This is a vintage double strand necklace. It is not signed. The necklace is comprised of very unique black and green art glass beads. There are also black faceted glass beads and tiny gold tone spacer beads. The necklace is adjustable and measures 19 inches long. The necklace is in good condition but a few of the spacer beads have wear to the gold tone. The necklace may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
