The mineral charoite (also tscharoit or Čaroit) is a very rarely occurring inosilicate from the silicate mineral class. It crystallizes in the monoclinic crystal system with the general chemical composition (K,Na)5(Ca,Ba,Sr)8[(OH,F)|Si6O16|(Si6O15)2] · n H2O[5]. The elements potassium, sodium, calcium, barium and strontium listed in the round brackets, as well as the hydroxide ion and fluor within the square brackets, can substitute for one another in the formula, but always in the same proportion to the other components of the mineral.
Charoite forms translucent to opaque, massive or fibrous aggregates with violet and white banding, the bands being interwoven and sometimes containing dark inclusions. Charoite is highly sought after as a gemstone.
