Physical properties
Hardness: 3.5-4 (Mohs scale), Color: Black to deep charcoal grey, Luster: Sub-metallic to dull, Crystal structure: Amorphous, Specific gravity: 1.8-1.9
Formation & geological history
Formed through the metamorphism of ancient organic-rich sediments (sapropel) approximately 2 billion years ago during the Paleoproterozoic era.
Uses & applications
Used in water filtration, metallurgical industry, jewelry, pigments, and marketed for electromagnetic field (EMF) protection in alternative medicine.
Geological facts
Shungite is famous for containing fullerenes (buckyballs), which are carbon molecules with a cage-like structure. It is almost exclusively found in Russia.
Field identification & locations
Identify by its matte black streak, light weight compared to its appearance, and ability to conduct electricity (can be tested with a multimeter).
