CORO DESIGN PATENTS
CORO DESIGNERS
The career of Adolf Katz, Coro’s head designer, spanned nearly 40 years. According to patent records he appears to be a remarkably talented and prolific designer, holding more jewelry design patents in his name than anyone else in the industry.  Much of Coro’s incredible business success is attributable to Katz and Coro’s diverse, beautiful and imaginative jewelry lines are evidence of his enormous talent. Whether or not he single handedly designed every piece of jewelry credited to him in design patents, as head designer he would have been responsible for selecting the designs produced by Coro’s talented teams. As such, it was Katz’s vision that defined Coro. After joining Coro in 1924 Katz became head designer and production manager in 37, VP in 48 and Executive VP in 1960. Along with Carl Rosenberger as President and Coro's dynamic sales manager, Royal Marcher, Katz defined Coro's great creative and business success. Katz’s career with Coro lasted from the 1930s through to supervising Coro’s “new” Vendome line that replaced Corocraft as Coro’s top line from the 50s through 70s.

Other designers who appear on Coro’s design patents include Gene Verecchio who produced the celebrated “Quivering Camellia” line as well as many distinctively beautiful jewels made with faux “moonstone” multi-colored cabochons. Other celebrated designers include Charles Pauzat, Oscar Placco, Robert Geissmann and many others.

A heart felt thanks to the many collectors and dealers who have contributed photos of Coro jewelry to illustrate the design patents on this site.

3. 1946 to 1949 Post WWII  (October 7, 2003)
The end of the war marked the return of the rhinestone as a prevalent feature in Coro's jewelry designs and by the end of the 40s designs became markedly lighter and simpler in style.

Coro Florals 1942 to 1945
4. Coro Florals 1942 to 1945  (October 7, 2003)
The 2nd World War had a powerful impact on the development of American costume jewelry.  Americans, for the first time, were cut off from the influences of European fasion and materials, such as quality rhinestones, became very difficult to acquire.  In late 1941 tin, nicket, zinc and copper were re-directed towards the war effort and became inaccessible to the jewelry trade.  Sterling silver substituted for the base metals and was used from 1942 into the mid 50s and metalwork, accented with enamel, lucite, faux turquoise, jade and seed pearls often became imaginative substitutes for rhinestones.

Coro Duette Patents
14. Coro Duette Patents  (October 7, 2003)
Each Coro Duette or separable brooch had a uniquely shaped Duette frame made specifically to hold the two pin clips (or fur clips)in a fixed position so that together they could be worn as a brooch. When the duette frame becomes separated from the clips it is almost impossible to know what pin clips it belongs with and the duette is lost to jewellery collectors. Single duette clips can often be found but the value of a separated clip is far lower and less desirable than a fully assembled duette.

This web page is actively seeking photos of duettes with their corresponding frames to help dealers and collectors reunite the separated Duette segments. Please sign the guestbook if you have a photo to contribute.

15 new Duette patents uploaded on April 28/06.

Coro Mexico - Unpatented
16. Coro Mexico - Unpatented  (October 7, 2003)
During WWII and until about 1950, Coro contracted Taller Borda Silversmiths, owned by Hector Aquilar, to produce jewelry out of Mexico in response to the shortage of metals in the US.  The pieces are spectacular and an interpretation of 40s style that is uniquely Mexican. This jewelry was not patented as it wasn't created by Coro's designers.

Hector Aguilar had previously worked for Spratling's "Las Delicias" before opening his own studio.

Coro History Research
Evelyn Small Rosoff (1929-1992)

Stacey Rosoff of Rifka's Treasures and member of Jewel Collect stumbled on a treasure trove of Coro history when her father-in-law, Howard Rosoff, moved into a nursing home.  Stacy always knew that her mother-in-law, who had passed away suddenly in 1992, held an important position at Cohn and Rosenberger, manufacturers of Coro jewelry.  Howard wouldn't allow anyone to move anything in the apartment so the documents, chronicling his wife's career, remained out of sight.  

Evelyn Small Rosoff had worked for Coro from approximately 1950 to 1959. She kept cards and letters and all types of meaningful memorabilia, including many documents and photos about Coro. Through this web page Stacy has generously shared these items with anyone who may have an interest in the history of vintage costume jewelry.

Stacy writes,"I was lucky enough to learn so much more about my mother-in-law through all of these treasures than in the three short years I knew her.  It was very bitter-sweet finding out all of these interesting things and realizing how much we missed her. She and I would have had this great passion to share.  As an added bonus, I was also able to learn all kinds of facts about my husband's childhood - things only a mother would remember!".
 
Stacey's shop, "Rifka's Treasures", is named in honor of her mother-in-law (her Hebrew name).

Thank-you Stacey for sharing this priceless history.

Coro Manufacturing
22. Coro Manufacturing  (October 7, 2003)
From humble beginnings in a small NYC shop Coro grew to become the largest manufacturer of costume jewelry. Coro proudly describes their manufacturing facility in Providence, RI...

"The lighting is perfect, and shining glass windows provide excellent ventilation. A large cafeteria and a parking lot are provided for the convenience of employees.  Musak is another feature and rest periods relieve the afternoon hours".

In 1951 Coro produced a History and Sales Manual in honor of the company's 50th anniversary. The photographs and quoted text on this web page are taken from this handbook, which was generously shared by Stacey Rosoff.
