Henry Birk & Sons absorbed many companies over the years in Canada, and they used different fonts in their ads and catalogues (sometimes even during the same year) strikings on jewelry, and also depending on whether something was an article of jewelry or for their silverware and hollowware. 1933 is when Birks-Dingwall merged.The style and the scale of the jewelry says to me earlier as does the non-rhodium plating, but I will leave Birks-Dingwall as the connection until I find out otherwise.

Please remember that unless these signed Birks pieces are ALSO marked with the KP trademark then there is no way to know if they were made by Knoll & Pregizer.

I have KP jewelry using either the Birks script or CAPS marks.

There were several German suppliers making jewelry for Birks. Knoll & Pregizer was one of many, so the on...

KP Makers Mark

This was the first time I ever saw Birks in script. I was fortunate while researching to find the Birks-Dingwall mark in an ad that confirmed the script signature, however, realize German jewelry stopped being exported to the US and Canada in 1939 due to the war, and resumed after WWII.

Until I can find out anything more accurate, I am going to "assume" these Birks in script pieces were for the Birks-Dingwall stores. My research is still continuing. I dont't think at this point in time the signature can be used for dating with any kind of accuracy.

Birks is considered the "Tiffany of Canada" and a very high end retailer.

They imported a lot of sterling paste and marcasite jewelry from Germany for their stores.

Birks Dingwall mark
This is the mark for Birks Dingwall that I found in a 1940 ad.  It matches the Birks in script on the back of my little tree brooch and the only Birks  script mark found so far on KP jewelry. I believe my tree is certainly before 1940. Nothing was being exported out of Germany past 1939 due to the war.

Per the fantastic sleuthing of my dear friend Meg Andrews below, she has confirmed D. R. Dingwall was taken over by Henry Birks & Sons in 1933 and renamed Birks-Dingwall.


I also found in the Winnepeg Free Press dated 10-17-1935 the obituary for D.W. Dingwall (His father was D.R.Dingwall the original founder). "Two years ago it merged with Henry Birks and sons, being the President of Birks-Dingwall Ltd. at the time of his death". This confirms the 1933 merger date of the two companies.

Knoll & Pregizer KP Germany Sterling PasteDouble Clip Brooch
c.1930. Sterling silver. This is two dress clips attached to a frame and worn as a brooch. The stones were yellow and dull in horrible condition but they were in open back settings. I soaked it in a bath of vinegar and salt removing all the foil. You would never know this was not platinum and diamonds. I love the mixture of the geometric cuts of stones. Double clip brooches were made by practically every jeweler in the 1930s up to the 1950s whether in real or costume.

If the stones are in CLOSED back settings and they are yellow or greenish, there is NO way to clean them regardless of what a dealer tells you. Yellow,dull stones means there is foil damage and the only fix is to have the item re-stoned or live with it. Since these vintage stones are not made anymore and are of a different cut than a modern rhinestone,I would think very carefully about spending a lot of money for a piece that is not in great condition. Yellow is damage and decreases the value of the piece.

This now resides (as it should) in the collection of Margrit Maguire and her son Thomas Wolfgang Maguire. The granddaughter and great-grandson of Theodor Knoll.

Ironically, a couple of years after sending this to Thomas and his mom, I found another one of these but with a "C" clasp, marked only 935 KP, mine were also missing the ruby eyes (they are so tiny) This tells me that Knoll & Pregizer repeated styles over the years, as the one with the "C" clasp that I now own would have been  earlier than the one in the photo. I have since seen multiples of several of their novelty type pins also made years apart.

On the screwback it is marked Germany Sterling 935 KP and a letter P. The letters P & M appear on several different jewels I own and have no idea what they mean. Because of the hallmarks, these were able to be sold in Europe or exported to the US and Canada.

