Physical properties
Typically opaque, dark green to black with vivid red hematite/goethite patches; vitreous to waxy luster, Mohs hardness about 6.5–7, cryptocrystalline structure, no visible cleavage, and specific gravity near 2.6. This specimen is a polished cabochon or palm stone.
Formation & geological history
Forms when silica-rich fluids cement and replace volcanic or sedimentary material, with iron-bearing minerals producing the red zones; its exact geological age depends on locality. Common commercial material is associated with Western Australian jasper deposits.
Uses & applications
Used for cabochons, beads, carvings, palm stones, and decorative objects; it has modest collector value and no major industrial role.
Geological facts
“Dragon blood jasper” is primarily a trade name rather than a formally recognized mineral species; appearance varies widely and may overlap with epidote-rich or iron-stained jasper.
Field identification & locations
Identify it by its opaque, smoothly polished surface, very fine texture, lack of cleavage, and red-to-black patterning; jasper will not show quartz-like transparency. Common sources include Australia, South Africa, Madagascar, and India.
