Physical properties
Hardness of 6.5-7 on the Mohs scale, opaque luster, various earth-tone colors including green and yellow, and conchoidal fracture.
Formation & geological history
Formed through the precipitation of silica-rich fluids in sedimentary or volcanic environments over millions of years.
Uses & applications
Used extensively in ornamental carvings, cabochons, jewelry, and polished display specimens.
Geological facts
Jasper has been used since ancient times for talismans, seals, and weaponry components due to its toughness and fracture properties.
Field identification & locations
Found worldwide in riverbeds and mountainous regions; identified by its opacity, waxy luster, and lack of crystal faces.
