Overview

Charoite ( CHAR-ow-ait) is a rare silicate mineral with the chemical composition K(Ca,Na)2Si4O10(OH,F)•H2O, first described in 1978. It is named after the Chara River, despite its being 70 kilometres (43 mi) away from the discovery place. When it was discovered, it was thought to be a fake, dyed purple to give it its striking appearance.
