Scheelite is a calcium tungstate mineral with the chemical formula CaWO4.
It is an important ore of tungsten. Scheelite fluoresces under shortwave ultraviolet light, the mineral glows a bright sky-blue.
Scheelite was first described in 1781 for an occurrence in Mount Bispbergs klack, Säter, Dalarna, Sweden, and named for Carl Wilhelm Scheele (1742–1786).
Owing to its unusual heaviness, it had been given the name tungsten by the Swedes, meaning “heavy stone.” The name was later used to describe the metal,
while the ore itself was given the name scheelerz or scheelite.
