ART DECO AMETHYST AND ENAMEL BROOCH
This is a very unusual piece - I haven't seen any other Art Deco jewelry using translucent enamels. The design of this brooch is beautiful - a large, fine amethyst is surrounded by a radiating rainbow of translucent enamels, accented with diamonds. We don't know who made this, but it was made by a master jeweler.
