This is a vintage silver tone necklace with three rhinestone rondelle beads. The necklace is not marked and I do not know who made it. The rhinestones on the beads are all prong set. The necklace measures 21 inches long and the beads are 8 mm. The necklace is in very good condition and there are no missing or darkened rhinestones. It may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
