Physical properties
Hardness: 6.5-7. Color: Deep red to brownish-red. Luster: Vitreous to dull. Crystal structure: Microcrystalline (trigonal). Cleavage: None. Specific gravity: 2.5-2.9.
Formation & geological history
Forms from the deposition of silica in sedimentary environments or as hydrothermal veins. The red color is due to iron inclusions.
Uses & applications
Used primarily as an ornamental stone, in jewelry making, and for carving. Also popular among collectors and in alternative healing practices.
Geological facts
Red Jasper has been used since antiquity for intaglios, seals, and amulets. It is considered a stone of grounding and stability in various metaphysical traditions.
Field identification & locations
Identified by its deep red color, opacity, and hardness. Often found as rounded pebbles in streams or polished stones. Common globally.
