When you see this ring, you might do a tungsten double take. This ring is actually a rare, up-to-the-minute fusion of red and black carbon fiber with a black ceramic band. Black ceramic is almost as hard as tungsten; it's black onyx like color does not fade or scratch. Complete with beveled edges and comfort fit, this unique creation is available in 6 mm, 8 mm and 10 mm, for couples who want their rings to match. You can relax with your dazzling high-tech band, because you have our stress-free guarantee with every ring you buy receive: free lifetime warranty, free lifetime sizing with no sizing fee and no exchange fee, as you will find with many other dealers.
