Tungsten is a very hard and dense metal, mined from Wolframite ore and symbolized by a (W) on the periodic table of elements. It melts at an extraordinary 6,100 degrees Fahrenheit–the highest melting point of all metals. Tungsten does not gain its extreme hardness until it is combined with a carbon alloy, transferring it into Tungsten Carbide (WC) with a hardness between 8.5 and 9.5 on the Mohs hardness scale.
Tungsten Carbide is four times harder than titanium, twice as hard as steel, is virtually un-scratchable, and has been widely used for decades in industrial applications such as cutting tools, mining machinery, and rocket engine nozzles.
This makes a tungsten ring the prefect choice for someone who tends not to be delicate with their jewellery, and also is looking for a more contemporary look.
