Physical properties
Hardness of 6.5 to 7 on the Mohs scale, opaque red color due to iron inclusions, waxy luster, and conchoidal fracture.
Formation & geological history
Formed by the precipitation of silica-rich fluids in sedimentary environments or hydrothermal veins, often dating back over a billion years.
Uses & applications
Used primarily in ornamental carvings, cabochons, lapidary arts, and as a collector mineral.
Geological facts
Red jasper has been used since ancient times for talismans, seals, and weaponry components by various civilizations worldwide.
Field identification & locations
Easily identified by its deep red color, hardness that scratches glass, and lack of cleavage; commonly found in stream beds and metamorphic-sedimentary contact zones.
