This is a vintage antiqued gold tone double circle brooch with faux turquoise cabachons and faux pearls. The brooch is not signed and I do not know who made it. The brooch measures 1-1/4 inches by 7/8 of an inch. It is in very good condition and appears to have been gently worn, however, it may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
