Physical properties
Hardness of 6.5 to 7 on the Mohs scale, opaque luster, red to brown colors, and conchoidal fracture.
Formation & geological history
Formed through the precipitation of silica-rich fluids within sedimentary or volcanic environments over millions of years.
Uses & applications
Used primarily in lapidary arts, ornamental carvings, and affordable jewelry.
Geological facts
Jasper has been used since ancient times for talismans, seals, and tools due to its toughness and ability to take a high polish.
Field identification & locations
Identify by its opaque, earthy appearance and conchoidal breakage. Commonly found globally in hydrothermal veins and sedimentary deposits.
