This lovely necklace comes from a local estate. If amethyst is your birthstone, you are going to LOVE it! Nice, deeply colored stone is set in a 14KT gold mount (marked) with six small diamond accents. Open-backed setting really lets the light come through. The pendant hangs from an 18 inch 14kt gold (marked) box chain with a lobster claw clasp. Pendant measures 3/4" long. Entire thing weighs .16 oz. A classic look at a fraction of the jewelry store price. This piece is about 30 years old.
