Khorium

Khorium is a pink/purple fantasy metal obtained from Khorite

It is currently not used for anything but can be used as a sort of currency akin to diamond because of its rarity.

Khorium is from Blizzard's MMORPG; World of Warcraft. Khorium Veins are a rare spawn of Fel Iron or Adamantite Deposits, the ore is easily distinguished by its strikingly purple color and bizarre emanating waves of energy.
