🌺Vintage Sterling Green Stone & Marcasite Necklace

Unique, vintage sterling silver necklace. This lovely piece has a rectangular pendant with a prong set half cylindrical green stone set in an ornate Marcasite frame. I do not know what the stone is, although it is the color of green Jadeite. The sterling chain is connected to two loops on the top corners of the pendant and there is shimmer from the Marcasites. It measures 18 inches long and the chain is stamped 925. C1 Will arrive boxed or in a jewelry pouch.
