Make a statement with this unique sterling silver thumb ring. It's crafted from solid .925 sterling silver (that's 92.5% pure silver mixed with alloys for strength), so it's quality jewelry that will last. The centerpiece is a beautiful blue simulated opal – it has that gorgeous, luminous play-of-color you love about opals, but in a more durable and affordable man-made stone. The design is a sleek band style, making it versatile enough to wear as a bold thumb ring or even as a simple pinky or middle finger ring. This one is a size 8. It's a great piece for someone who wants something a little different from a plain metal band – it's got a touch of color and personality. Whether it's for yourself or as a gift, it's a solid piece of jewelry that comes with a satisfaction guarantee. New and ready to wear.
