Why choose tungsten carbide for jewelry? 1.High hardness.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. 2.Green environmental protection. Tungsten carbide is a perfect choice for those who are allergic to some metal, because it is nickel free, lead free. 3.Daily maintenance is easy.you can wear tungsten carbide jewelry when swimming, taking shower, washing and working etc. It will not change color or break.
