A deep purple amethyst stone adds a colorful accent to this pretty circle pendant. The stone is bezel set in a small donut-shaped circle of smooth, polished sterling silver. A rectangular-link chain gives this necklace a fresh, modern look. The chain measures 16 inches and fastens with a lobster-claw clasp. Amethyst is the birthstone for the month of February. Its rich purple color contrasts beautifully with the bright gleam of polished silver.
