Dragon Stone (Dragon Blood Jasper)
Quartz (var. Jasper) with Epidote and Pietersite/Chlorite inclusions · Semi-Precious Gemstone / Decorative Stone
Crystal System
Trigonal crystal system; microcrystalline/cryptocrystalline habit, typically found in massive forms
Mineral Group
Silicates (Tectosilicate group)
Chemical Formula
SiO2 (Silicon Dioxide) with Ca2(Al,Fe)3(SiO4)3(OH) (Epidote impurities)
Formation Process
Metamorphic or Hydrothermal; forms when silica-rich fluids permeate through volcanic or metamorphic rocks, incorporating local minerals like epidote and chlorite during crystallization
About This Crystal
An opaque, earthy stone featuring a mottled or veined blend of olive-to-khaki green (epidote) and deep red-to-maroon (jasper). The specimen in the image shows a polished 'tower' or obelisk shape with a waxy to vitreous luster and distinct green veining.
Physical Characteristics
Color: Green and red mottled; Streak: White; Luster: Vitreous to waxy; Cleavage: None; Fracture: Conchoidal to splintery; Specific Gravity: 2.6 – 2.9; Tenacity: Brittle but tough; Non-fluorescent.
Optical Properties
Refractive Index: 1.544 - 1.553; Opaque (no light transmission); Singly refractive; No pleochroism or dispersion visible due to opacity.
Hardness & Durability
Origin Region
Primarily sourced from Tshipise, Limpopo Province, South Africa; found in metamorphic and hydrothermal environments
Hardness & Durability
Mohs hardness: 6.5 to 7.0; High durability making it excellent for daily jewelry wear, ornaments, and pocket stones.
Care & Maintenance
Clean with warm soapy water and a soft brush; avoid harsh chemicals or ultrasound cleaners which might penetrate micro-fissures; store away from harder stones like diamonds to prevent scratching.
Rarity & Value
Relatively common; affordable pricing; value is determined by the balance of red and green patterns. It is rarely treated but sometimes stabilized with resin.
Special Characteristics
Known for its unique 'cryptocrystalline' texture where individual quartz crystals are too small to see with the naked eye, and its distinctive 'dragon-skin' pattern created by the interaction of different mineral inclusions.
Lore & History
Historically used in carvings and talismans; in modern crystal lore, it is believed to represent courage and strength ('blood of the dragon'). It is traditionally associated with the Heart and Root chakras to balance emotional and physical energy.