A caveat. If you hate screwbacks (which I do) and ever desire to have your earrings converted to pierced (which I have) I BEG of you, get the screwback fittings back from the jeweler and keep them in the same box with the earrings and a a note that you had them replaced. An expert jeweler can always put the screwback on. More KP earrings have probably been lost to posterity due to conversions. The fitting is where 95% of the time the jewel is marked with metal content and makers mark...rarely on the jewel itself. Authentic earrings from this time frame whether fine jewelry or faux were made with screwback fittings. Pierced went out of fashion, especially with long hanging heavy deco earrings.

One thing to note, Knoll & Pregizer remade many models of their jewelry after WWII. I have a brooch that was made and hallmarked for London in the 1960s that utilized some of the elements of this bracelet (not on this site) so you can't always go by a "style" of jewelry to date it. I also have an exact bracelet that was originally made in the 1920s-1930s that was remade in the 1960s post WWII that I can date due to the markings and "West Germany" on it. The only difference is the 1930s pieces was 935 silver, and my later one was marked 0.925 in a rectangle. Everything else was exactly the same.

This piece came to me through my friend Christia and shows how imparting knowledge to each other in the world of research is so important. Knoll & Pregizer is known as a costume jewelry company. Their ads even say "Imitation Jewels". In a Post WWII German record I found a listing for KP as "Goldschmuck"-Fine Jewelers (meaning they worked in at least the minimum of 8K gold as well as making imitation jewelry in sterling.) Until I had seen this piece, the only gold jewelry I knew of was their watches. However, I found the registered KP trademark in the US in 1962 as "sellers of precious and imitation jewelry", so the 60s must be when they began making this type of jewelry. They probably decided to go into the fine jew...

Knoll & Pregizer KP 14K Violet Diamond Basket Brooch
The back of the brooch. German companies used the trombone safety clasps on occasion which is almost always considered a characteristic of French jewelry, although since I have now seen many similar KP flower brooches of for sale,also using ordinary regular rolling clasps as well, they just probably used whatever pin was handy. And I have seen other German companies used the trombone clasp, it proves it is not unique to KP.   These pins are not rare. I have seen at least 5 of them so far since posting this piece. Where there's five (and earrings) trust me, there are many, many more out there.

Since it is marked West Germany and because of the motif and that is was made in gold with real stones, I think this dates the piece to the 1960s-1970s,towards the end of their production to keep them afloat.  This one has subsequently been sold.

The arabic numerals and hands are blue enamel and the white face has no name.  The winding stem has a faux paste sapphire cabochon. This is a beautiful example of a sterling and paste watch from the 1920s. The missing stone has been replaced. The bands at this point in time were very small. 6" long.

This watch is part of the exhibit "Finer Things" at Stan Hywet Hall & Gardens, April-October 2012 in Akron, Ohio.

1920s Knoll & Pregizer Sterling Deco Paste Watch
One of the rarest pieces to find of Knoll & Pregizer if you are lucky, are their early Art Deco 935 sterling paste watches. While their later production of mens and ladies watches wasn't exceptionally interesting, this one is gorgeous, mimicking the style of platinum and diamond watches made by Cartier. The face has no name, but is marked KP on the back of the watch case and number 18606 which indicates early production. All of the pastes are bead set by hand. Arabic numerals and hands are blue enamel as well as the border around the rectangular face for the minutes. The case itself has a beautiful engraved design around the perimeter, as well as a faux sapphire cabochon on the stem. Swiss Made movement of 15 jewels. The watch case was Made in Germany.

1920s-1930s Knoll & Pregizer Sterling Deco Paste Watch
Marked Swiss on the bottom of the face under the numeral 6 and a double enamel border around the numbers with hash marks for minutes. Some of the stones have darkened but it's in beautiful condition for a piece that is probably at least 90 years old. The rectangular case has beautiful etched work around the perimeter of the case, and out of the several I now have, this is the only one with the faux sapphire cabochon on the winding stem that I just love.

c.1920s Knoll & Pregizer Sterling Deco Paste Watch
The back of the watch is marked KP within the flower and numbered 18608 which is a very early number. This is probably one of the earliest watches they made as noted by not only the early number, but the striking of the mark which is small and a little different than their later pieces.

