All our products are made of the third type of shungite from Karelia, Russia. This is black shungite. The carbon content is about 32%. It is this shungite that has become the object of worldwide scientific research in the field of EMF protection and water purification. There is also an elite shungite in our store. This is silver-colored shungite. However, this shungite is not suitable for the manufacture of products of geometric shapes because it is extremely fragile and difficult to process. Shungite, which contains more than 40% carbon, has a gray color and is also not suitable for making souvenirs (pyramids, spheres, pendants, etc.)
