A purple amethyst stone adds a flash of color to these pretty sterling silver flower earrings. The stone is held in a prong setting and framed by five brightly polished petals. These earrings are set on sterling silver posts with friction back closures and have a fairly substantial presence, with a diameter of about half an inch. Amethyst is the birthstone for the month of February. Its rich purple color contrasts beautifully with the bright gleam of polished silver.
