Some interesting information about charoite:
Charoite is an unsual mineral and of rare occurence. It is found to date in only one location: along the Chary River at Aldan in Russia. 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. Why charoite has not been found in other locations is not fully understood. But it is probably due to a combination of a chemically unique limestone reacting with a chemically unique intrusion and subjected to unique physical conditions.
Charoite is used as an ornamental stone and as a gemstone. It forms a swirling pattern of interlocking crystals. The color of charoite is described as a stunning lavender, lilac, violet and/or purple. All can be used as all are probably present in every swirling example. The look of charoite is unlike any other mineral and can't be mistaken. It has the appearance of purple marble, but really defies description. Its popularity would probably be much greater if not for its "synthetic" character. It simply looks unnaturally beautiful.
