Physical properties
Hardness of 6.5-7 on the Mohs scale, opaque luster, microcrystalline quartz structure, and specific gravity around 2.65.
Formation & geological history
Formed from silica-rich fluids precipitating in sedimentary environments or volcanic fissures over millions of years.
Uses & applications
Used primarily in lapidary arts, ornamental carvings, jewelry, and as a collector's mineral specimen.
Geological facts
Jasper has been used since ancient times for seals, talismans, and decorative weaponry due to its durability and rich coloration.
Field identification & locations
Identify by its waxy luster, conchoidal fracture, and inability to be scratched by a steel knife. Commonly found globally in riverbeds and mountainous regions.
