This vintage pendant necklace is made of 925 sterling silver with a beautiful round pendant shape hanging from a box chain. The necklace is 24 inches long and features a stunning blue stone as the main stone. The snake chain adds to the overall elegance and style of this piece, making it perfect for any occasion. The necklace's country of origin and the main stone creation are unknown, but this only adds to its mystery and charm. The necklace would make a great addition to any jewelry collection, and its unique design is sure to catch the eye of anyone who sees it. I am uncertain of the stone name.
