Physical properties
Hardness: 3.5-4 (Mohs scale); Color: Black or dark charcoal grey; Luster: Submetallic to matte; Crystal structure: Amorphous (non-crystalline); Cleavage: Conchoidal fracture; Specific gravity: 1.8-2.0
Formation & geological history
Formed through the metamorphism of ancient Precambrian organic sediments (algae and microorganisms) over 2 billion years ago. Primary deposits are found in the Karelia region of Russia.
Uses & applications
Used in water purification systems, as a pigment in paint, and extensively in the 'metaphysical' and wellness industry for jewelry and pocket stones. It is also used in metallurgy.
Geological facts
Shungite is unique for containing natural Fullerenes (C60/C70 molecules), which are powerful antioxidants. It is named after the village of Shun'ga in Karelia, Russia, where it was first described.
Field identification & locations
Identify in the field by its deep black color and its ability to conduct electricity (can be tested with an ohmmeter). It will leave a black streak if rubbed on a rough surface. Common in riverbeds and quarries in Karelia.
