Physical properties
Hardness of 6.5-7 on the Mohs scale, opaque brick-red color, dull to greasy luster, trigonal crystal system with conchoidal fracture.
Formation & geological history
Formed via the precipitation of silica-rich fluids in sedimentary environments or hydrothermal veins, often dating back to the Precambrian era.
Uses & applications
Used primarily in lapidary arts, ornamental carvings, cabochons, and as a popular collector mineral specimen.
Geological facts
Red jasper has been used since ancient times for talismans, seals, and weaponry components due to its toughness.
Field identification & locations
Identified by its dense red coloration, conchoidal fracture, and inability to be scratched by a steel knife. Commonly found worldwide.
