This is a combination brooch or pendant in the shape of a cocktail or martini glass. The brooch is not signed. It has blue and pink enameling on it. It also has a faux marcasite design on two portions of the glass. The brooch measures 2 inches by 1-1/2 inches. There is a loop on the back so it could be worn as a pendant. It is in very good condition with no missing enameling. The brooch may need cleaning. Please let me know if you have any questions. Thanks for stopping by.
