Physical properties
Hardness of 6.5 to 7 on the Mohs scale, opaque red to reddish-brown color, and a vitreous to dull luster with conchoidal fracture.
Formation & geological history
Formed via the hydrothermal precipitation of silica-rich fluids or accumulation of silica in sedimentary environments, often during the Precambrian era.
Uses & applications
Widely used in ornamental carvings, cabochons for jewelry, and valued as a polishing and tumbling stone.
Geological facts
Red Jasper was historically used by ancient civilizations like the Egyptians to carve protective amulets and seals.
Field identification & locations
Easily identified by its deep red color, lack of cleavage, and ability to scratch glass; commonly found in riverbeds, hydrothermal veins, and sedimentary deposits worldwide.
