One of the loveliest aspects of the best Charoite gems is a slight to moderate chatoyancy which gives it a silky or pearly luster. This attribute, as well as the swirling patterns and distinctive purple color, is well demonstrated by the piece above.
This is a natural untreated stone which is found in only one location in the world-at the Charo river Aldan Russia.
Color: The colors in each piece of Charoite range from bright lavender, violet and lilac to dark purple with both white, gray and black veining. It forms a swirling pattern of interlocking crystals. Royal lavendar flows with chatoyant streaks of white around bits of black, peach and opalescent gray.
Description: Charoite is an unsual mineral and of rare occurence. It formed from alteration of limestones by the close presences of an alkali-rich nephline syenite intrusion. The heat, pressure and more importantly, the infusion of unique chemicals into the rock is responsible for the transformations into new minerals such as charoite.