As far as dating, I was given to publish a beautiful watch (last two pictures) of a sterling and marcasite piece serial number 19258 from 1938. So since I don't know exactly the range of dates, it's possible this piece is from the 1930s as well. As always circa dating is not definitive, and I don't know if there were different serial numbers used on their branded watches (Lotos, Goldsiegal, etc) and their unbranded watches.

Knoll & Pregizer Goldsiegel Sterling Paste Watch
Beautiful Goldsiegel (Gold Seal)sterling and paste watch. Sterling expandable band set with pastes that have darkened or slightly yellowed and two safety catches.It looks like there is an extra extender link.  This has a loop for a safety chain which is now gone. Black enamel face. Silver numerals and hash marks for the minutes. There is no brand name on the front of the watch. The square face has beautiful engraving around the perimeter of the watch case.

Goldsiegel (Gold Seal) watches are a trademark of Knoll & Pregizer and were registered July 23, 1938. Although the numerical marking would suggest an earlier date,by the styling and the patented face it is from the 1950s.  It is possible the numerical markings were different for Goldsiegel and Lotos brands.

Knoll & Pregizer Goldsiegel Watch Movement
This is what the movements of these watches look like. I can see a fair amount of rust and it's been over wound so it's not working and is not repairable. It is marked Swiss Made. KP trademark. 15 Jewels. Goldsiegel(KP's brand) LXA.  There was probably a Swiss watch company that manufactured the movement for Knoll & Pregizer as can be seen by the KP trademark and their Goldsiegel brand name. The rubies are synthetic. Thank you to my dear friend Carolyn Sunday of www.sundayandsunday.com for her guidance and information.

Knoll & Pregizer Prince of Wales Feather Paste Pin
This is a delightful brooch, small in scale, 1 " by 1 1/4". High grade sterling silver with bezel set pastes. Marked 935 KP.

Done in the shape of Prince of Wales feathers which is the heraldic badge of the Prince of Wales of England. The real Prince of Wales feathers would have a crown at the bottom holding the 3 feathers together, but it's such a lovely motif. This is a sweet type of (at the time) inexpensive novelty pin that KP made a lot of. The pastes do not fill up the entire design,those little bumps at the bottom give the look of stones without having to set them, so it was cheaper to manufacture.

Knoll & Pregizer Early Deco Paste Pin
An absolutely exquisite, small and very fine brooch pin by Knoll & Pregizer. From the art deco era but almost Edwardian in style. It has an emerald cut faceted glass faux sapphire set open back in the center surrounded by 10 large bead set clear pastes bordered by tiny bead set pastes with millegrain around the edges all set in heavy 935 sterling silver. This is a weighty piece for something so small in scale. You would swear these are real diamonds and platinum. I have never seen pastes of this age with so much fire and brilliance. My scan could not even capture the beauty of it. The sapphire color is quite deep and the scratches are only visible with a loupe and obviously enlarged by the scanner. Measures 1" long and and 3/4" wide. Marked 935 KP.

Knoll & Pregizer Set c.1950s
Here you can see the jewelry has the same feel as the 1953 ad shown in #1. By this time I think their jewelry is starting to wind down a bit. This is very typical of 1950s white "diamond" jewelry. The earrings are clip backs but the clipback mechanism is not entirely made of sterling. Inside it is marked "metal", probably to keep costs down. The large stones are open back in prong settings but the other stones are channel or bead set. Still lovely, but the jewelry is becoming a little more pedestrian. Marked Sterling West Germany KP. This particular set came from Australia, so their jewelry was probably exported far and wide.

Knoll & Pregizer KP Earrings Reproduction Alert
FAKE FAKE FAKE!! It's now 2018 and these repros are still showing up on not only ebay, but now Ruby lane as well as 1st Dibs. I believe the maker is the same.I have contacted them and they have done nothing.

