Our Deco Open Back Crystal necklace will make a wonderful Fall accessory. The open back faceted amber crystals can be layered or worn on their own and are just perfect for a Fall Home coming dance or prom. This vintage necklace dates back to at least 1930. It will adorn your neck at 15'' with 8mm crystals. They are joined at the tops to allow the silver toned metal chain to gracefully follow the curve of the neck. The metal is un marked and has not been tested for silver content. Age appropriate wear.
