Physical properties
Hardness of 6.5 to 7 on the Mohs scale, opaque luster, various earth-tone colors, and trigonal crystal system.
Formation & geological history
Formed from silica-rich fluids precipitating in sedimentary environments or volcanic fissures over millions of years.
Uses & applications
Used primarily in ornamental carvings, cabochons, jewelry, and as a popular specimen for mineral collectors.
Geological facts
Jasper has been used since ancient times for amulets and seals, prized for its durability and rich color patterns.
Field identification & locations
Easily identified by its opaque nature and conchoidal fracture; commonly found worldwide in riverbeds and mountainous regions.
