Physical properties

Hardness: 3.5-4 (Mohs); Color: Matte black to metallic gray/black; Luster: Submetallic or matte; Crystal Structure: Amorphous; Cleavage: None; Specific Gravity: 1.8-2.0

Formation & geological history

Formed from the metamorphosis of Precambrian organic-rich sediments, typically found in deposits dated over 2 billion years old (Paleoproterozoic era). It is primarily associated with volcanic-sedimentary sequences.

Uses & applications

Used in water filtration, metallurgical fuels, pigments for black paints, and increasingly in metaphysical circles or jewelry as 'protection' stones or decorative carvings.

Geological facts

Shungite is famous for containing fullerenes (buckyballs), which are spherical carbon molecules. It is found almost exclusively in the Karelia region of Russia. Its exact biological origin remains a subject of scientific debate due to its extreme age.

Field identification & locations

Identify by its ability to conduct electricity (can be tested with a multimeter), its black streak on a porcelain plate, and the soot-like residue left by lower-grade specimens. Found mainly in the Shunga village area of Karelia, Russia.
