This is a very nice vintage Art Deco necklace in sterling silver set with cobalt blue 'gumdrop' or 'sugarloaf' stones. The silver has a gold wash and the design of the necklace is very bold. It is stamped Sterling Silver on the back of the center part of the necklace and it fastens with an old style spring ring catch. The sections of chain in the necklace look like they could be replacements but it is hard to be sure.
It measures 19 inches and the center portion is 1 1/4 inches square. It is in very nice condition except for a moderate amount of wear to the gold wash.
