Shungite is a stone high in carbon, (of which we humans are mostly composed of), which give it catalytic abilities, electroconductivity and chemical resistance. Found only in the Karelia of Russia, there are two varieties "classic" and "noble". The latter being higher in carbon and more rare. Shungite's ability to cleanse and align the atoms and molecules of the body to prepare it for infusion of spiritual light. Our physical bodies do not properly accept this "light" because we carry contradictions, disease and disharmony within. The highest purpose of Shungite is to facilitate this process and to rid one of negative emotional patterns.
