Shungite
Shungite (non-crystalline carbon mineraloid) · Collector Mineral / Decorative Stone
Crystal System
Amorphous (Non-crystalline); lacks a defined internal geometric structure
Mineral Group
Element (Native Non-metal); technically a mineraloid rather than a mineral
Chemical Formula
C (Carbon, typically 30-98%) with minor SiO2, Al2O3, and Fe2O3
Formation Process
Sedimentary/Metamorphic; formed from the metamorphosed remains of ancient microscopic organic matter and algae in oxygen-poor environments
About This Crystal
Opaque, black to charcoal grey material with a sub-metallic to matte luster. This specific specimen is carved into a feather shape. It often exhibits a smooth, stony texture and may show slight silver-grey streaks or spots of secondary minerals like pyrite or quartz.
Physical Characteristics
Color: Deep black to gunmetal grey; Streak: Black; Cleavage: None (amorphous); Fracture: Conchoidal to splintery; Specific Gravity: 1.8 - 2.0; Fluorescence: None; Conducts electricity (unique for most stony minerals)
Optical Properties
Opaque; No refractive index (n/a for opaque amorphous substances); No pleochroism or birefringence
Hardness & Durability
Origin Region
Karelia, Russia (Zazhoginsky mine near Lake Onega); found in ancient Precambrian rocks
Hardness & Durability
Mohs hardness: 3.5 - 4.0; Brittle tenacity; Low durability for heavy jewelry wear, easily scratched by steel or quartz
Care & Maintenance
Clean with warm soapy water and a soft cloth; avoid ultrasonic cleaners or harsh chemicals. It can leave a black residue on light fabrics and is soft enough to chip if dropped.
Rarity & Value
Relatively common in its industrial form, though high-carbon 'Elite' shungite is rarer. Carvings are inexpensive, typically ranging from $10-$40 depending on size and craftsmanship.
Special Characteristics
High electrical conductivity due to carbon content; contains fullerenes (unique carbon molecules); often used for shielding from electromagnetic frequencies (EMF) in folk practices.
Lore & History
Used in Russia since the time of Peter the Great for water purification. Symbolically associated with the Root Chakra and grounding. Traditionally believed to offer protection from negative energy and EMF radiation.
