Physical properties
Hardness of 6.5 to 7 on the Mohs scale, opaque red to reddish-brown color, waxy to dull luster, and a trigonal crystal system.
Formation & geological history
Formed via the precipitation of silica-rich fluids in sedimentary environments or hydrothermal veins, often dating back over a billion years.
Uses & applications
Used primarily in lapidary work, decorative cabochons, jewelry, and ornamental carvings.
Geological facts
Red jasper has been valued since ancient times as a protective talisman and sacred stone across various civilizations.
Field identification & locations
Identified by its rich red color, conchoidal fracture, and inability to be scratched by a steel knife; commonly found in riverbeds and silicate-rich deposits worldwide.
