This is a beautiful vintage Bristol blue glass pendant set in 800 silver and enhanced with marcasites. There is a delicate flower in the center of the pendant and the setting has a beaded edge. It dates to at least the 1920s though it may be earlier. It is stamped 800 on the bail and it is suspended from a delicate chain which may not be original.
The pendant measures about 3/4 inch by 5/8 inch and the chain is 16 inches long. It is in very good condition.
