This is a vintage double strand necklace made of light blue matte pearls and blue aurora borealis glass crystals. The necklace is not signed. Some of the pearls are an irregular shape. There is also a clear crystal spacer on either side of the blue crystals. The necklace is adjustable and measures from 18 to 21 inches long. The necklace is in good condition but may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
