Some information about shungite:
Shungite is a Precambrian carbonaceous rock of organic origin, which had been found only in Russia, Karelia, Lake Onega area. Its name comes from the small village of Shunga where it was first discovered. Scientists estimate the age of shungite to be almost 2 billion years. Though it is similar in appearance to coal, it is found in very ancient layers of the Earth’s crust that were formed when there were no life forms on the Earth.
There are two basic types of shungite. Typical shungite, which comes from Zazhoginskaya mine in Karelia, contains about 30% of carbon, 57% of silicates and 13% of other minerals like aluminium, iron, manganese oxides and some others. This material has black color, matt surface, sometimes with visible inclusions of other minerals.
The other type is so-called «noble» shungite (anthraxolite), which contains up to 94% of carbon. It has black color and metallic lustre. It comes in small quantities from Shunga village, but in general, it is a very rare type of shungite, and therefore, much more expensive (More information about shungite).
