Physical properties
Hardness of 6.5 to 7 on the Mohs scale, opaque luster, microcrystalline crystal structure, and a conchoidal fracture with various earthy colors.
Formation & geological history
Formed from silica-rich solutions precipitating in sedimentary environments or volcanic ash beds over millions of years.
Uses & applications
Used primarily for ornamental carvings, polished cabochons, jewelry, and as collector mineral specimens.
Geological facts
Jasper has been utilized by ancient civilizations since prehistoric times for tools, seals, and decorative amulets.
Field identification & locations
Identify by its opaque nature, microcrystalline quartz composition, and lack of cleavage. Commonly found worldwide in riverbeds and mountainous regions.
