This is a wonderful Art Deco glass bead necklace. The beads are opaque glass in green and tan with white seed bead spacers. At the center of the necklace is a large green melon bead with tan disk shaped beads on either side further up there are smaller green melon beads and tan bicone beads. It fastens with a brass barrel screw catch. It looks like it has been restrung (those white seed beads may be a later addition, I'm not sure) and it appears to be secure.
It is just short of 16 inches long and it is in excellent condition.
