This is a beautiful vintage lavaliere style necklace. It is not marked. The necklace has a pendant comprised of six blue open backed headlight rhinestones. The rhinestones are all prong set. The necklace measures 15 inches long and the pendant is 2-1/4 inches long. The necklace and pendant are in very good condition but may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
