This is a vintage Art Deco choker necklace with dangling green glass beads. The necklace is not marked and I do not know who made it. There is one large green glass bead with smaller beads on either side and beneath it. There are three dangling chains with a glass bead at the end. The necklace measures 14-1/2 inches long and the center measures 1-1/4 inches long. 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.
