Physical properties
Hardness of 6.5-7 on the Mohs scale, earthy to vitreous luster, opaque brown color, and conchoidal fracture.
Formation & geological history
Formed from silica-rich fluids precipitating in sedimentary environments or volcanic fissures over millions of years.
Uses & applications
Used primarily for ornamental carvings, polished cabochons, and decorative jewelry.
Geological facts
Jasper has been utilized since ancient times for talismans, seals, and weaponry components due to its toughness.
Field identification & locations
Identified by its waxy luster and lack of cleavage; commonly found in riverbeds and mountainous regions worldwide.
