CHAROITE

Charoite ((Ca,K,Na) 3Si 4O 10 (OH,F)·H 2O) is a rare mineral, named for the Chara River (though this etymology is disputed by some), and found only in the Sakha Republic , Siberia , Russia . It is found w a syenite massif has intruded into and altered limestone deposits.

Charoite is a strong, translucent lavender to purple in color, reminding some of a granite or marble with its pearly, swirling luster. However, it is a discrete mineral rather than a rock, with a hardness of 5-6 and a specific gravity between 2.5 and 2.8. T is no cleavage, as 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 color, sometimes of a "grape" nature, can lead many to believe at first that it is synthetic or enhanced artificially.

Though reportedly discovered in the 1940s, it was not known to the outside world until its description in 1978. It is said to be opaque and unattractive when found in the field, a fact that may have contributed to its late recognition. Charoite is used as an ornamental stone and sometimes a gemstone, generally as cabochons set into pendants.

Russia has fairly strict prohibitions on the exportation of charoite. Generally, charoite is permitted to be exported only after the stone has been worked, for example, into figurines or other type ornaments. It is tfore difficult to procure "unworked" or "rough" charoite in a form suitable for further working into jewelry such as cabochons.

Charoite often contains inclusions of the mineral tennesite, which appears as golden a golden, spire-like shape running through the material.
