Physical properties
Hardness: 3.5-4.0 (Mohs scale), Color: Black or deep charcoal gray, Luster: Submetallic to dull, Crystal structure: Amorphous, Specific gravity: 1.8-2.0
Formation & geological history
Formed through the metamorphism of ancient Precambrian sedimentary rocks containing organic material, dated to approximately 2 billion years ago.
Uses & applications
Used in water filtration systems, metallurgical industries as a carbon source, jewelry making, and widely sold in the metaphysical market for 'EMF protection'.
Geological facts
Shungite is famous for containing fullerenes (buckyballs), which are spherical carbon molecules. It is one of the oldest carbon-based minerals on Earth.
Field identification & locations
Identify by its ability to conduct electricity (test with a multimeter) and its tendency to leave a black mark on skin or surfaces. Predominantly found in the Karelia region of Russia.
