This is an Art Deco rhinestone necklace. It is has bezel set amethyst colored rhinestones. The setting appears to be either brass or gold washed metal. It is not signed and I do not know who made it. It has one large square stone with two drops and smaller square stones dangling from it. The necklace has individually set amethysts which are connected on the back from the clasp to the center stone. The choker measures 15 inches from end to end. It is in good condition but may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
