Shungite
Shungite (Non-crystalline carbonaceous mineraloid) · Mineral Specimen / Decorative Stone
Crystal System
Amorphous (Non-crystalline). Habit is typically massive, matte, or sub-metallic rocks; Elite/Noble variety is glassy with conchoidal fracture.
Mineral Group
Native Elements (Carbon-rich mineraloid)
Chemical Formula
C (Carbon, typically 30-98%) with traces of Fullerenes (C60, C70) and Silicates
Formation Process
Sedimentary/Metamorphic. Formed from the metamorphosis of ancient organic sediments (precambrian algae/plankton) under high pressure and temperature.
About This Crystal
An opaque, black, non-crystalline mineraloid. Low-grade shungite is matte or dull grey-black, while 'Elite' or 'Noble' shungite has a bright sub-metallic to vitreous luster with a sleek, coal-like appearance and deep black color.
Physical Characteristics
Color: Black to dark grey; Streak: Black; Cleavage: None; Fracture: Conchoidal to uneven; Specific Gravity: 1.8 - 2.0; Fluorescence: None. Highly conductive to electricity.
Optical Properties
Opaque (does not transmit light). Luster ranges from earthy/dull to sub-metallic or vitreous in high-carbon specimens. No birefringence or pleochroism due to amorphous structure.
Hardness & Durability
Origin Region
Karelia region of Russia (Shunga village); typically found in Precambrian sedimentary-volcanic sequences.
Hardness & Durability
Mohs Hardness: 3.5 - 4.0. Relatively soft and brittle; can be scratched by harder stones or metal. Low toughness; prone to chipping.
Care & Maintenance
Avoid harsh chemicals and ultrasonic cleaners. Clean with soft cloth and warm soapy water. Dry thoroughly. Carbon may rub off onto skin/clothing for lower grade specimens.
Rarity & Value
Common (Standard grade) to Uncommon (Elite/Noble grade). Value is determined by carbon content; 'Elite' shungite with >90% carbon is much more expensive.
Special Characteristics
Natural electrical conductivity (uncommon for non-metallic rocks). Contains natural fullerenes (spherical carbon molecules).
Lore & History
Historically used in Russia since the time of Peter the Great for water purification. Metaphysically associated with grounding, protection from EMF (electromagnetic frequencies), and purification of the Root Chakra.