I have seen at least 30 pairs if not more over the past year 2013. They are all coming from sellers in England. Please be careful. They are contemporary repros of Knoll & Pregizer and not authentic art deco. Marked KP 925 and SIL in an oval cartouche with 9 ct gold shepherd hooks. I bought these earrings on eBay c.2000 knowing they were reproductions although the seller did not--giving them the benefit of the doubt(I own at least 10 pairs of different styles all purchased over the years from the UK. These are the only paste repros I've seen with a makers mark). I never checked the back because usually they never have markings other than SIL (for Silver) or 925. I looked at the pictures in the auction then pulled out my ten year old pair of earrings and there it was....

Knoll & Pregizer KP Earrings Reproduction
The SIL in the oval cartouche was added to the mold. The 925 KP marks are from the original earrings from which the mold was made.  Modern cut rhinestones are sloppily GLUED into the settings and don't even fit the cups properly. Many times you will see the traces of glue under a loupe. The originals would have been hand bead or bezel set like real diamonds. The KP punch is not crisp because who knows how many pairs of these have been spit out from the same mold over the years. Despite the bad lighting, mine show the patina of ten years worth of age. That in itself is a problem because as these repros age, they look more authentically old,especially if you don't know what to look for. The ones I have seen recently are bright and shiny and new.

Knoll & Pregizer KP Earrings Reproduction
Authentic antique earrings do NOT use SIL in a cartouche, especially since the original earrings that these were copied from were German, made by Knoll & Pregizer (hence their hallmark on the bottom) and the silver fineness of 925.  This is as close as I could get to clear pics of the marks. This is the characteristic intersecting KP in the flower/shield but the earrings themselves are crude and poorly finished and not like fine KP quality of the period.

As an avid collector of European and American paste jewelry,I know reproductions WERE made to deceive and as a novice I paid dearly ,but KP was barely known 10 years ago, and it's just an unfortunate coincidence that these PARTICULAR earrings were made from a signed piece whose mark is now collectible. Due to the vast amount of repro paste jewelry  that has flooded the market over the years, knowledgeable collectors have become wiser.   However, who knows if at some...

Knoll & Pregizer Trademark USA 1962

This expired in 1987. Since I have no proof of anything past 1975 being made/invented or sold by the company, I am "assuming" that they held the rights for 25 years until 1987, at which time the trademark was dead.

Asprey Paste Ad 1930s
Even fine jeweler Asprey's in London sold paste jewelry in the 1930s. My Knoll & Pregizer KP Paste watch above a few rows is very similar to the watch featured on the top. Magnificently made sterling and paste jewelry was a viable alternative to real jewelry in the 1930s when even people of means had economic hardships and the coming war in Europe. The dating of 1930s is assured by the "clip on earrings" which were invented as styles of earrings changed and the double clip brooches that were especially prevalent during that time frame.

"Esclave" (bangle/cuff) watch in white gold with brilliants and colors. (Citrine and diamond bangle watch with colored crystal).

Charming pair of 935 sterling silver and 9 ct. gold paste monkeys with green paste eyes and genuine pearls on each side of the barbell.

This is another example of an early KP marked 1920s-1930s. The STERLING GERMANY denotes this was made for export to the US Or Canada. STERLING would have to be minimum 925 silver, and Germany was needed to be stamped to show country of origin. This all had to do with taxes and tariffs and requirements for each country of export. When you see only the numerical silver fineness mark and KP it was most likely made for sale in Europe. However, some pieces have a numerical silver fineness as well as STERLING GERMANY written and those could be shipped anywhere.

It is usually marked in a rectangle with a decimal point such as 0.925 or in the case of this 14K watch 0.585 (which stands for 14K which is also marked here probably for export) and again, that very crisp KP mark with the clear outline of the flower and the "o" on the bottom.

Have a spider swinging monkey brooch, looking to sell, any interest?

