Amethyst's rich violet is one of nature's most striking colors. Our amethyst jewelry - earrings, rings and pendants - is set in 585 (14K) gold and 925 sterling silver, often framed with diamonds or cubic zirconia that make the purple glow even deeper. February's birthstone has long been associated with clarity and calm. Whether as a birthday gift or a bold accent for evening wear, amethyst always draws the eye.
