This is a vintage brooch with faux turquoise cabachon in the center. The glass cabachon is surrounded by amethyst rhinestones. The brooch also has dangling amethyst crystals. The brooch is not marked. The setting looks like either brass or gold washed metal. The brooch measures 2-1/8 inches long and 1-1/4 inches wide. The brooch is in very good condition but may have an age patina and need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
