What are the origins of the word Tungsten?

Tungsten originates from the Swedish words 'tung sten' meaning heavy stone. It was formerly called Wolfram hence the symbol of the element - W.

Tungsten in its pure state is just a regular metal and does not posses the hardness and scratch resistance of tungsten-carbide (WC) and can scratch quite easily. Only when tungsten (W) is processed with carbon (C) and other elements, and compressed under extreme pressure and temperature, it is transformed into Tungsten Carbide (WC) - the hardest metal ever to be used in jewelry creations.

All our tungsten rings are cobalt free. There is no cobalt in any of our jewelry. This is very important as the presence of cobalt can cause an adverse reaction with human body, causing skin rashes and discoloration of the ring. What happens is: Skin oils can bond with cobalt, bringing it to the surface, resulting in discoloration similar to tarnishing. The cobalt spots cannot be removed by cleaning or even polishing.
