Physical properties
Hardness of 6.5-7 on the Mohs scale, opaque luster, multicolored patterns including reds, browns, and greens, with a microcrystalline crystal structure and conchoidal fracture.
Formation & geological history
Formed through the silification of sedimentary or volcanic deposits, often precipitating from silica-rich fluids in marine environments over millions of years.
Uses & applications
Widely used in ornamental carvings, cabochons for jewelry, and as a popular specimen for rock collectors.
Geological facts
Jasper has been utilized since ancient times for talismans, seals, and weaponry components across various global civilizations.
Field identification & locations
Identify by its opaque nature, high hardness, and complex multicolored matrix. Commonly found worldwide, especially in alluvial deposits and ancient riverbeds.
