Physical properties
Hardness of 6.5-7 on the Mohs scale, opaque brick-red color, waxy luster, and conchoidal fracture with no cleavage.
Formation & geological history
Formed through the precipitation of silica-rich fluids in marine or hydrothermal environments, often incorporating iron oxide impurities.
Uses & applications
Widely used for lapidary work, cabochons, beads, ornamental carvings, and holistic crystal collections.
Geological facts
Ancient cultures valued red jasper as a sacred protective stone and talisman for warriors. The red color is primarily due to hematite inclusions.
Field identification & locations
Identified by its dense red color and microcrystalline texture, commonly found worldwide in association with iron ore deposits.
