Physical properties
Hardness: 3.5-4 (Mohs); Color: Black or dark charcoal grey; Luster: Sub-metallic to matte; Structure: Amorphous; Cleavage: None; Specific Gravity: 1.8-2.0
Formation & geological history
Formed through the metamorphism of ancient Precambrian organic sediments (algae and bacteria), approximately 2 billion years ago, primarily in the Karelia region of Russia.
Uses & applications
Used in water purification, metallurgy, pigment production, and in the metaphysical/jewelry market as a protective stone.
Geological facts
Shungite is famous for containing 'fullerenes' (hollow carbon molecules like C60), which are rare in nature and believed to have antioxidant properties.
Field identification & locations
Identify by its light weight and ability to conduct electricity (test with an ohmmeter). It is found primarily in the Zazhoginsky deposit in Karelia.
