This band ring is made exclusively with high quality Tungsten Carbide. Jewelry created from Tungsten are the most wear-resistant rings available, as Tungsten is 10x harder than 18K Gold, 5x harder than steel, and 4x harder than titanium. This ring will retain its shape and shine longer than any ring on the market, and contrary to popular belief, Tungsten rings are some of the safest rings to wear in an accident due to Tungsten Carbide being virtually unbendable. The element Tungsten Carbide measures a 9 on the Mohs Hardness Scale (highest classification being 10 or above). Tungsten rings have been referred to as the "Permanently Polished Rings".
