Physical properties
Hardness of 6.5-7 on the Mohs scale, opaque luster, various colors including red, brown, and green, with conchoidal fracture.
Formation & geological history
Formed from silica-rich fluids precipitating in sedimentary environments or hydrothermal veins over millions of years.
Uses & applications
Used primarily in ornamental carvings, cabochons, jewelry, and as a collector specimen.
Geological facts
Jasper has been used since ancient times for talismans, seals, and weaponry components due to its toughness.
Field identification & locations
Identified by its dense, opaque appearance, lack of cleavage, and waxy luster; found worldwide in riverbeds and mountainous regions.
