Physical properties

Hardness: 3.5-4.0; Color: Black, deep gray, or silver (Elite/Noble type); Luster: Submetallic to metallic; Structure: Non-crystalline; Cleavage: None (conchoidal fracture); Specific Gravity: 1.8-2.0

Formation & geological history

Formed through the metamorphism of ancient sedimentary organic matter (plankton and algae) during the Paleoproterozoic era, roughly 2 billion years ago, specifically in Karelia, Russia.

Uses & applications

Used for water purification, as a black pigment in paint, in metaphysical jewelry, and for alleged electromagnetic field (EMF) protection. Elite shungite is highly valued by collectors.

Geological facts

Shungite is unique for containing fullerenes (buckyballs), which are spherical carbon molecules. It is found almost exclusively in the Shunga region of Karelia, Russia.

Field identification & locations

Identify by its ability to conduct electricity (can be tested with an ohmmeter) and its soil-like black streak on a porcelain plate. Elite shungite has a shiny, glass-like appearance and does not stain hands, unlike common shungite.
