This incredible 7mm comfort-fit Tungsten band features a high-polished finish with a center inlay of ceramic and double rounded edges. Tungsten is one tough metal indeed. It happens to be (10x) harder than gold or silver, (8x) harder than platinum and (2x) as hard as steel. The name comes from the words Tung and Stun which mean Heavy Stone in Swedish. Though Tungsten is extremely strong and scratch-proof, the only thing stronger than it is an actual diamond.
