Physical properties
Hardness of 6.5 to 7 on the Mohs scale, waxy luster, opaque, and comes in various multicolored patterns with conchoidal fracture.
Formation & geological history
Forms from the precipitation of silica-rich fluids in sedimentary basins or volcanic environments over millions of years.
Uses & applications
Used extensively for ornamental carvings, jewelry, and polished collector specimens.
Geological facts
Jasper has been used since ancient times for talismans, seals, and weaponry like arrowheads due to its durability.
Field identification & locations
Identify by its opacity, hardness, smooth waxy texture, and lack of cleavage. Found worldwide in riverbeds and mountainous regions.
