Shungite

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).
