Formation & geological history
Formed through the process of contact metamorphism where an alkaline massif intruded into limestone deposits. It is found in the Sakha Republic (Siberia), Russia, in the Murun Massif. It is dated to the Cretaceous period.
Uses & applications
Primarily used as an ornamental gemstone for cabochons, beads, carvings, and luxury interior inlay work.
Geological facts
Charoite is incredibly rare because it is found in only one location on Earth: the Chary River area in Siberia. Its name is derived from either the Chara River nearby or the Russian word 'chary', which means charms or magic.
Field identification & locations
Identify by its unique swirling 'fibrous' appearance and vibrant purple color which is unlike almost any other mineral. It is often associated with black aegirine or orange tinaksite inclusions.
