Shungite
Shungite (Amorphous non-crystalline carbon / Carbon-rich rock) · Mineral Specimen / Decorative Stone
Crystal System
Amorphous; typically occurs in massive or carborized forms without a distinct crystal habit.
Mineral Group
Native Elements (Carbon-rich mineraloid)
Chemical Formula
C (Carbon) + SiO2 (Silica) + Al2O3 (Alumina) + trace elements/fullerenes
Formation Process
Metamorphic / Sedimentary; formed through the metamorphism of ancient Precambrian organic-rich sediments.
About This Crystal
Black, coal-like appearance with a sub-metallic to dull luster. This specimen shows a rugged, rocky texture with silver-grey metallic sheen in some areas and a matte, dark grey/black body color. Opaque.
Physical Characteristics
Color: Black to dark grey; Streak: Black; Cleavage: None; Fracture: Conchoidal to uneven; Specific Gravity: 1.8 - 2.0; Non-fluorescent.
Optical Properties
Opaque; No refractive index (amorphous); Sub-metallic to dull luster; No birefringence or pleochroism.
Hardness & Durability
Origin Region
Karelia, Russia (near the Shunga village) in Paleoproterozoic geological formations.
Hardness & Durability
Mohs hardness: 3.5 - 4.0; Brittle tenacity; Low durability for jewelry, susceptible to scratches and abrasion.
Care & Maintenance
Clean with warm soapy water and a soft cloth; avoid ultrasonic cleaners and harsh chemicals. Store separately to avoid scratching from harder stones.
Rarity & Value
Relatively common in lower grades; 'Elite' or 'Noble' shungite (high carbon content) is rarer and more valuable. Fairly inexpensive for standard specimens.
Special Characteristics
Highly conductive to electricity; notable for containing natural 'Fullerenes' (C60/C70 carbon molecules).
Lore & History
Historically used in Russia as a water purification agent since the time of Peter the Great. In metaphysical lore, it is associated with protection from EMF radiation and 'root chakra' grounding.
