Vintage 1950s Marcasite and Sterling Pendant, Chain and Earrings Set. The pendant and earrings are each approximately 1/2" round; the chain is approximately 16" long. All are marked "STERLING"--the earrings on the back of the screw-backs; the back of the pendant; the jump ring of the chain. They seem to have their original rhodium plating; they are in the original gift boxes [somewhat scuffed] on navy blue velvet imprinted "Genuine Marcasite" also "Sterling Silver". The pendant has a little envelope on the back of the velvet insert to hold the chain. The bail for the pendant is unmarked.
