Shungite
Shungite (non-crystalline carbon mineraloid) · Collector Mineral / Decorative Stone
Crystal System
Amorphous (Non-crystalline); usually found in massive or metamorphosed bitumen-like habits
Mineral Group
Native Elements (Carbon-rich mineraloid)
Chemical Formula
C (Carbon, typically 30-98%) with minor SiO2, Al2O3
Formation Process
Metamorphic; formed from the coalification of ancient organic Precambrian sediments (algae/plankton) under high heat and pressure
About This Crystal
An opaque, black, lusterous stone often appearing metallic or sub-metallic. In its tumbled form, it shows a smooth surface with occasional light grey or white veins (quartz or calcite) and minor surface pitting.
Physical Characteristics
Color: Deep black to charcoal grey; Streak: Black; Luster: Sub-metallic to vitreous; Specific Gravity: 1.84–1.98; Fracture: Conchoidal; Conductive to electricity.
Optical Properties
Opaque; No refractive index (amorphous); Non-pleochroic; Lacks dispersion or common optical phenomena like chatoyancy.
Hardness & Durability
Origin Region
Karelia, Russia (specifically the Shunga village, Lake Onega region)
Hardness & Durability
Mohs Hardness: 3.5 – 4.0; Brittle tenacity; Low wearability for jewelry due to relative softness and tendency to smudge skin.
Care & Maintenance
Avoid ultrasonic cleaners and harsh chemicals; clean with soft damp cloth; store separately from harder stones like quartz to prevent scratching.
Rarity & Value
Relatively common in massive form, but Elite/Noble Shungite (98% carbon) is rare; Value is generally low for tumbled stones, higher for large polished carvings.
Special Characteristics
Highly unusual for its high carbon content and the presence of naturally occurring fullerenes (C60, C70); extremely electrically conductive.
Lore & History
Historically used in water purification and thermal baths by Peter the Great; in modern metaphysical lore, it is believed to provide protection against EMFs and associated with the Root Chakra.
