This is a gorgeous vintage Art Deco era necklace with faceted blue Czech glass stones set in a filigree setting. The design features a bezel set oval stone in a rectangular filigree setting. It is suspended from two small square stones and a larger square stone is pendant from the center section. The metal appears to be silver over brass.
It is 17 inches long and it is in very nice condition. I believe the spring ring catch is a replacement. There is some wear to the silver finish on the back of the filigree and some very tiny fleabites and light surface scratches typical of jewelry of this type and age but nothing that detracts.
