Black-Colored Stone & Silver Ring Size 10.5

This gorgeous statement cocktail ring features a multi-faceted black-colored glass stone outlined in a gold-tone metal on a detailed silver-tone ring. I think the ring is silver-plated and the gold detail is actual gold, but I'm not totally sure. Scratches on the smooth silver part from wear, otherwise GUC. Approximate ring size is 10.5. Jewelry box is included.
