Physical properties

Hardness: 3.5-4 (Mohs); Color: Black or dark grey; Luster: Submetallic to metallic; Crystal structure: Amorphous; Cleavage: None; Specific Gravity: 1.8-2.0

Formation & geological history

Formed through the metamorphism of ancient organic sediments (algal or microbial) in the Paleoproteozoic era (approx. 2 billion years ago). Found primarily in the Karelia region of Russia.

Uses & applications

Used in water filtration, metallurgical processes, jewelry (beads and pendants), and as a pigment in paints (Shungite black).

Geological facts

It contains fullerenes, which are a unique form of carbon molecules. It is one of the oldest carbon-based substances on Earth and is named after the village of Shunga in Russia.

Field identification & locations

Identify by its distinct metallic sheen and tendency to leave a black smudge on skin or paper. It is commonly found in the Lake Onega area of Russia. Collectors should check for high carbon content which differentiates 'Elite' shungite from lower grades.
