Physical properties
Hardness of 7 on Mohs scale. Colors range from yellow, brown, and red due to iron oxide impurities. Luster is waxy to dull, with a cryptocrystalline structure and conchoidal fracture.
Formation & geological history
Formed via the precipitation of silica-rich fluids in sedimentary environments or hydrothermal veins, often over millions of years.
Uses & applications
Used extensively for ornamental carvings, polished cabochons in jewelry, and decorative stone items.
Geological facts
Jasper has been used since ancient times for talismans, seals, and weaponry components by various civilizations globally.
Field identification & locations
Identify by its opaque nature, hardness scratching glass, and smooth waxy finish. Commonly found worldwide in riverbeds and mountainous regions.
