This is a vintage gold tone brooch with amethyst and clear rhinestones. The brooch is not signed and I do not know who made it. The rhinestones are prong set. The brooch measures 2-1/4 inches by 1-1/2 inches. It is in good condition but may have some minor wear to the gold tone on the back. The brooch has not been cleaned or polished. Please let me know if you have any questions. Thanks for stopping by.
