Physical properties
Hardness of 6.5-7 on the Mohs scale, opaque luster, earthy to waxy appearance, 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
Widely used for ornamental carvings, polished cabochons, decorative items, and lapidary collecting.
Geological facts
Jasper has been utilized since ancient times for talismans, seals, and weaponry due to its durability and striking patterns.
Field identification & locations
Identify by its opaque nature, lack of cleavage, and smooth waterworn texture in riverbeds worldwide.
