Shungite is a black stone made mostly of carbon, the same element that forms both graphite and diamonds. Its high carbon content is what gives it its distinctive light-sucking black colour, but unlike graphite, it is lustrous, and some high-quality examples have a silver reflect. It was discovered in the village of Shunga, in Russia, which is where it gets its name. One more unusual property of the stone shungite is its electric conductivity. This stone conducts electric current. One of the most widespread ways of checking that shungite is genuine is checking the electric conductivity of a sample with the help of a lamp and a battery bound into an electrical circuit. The main component of shungite is carbon C60.
