Physical properties
Hardness of 6.5 to 7 on the Mohs scale, earthy or vitreous luster, opaque brown and tan coloration with microcrystalline quartz inclusions, conchoidal fracture.
Formation & geological history
Formed through the deposition and precipitation of silica-rich fluids in sedimentary or hydrothermal environments over millions of years.
Uses & applications
Commonly used for lapidary work, cabochons, ornamental carvings, and geological specimen collecting.
Geological facts
Jasper is an ancient gemstone utilized since antiquity for talismans, seals, and weaponry components like arrowheads due to its toughness.
Field identification & locations
Identified by its waxy luster, lack of cleavage, and inability to be scratched by a steel knife; found globally in riverbeds and mountainous regions.
