This is a vintage double strand necklace made of aurora borealis crystals. The necklace is not signed and I do not know who made it. The necklace is adjustable and measures from 21 to 24 inches long. There are rhinestones on either end of the connectors holding the two strands together. The crystals have a lot of iridescence but I could not capture this in my pictures. The necklace is in very good condition but may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
