This is a beauty! It has a 1.5 ct cushion cut, bezel set, genuine amethyst set in solid .925 sterling silver. The sterling silver is oxidized so it is designed to have that blackened, tarnished look. The ring is 15 mm (9/16 inch) wide at the crown and tapers to 5 mm (3/16 inch) on the shank. It weighs 7.9 grams and is a size 8, sizable by your local jeweler.
