Physical properties
Hardness: 3.5-4 (Mohs); Color: Black to deep charcoal; Luster: Sub-metallic to vitreous; Crystal Structure: Amorphous; Fracture: Conchoidal; Specific Gravity: 1.8-2.0
Formation & geological history
Formed through the metamorphism of ancient organic-rich sediments (sapropel) dating back approximately 2 billion years (Paleoproterozoic Era). Primarily found in the Karelia region of Russia.
Uses & applications
Used in water purification, electromagnetic frequency (EMF) protection products, jewelry, and pigment production. High-quality 'Elite' Shungite is highly collectible.
Geological facts
Shungite is unique because it naturally contains fullerenes, a hollow carbon molecule shape. It is one of the oldest carbon-based rocks on Earth and is named after the village of Shunga in Russia.
Field identification & locations
Identify by its distinct black streak, lightweight feel, and its ability to conduct electricity (it will complete a circuit on a multimeter). Common in the Lake Onega area of Karelia.
