When we think of Mosaic jewelry we think of basically three types: Mosaic, Micromosaic and Pietra Dura. They are all similar yet different. Let's explore the similarities and the differences.
1. Mosaics=A piece of jewelry with countless small pieces of multicolored glass tiles or tesserae which are inlaid flush to create a beautiful design.
2. Micromosaic=Similar to mosaic but the difference is the glass tiles or tessarae are very, very small,using thousands of the tiny tiles which are painstakingly hand assembled and placed into a pattern,with a final step of waxing and polishing, and the finished product is much smoother or finer in appearance than the regular mosaic, and it almost appears as a fluid picture with no spaces visible.
3. Pietra Dura=(Italian) Literally, hard stone. The term (although a singular form) refers to the various hardstones (e.g. chalcedony, agate, jasper, lapis lazuli) used in flat slices in the type of mosaic produced in the Florence during the Renaissance and continuing until today, and is sometimes applied to an example of the work. Generally the background is a darker color to offset the object being depicted.

Measures 1-1/2" x 1-1/4" x 3/8" thick. There is a thin internal bezel under which the glass is seated made of gilt brass for strength and rigidity.

22 Micromosaic of a spaniel and duck C. 1820-1830's A superb micromosaic of a water spaniel flushing a duck from the reeds. Set in a 18K gold frame, the pin is 2 1/2" by 2" (the black glass and mosaic section is 2" x 1 3/4". The tiles are curved in order to create the fluid lines in the dog's fur and the reeds.
23 Floral micromosaic and millefiori brooch in blue glass, 1850's? Millefiori (literally, 'a thousand flowers') is the method in which different colored glasses were fused together to create a single cane with the same pattern throughout. The canes or threads of glass were arranged vertically, side by side, in the desired pattern, heated until they fused, then pressed together to remove air from between the threads. The resulting cane was pulled to the required thinness and sliced to produce slivers of uniform design.
