Shungite

Physical Properties

Hardness: 3.5-4 (Mohs); Color: Matte black to metallic silver; Luster: Sub-metallic to vitreous; Crystal Structure: Amorphous; Cleavage: None; Specific Gravity: 1.8-2.0

Formation & Geological History

Formed through the metamorphism of ancient Precambrian organic sediments (algae and prokaryotes) roughly 2 billion years ago, likely in a marine or lagoonal environment.

Uses & Applications

Used in water filtration, as a black pigment in paint, for electromagnetic field (EMF) shielding claims, and extensively in the gemstone/metaphysical market.

Geological Facts

Shungite is unique because it naturally contains fullerenes (C60), a specific molecular form of carbon. Over 98% of the world's supply comes from the Karelia region of Russia.

Field Identification & Locations

Identify in the field by its dark black color and ability to conduct electricity. A simple multimeter test for conductivity can distinguish genuine Shungite from imitation black stones like onyx or obsidian.
