Regal Coro amethyst rhinestone demi-parure consisting of a necklace and screwback earrings. The curvaceous goltone settings contain prongset emerald shaped rhinestones and round rhinestones in a deep purple color. The necklace has a goldtone chain that measures 15 1/2" long. The pendant portion 1" x 15/16". The bezels on both the necklace and the earrings are riveted and secure. The earrings measure 3/4" x 7/8". All pieces are marked Coro in script. This vintage costume jewelry set is in excellent condition. Circa 1950s, I would think.
