Physical properties
Mohs hardness of 6.5 to 7, opaque red to brownish-red color, vitreous to dull luster, and microcrystalline crystal structure with no visible cleavage.
Formation & geological history
Formed via the precipitation of silica-rich fluids in marine or hydrothermal environments, often dating back to the Precambrian era.
Uses & applications
Commonly used in ornamental carvings, cabochons, jewelry, and metaphysical practices.
Geological facts
Red color is imparted by iron oxide impurities. It has been used for talismans and seals since ancient times.
Field identification & locations
Identify by its waxy luster, conchoidal fracture, and inability to be scratched by a steel knife. Found globally, especially in India, Brazil, and the USA.
