A poignant look. Polished purple amethyst drops (1-1/8 ct. t.w.) add a regal touch to a 14k gold leverback setting. Approximate drop: 1-1/8 inches. Almost all gemstones and blue and black diamonds have been treated to enhance their beauty and require special care. All gemstone carat weights (ct. t.w.), if mentioned, are approximate; variance may be .05 carat.
