Physical properties
Hardness of 6.5 to 7 on the Mohs scale, earthy to vitreous luster, opaque green color due to iron impurities, and conchoidal fracture with no distinct cleavage.
Formation & geological history
Formed through the deposition of silica-rich fluids in sedimentary environments or hydrothermal veins, often over millions of years.
Uses & applications
Used in ornamental carvings, cabochons, jewelry, and by rock collectors.
Geological facts
Jasper has been used since ancient times for talismans, seals, and weaponry. Green varieties are associated with grounding and harmony.
Field identification & locations
Identified by its waxy-to-earthy luster, inability to be scratched by a steel knife, and opaque green coloration. Commonly found in riverbeds and mountainous regions worldwide.
