Tungsten is a very hard and dense metal with hardness between 8.5 and 9.5 on the Mohs hardness scale (Diamonds are a 10 - the highest). Its density, similar to that of gold, allows tungsten to be used in jewelry as an alternative to gold or platinum. Tungsten carbide is about 10 times harder than 18K Gold, four times harder than titanium, twice as hard as steel, and is the only rare and exotic metal that can be permanently polished. Your Tungsten Carbide ring will maintain it's virtually scratch resistant polished finish for decades when subject to normal wear. All rings come with a free ring Box.
