Charoite is a rare silicate mineral, first described in 1978 and named for the Chara River.
Charoite is translucent lavender to purple in colour with a pearly lustre. Charoite is strictly massive in nature, and fractures are conchoidal. It has an unusual swirling, fibrous appearance, sometimes chatoyant, and that, along with its intense colour, can lead many to believe at first that it is synthetic or enhanced artificially.
Occurrence: In potassic feldspar metasomatites at the contact of nepheline and aegirine syenites with limestones.
Charoite occurs in association with tinaksite and canasite.
Name: For the Chara River, Russia, near which it was discovered.
Colour:Violet to deep lilac
Hardness:5 - 6 on Mohs scale
Cleavage:Distinct/Good. Good in three directions
