This pretty old set is circa 1940s/50s. It is fashioned from gold colored metal, faux opals (glass) and prong set rhinestones. The earrings are screw back style and measure 3/4 X 1/2 inch and all of the stones are closed backed. The necklace chain measures 16 inches long and the heart shaped pendant (not including the bail) is 1/2 X 1/2 inches. The stones in the pendant are all closed backed. This delicate looking set is in very good condition.
