Anthracite vs Shungite
Anthracite and Shungite are easy to confuse. Shungite is harder (Mohs 3.5) than Anthracite (Mohs 2.5), so Shungite will scratch Anthracite and not the other way round. A copper coin (Mohs 3.5) scratches it, but a fingernail does not. Below is a side-by-side comparison of their properties and the quick tests that separate them.
Key differences between Anthracite and Shungite
- Shungite is harder (Mohs 3.5) than Anthracite (Mohs 2.5), so Shungite will scratch Anthracite and not the other way round. A copper coin (Mohs 3.5) scratches it, but a fingernail does not.
- Streak color differs: Anthracite leaves a black to dark gray streak on unglazed porcelain, Shungite leaves black.
- Both look metallic, so compare color, tarnish and weight rather than shine.

About Anthracite
Anthracite is a hard, shiny, high-carbon coal. It often looks black, compact, lightweight for its size, and glassy to submetallic.
About Shungite
Shungite is a black, carbon-rich rock found mainly in the Karelia region of northwestern Russia. It ranges from dull carbon-bearing rock to a lustrous high-carbon variety and is notable for its very old Precambrian age.
