Scheelite
Ca(WO4)
Scheelite is calcium tungstate, forming orange, honey or white pseudo-octahedral crystals on muscovite from Xuebaoding (Sichuan, China), and fluorescing bright blue-white under short-wave UV, which is how prospectors find it. Chinese scheelite on mica with cassiterite is a modern classic. Its heaviness and fluorescence separate it from fluorite and calcite.
