Charoite. 2O is a rare silicate mineral, first described in 1978. It is named after the Chara River, despite its being 70 km away from the discovery place; the name of the river translated from Evenki means “to melt, melt.”. [6] [3] When it was discovered, it was thought to be a fake, dyed purple to give it its striking appearance.
Ametrine, also known as trystine or by its trade name as bolivianite, is a naturally occurring variety of quartz. It is a mixture of amethyst and citrine with zones of purple and yellow or orange. Almost all commercially available ametrine is mined in Bolivia. The colour of the zones visible within ametrine are due to differing oxidation states ...
Amethyst is a violet variety of quartz. The name comes from the Koine Greek αμέθυστος amethystos from α- a-, "not" and μεθύσκω ( Ancient Greek) methysko / μεθώ metho ( Modern Greek ), "intoxicate", a reference to the belief that the stone protected its owner from drunkenness.

Lapis is the Latin word for "stone" and lazulī is the genitive form of the Medieval Latin lazulum, which is taken from the Arabic لازورد lāzaward, itself from the Persian لاژورد lāžavard/lāževard and/or لاجورد lājevard. It means "sky" or "heaven"; so this is a "stone (of/from) the sky" or "stone (of/from) heaven". [11]
Kyanite is an aluminum silicate mineral, with the chemical formula Al2SiO5. It is typically patchy blue in color, though it can range from pale to deep blue [6] and can also be gray or white or, infrequently, light green. [7] It typically forms sprays of bladed crystals, but is less commonly found as distinct euhedral (well-shaped) crystals ...
Corundum is a crystalline form of aluminium oxide ( Al2O3) typically containing traces of iron, titanium, vanadium, and chromium. [3] [4] It is a rock -forming mineral. It is a naturally transparent material, but can have different colors depending on the presence of transition metal impurities in its crystalline structure. [7]
Purple liquid with atomic number 11 and symbol Re that makes a compound that produces clouds when exposed to air when mixed with Arsonium, and an antivirus when mixed with Nanite and Sanite. The real element 11 is sodium; and Re = rhenium. Residuum Critical Role, The Legend of Vox Machina: A mineral; can enhance arcane powers. Refined from ...
Calcite is a common constituent of sedimentary rocks, limestone in particular, much of which is formed from the shells of dead marine organisms. Approximately 10% of sedimentary rock is limestone. It is the primary mineral in metamorphic marble.
