This is a lovely vintage Art Deco necklace with a faceted blue glass briolette drop. It has small faceted blue glass beads grouped with gold colored melon beads and it is suspended from a paperclip chain. It fastens with a barrel screw type catch.
It measures 18 inches (wearable length) and the drop is an additional 1 1/2 inches. It is in very good condition. There are some tiny fleabite chips to the drop and some darkening of the finish on the chain.
