Shungite
Carbon mineraloid var. Shungite · Mineral Specimen / Decorative Stone
Crystal System
Amorphous (Non-crystalline)
Mineral Group
Native Elements (Carbon)
Chemical Formula
C (Amorphous carbon with fullerenes, C60 and C70, and silicate minerals)
Formation Process
Biogenic and sedimentary deposition in ancient shallow seas, followed by low-grade regional metamorphism over two billion years.
About This Crystal
An opaque, jet-black to dark grey amorphous mineraloid exhibiting a sub-metallic to vitreous luster on fresh surfaces and a matte appearance elsewhere. The specimen displays uneven to conchoidal fracture patterns with a smooth, slightly undulating surface texture.
Physical Characteristics
Color is deep black to dark grey. Streak is black. Cleavage is none due to its amorphous structure. Fracture is distinctly conchoidal. Specific gravity is approximately 1.84 to 1.98. Tenacity is brittle. It can exhibit electrical conductivity due to its unique carbon cage structure (fullerenes).
Optical Properties
Opaque with a sub-metallic luster on polished surfaces. Not transparent or translucent, therefore refractive index and birefringence are not applicable.
Hardness & Durability
Origin Region
Karelia, Russia (specifically the Onega Lake region)
Hardness & Durability
Mohs hardness is around 3.5 to 4. Moderately soft and brittle. Care must be taken to avoid scratching against harder minerals.
Care & Maintenance
Clean with mild soap and warm water. Avoid harsh chemical cleaners and ultrasonic cleaners. Store separately in a soft pouch to prevent scratching.
Rarity & Value
Uncommon globally due to its extremely limited geographic origin in Karelia, Russia. Value depends on carbon content and purity, ranging from affordable raw specimens to higher-priced elite shungite pieces.
Special Characteristics
Contains natural fullerene molecules (spherical carbon molecules), exhibits electrical conductivity, and is traditionally associated with water purification properties.
Lore & History
Historically used by Peter the Great who established Russia's first spa in Karelia after experiencing the healing waters filtered through shungite rocks. In modern metaphysical practices, it is considered a powerful grounding stone associated with the root chakra, believed by practitioners to absorb negative energy and electromagnetic frequencies (EMF).
