Tumbled; 1 pc. Approx. .75-1″ Note: This is Elite Noble Shungite- the most powerful Shungite available with the highest concentration of fullerenes. Shungite can only be found in Russia and there are two types: the more common darker low grade type and the shinier silver type. The higher quality shungite is also called silver shungite, noble shungite or elite shungite. These are considered the better quality shungite because they have a 70-94% carbon content rating containing more fullerenes. Noble shungite comes from the Zazhoginskoye deposit, near Lake Onega, in the Shunga region of Karelia, North West of Russia. Fullerenes are carbon based molecules that form into a spherical shape and are only found naturally in shungite.