I am cleaning a lot of stuff out of my house. In a box of junk there was a rhinestone covered lion pendant. On the back it is stamped KP. I was looking for similar items on the internet and found your site.  I cannot find a picture of another item like the one I have, but the way it is constructed looks very similar to other Knoll and Pregizer pieces. I was wondering how to find out and if so, how to sell it.

I'm glad I found this site. I have an interesting and quite large pin brooch that is definitely Knoll & Pregizer, it is rectangular and has red and clear paste glass. I'd love to have you look at it, Robin, since you'd know way more about it than I. Please feel free to email me. Regards, Gary Palonis

I have just found in my brooch collection a small silver brooch with beautiful White stones and the Hall Mark 935 KP.. I was so excited to find your site, There is a similar brooch, which is a tree in a pot. But mine is a pretty spray of leaves consisting of round and baguette cut stones.The date 1953 is about right, as I believe it was a wedding present for my mother on her wedding day.It's a shame I cannot add a photo for you to see.
Thank you for sharing your knowledge of all things pretty.

Hi Robin
I have just come across your excellent informative site and was wondering if you could help me with a KP ladies silver and paste cocktail watch that I have just inherited.
On the back of case is marked 816 with KP. There is no name on the face of the watch. The unusual part is that the whole face and movement section is hinged but cannot get the back off to see if there are any clues.
Thank you
Best regards Eddie

Thank you for the great source of information. Do you know if Knoll & Pregizer produced a version of the Iron Cross during the First World war? I have a WW1 Iron Cross (Second Class) Cased with the stamp of KP on the ribbon ring.

I have a couple of piecesleft to me in my late aunts collection including a beautiful peacocks feather.  Do you know how I could go about having a value put on these pieces.  Your help would be greatly appreciated

I enjoyed reading about the history of this company!   It may have brought me one step closer to finding my roots in Germany.   All history of where my grandfather grew up and any family relations he left when he came to the US is unknown.  Thank you for doing such extensive research!   Now I need to find out what happened to F Pregizer after he left the partnership....

robin, please contact me I have a beautiful sterling and gold enameled ball watch necklace.  I would like to send you pictures.  Just not sure of the preferred method.  I had it in a glass case with a not for sale sign on it. But needing info on this brand /watch.  He asked what I would take for the watch I said not for sale he insisted i said not for sale.  Then from way out in left field he offered me. $500.  I am curious to know more about it (no I did not sell it)

I have a brooch 935 very similar to your divided brooch left to me by my grandmother who must have owned this in the 1940's before I was born. It has one oblong stone missing. If I insured it could you give me an idea of value please.

I have been the proud owner of an Asprey ladies 'dress watch' for many years (I have collected an eclectic mix of jewellery for many-a-long year) but which I realised was 'something different'.
Your website has at last enlightened me as to the history of this sweet little piece of art and I have had great pleasure in reading through your very informative and totally enjoyable 'site' - for which I thank you.
I am tempted to put this item on eBay at some time in the near future since I have been given an ultimatum by my wife to either de-stock or de-vorce!!
Perhaps you would like me to let you know when I do this, so that you will be able to make a bid if it is of interest to you?
In the meantime let me thank you again for all the fascinating information you have gathered together on this intriguing subject.
Kind regards,

Thank you so much for the history and pics of your collections. Often it is so difficult to get good , not to mention free information online.  May you continue to find and enjoy these beautiful pieces.

Hi, Robin.  Is it possible that there was still a factory in Schwabisch Gmund in the early 1960's where people could order jewelry of their own design?  We were stationed nearby in Goeppingen and my mother had a three strand lead crystal bead necklace commissioned somewhere in S-G, which I have now and I'm trying to find its origin.  (I was at Stan Hywet last October and toured the jewelry collection.  Very impressive!)  Thanks for your help!  Sonnie B

thanks for all the history. i was out at a casino tonight and steped on something, a rock and next to it were three others and a bracelet... junk ? KP in a shild and a P next to that with 935 above on the clasp. yes the KP intersect just as what you have on your fine examples. lots of paste diamonds and fine workmanship.
