• According to current knowledge Charoite is a silicate mineral that has exclusively been formed in an alkaline intrusion in Yakutia, Siberia (Russia). First descriptions of four polytypes date back to 1978. The picture shows the crystal unit cell of charoite-96 projected along the c*-axis which is based on data from Rozhdestvenskaya et al. (Mineralogical Magazine 75 (2011) 2833): blue = Si, red = O, yellow = Na, purple = K, green = Sr, Ba, Mn, light blue = Ca. The mineral name may be derived from Russian чароде́йство for magic and/or charme whereas some ascribe it to the Siberian river Chara.
