This bold 10mm black tungsten ring not only looks tough, but actually is tough. It is made of heavy tungsten carbide and light weight ceramic to give the ring the perfect weight. Both tungsten and ceramic are extremely scratch resistant. Unlike black tungsten, black ceramic is not a coating, and even if you manage to scratch the black ceramic, it will not show because it is black all the way through. This ring has a polish glossy finish. Free Lifetime Warranty! Click on image below picture of ring for details.
