Shiva Lingam
Cryptocrystalline Quartz (Jasper) with Iron Oxide / Sediment Mixture · Decorative Stone / Sacred Mineral Specimen
Crystal System
Trigonal (Cylindrical habit due to river tumbling and hand polishing)
Mineral Group
Silicates (Tectosilicates)
Chemical Formula
SiO2 (Silicon Dioxide) with impurities of Fe2O3 (Hematite) and various carbonates
Formation Process
Sedimentary/Metamorphic: Naturally tumbled by river currents and composed of jasper found in the river beds of central India.
About This Crystal
Composed of cryptocrystalline quartz (Jasper) featuring a smooth, waxy to vitreous luster. This specimen is opaque with a base color of dull brown to gray-black, accented by concentric or banded patterns of tan, reddish-brown, or cream. The shape is typically elongated and rounded, though this specific piece has been carved into a crescent or ‘C’ shape.
Physical Characteristics
Color: Dark brownish-black with tan banding; Streak: White or brownish; Cleavage: None; Fracture: Conchoidal to uneven; Specific Gravity: 2.6 - 2.8; Fluorescence: Generally none.
Optical Properties
Refractive Index: Approx. 1.54; Birefringence: None (cryptocrystalline aggregate); Opacity: Opaque; Luster: Dull to waxy.
Hardness & Durability
Origin Region
Narmada River in Onkar Mandhata, Madhya Pradesh, India
Hardness & Durability
Mohs Hardness: 6.5 to 7.0; Toughness: Very high (resistant to chipping); Stability: Stable against light and most chemicals; Wearability: Excellent.
Care & Maintenance
Clean with warm soapy water and a soft cloth. Avoid harsh chemicals or acids which may react with carbonate impurities; store away from harder gems like sapphire or diamond.
Rarity & Value
Common; Value is determined primarily by the clarity of the markings (yoni/lingam symbols) and size. Generally inexpensive decorative or ritual items.
Special Characteristics
Naturally shaped by river movement (though often hand-finished); features distinct 'earth-tone' banding caused by iron oxide concentrations during sedimentation.
Lore & History
Highly significant in Hinduism as a symbol of the god Shiva and the duality of creation (male/female energy). Historically gathered once a year during a specific ceremony in the Narmada River. Traditionally believed to resonate with the root and sacral chakras for grounding and vitality.
