Physical properties
Hardness of 6.5 to 7 on the Mohs scale, color ranges from yellow, brown, red to green, vitreous to dull luster, cryptocrystalline structure, conchoidal fracture, specific gravity around 2.65.
Formation & geological history
Formed through the precipitation of silica-rich fluids in sedimentary or volcanic environments, often during hydrothermal activity or diagenesis.
Uses & applications
Used primarily in ornamental carvings, cabochons, jewelry, and as a collector's mineral specimen.
Geological facts
Jasper has been used since ancient times for seals, signet rings, and talismans by various civilizations including the Egyptians, Greeks, and Romans.
Field identification & locations
Can be identified by its opaque nature, waxy luster, and conchoidal fracture. Commonly found worldwide in riverbeds, sedimentary deposits, and volcanic regions.
