Physical properties
Hardness 6.5 to 7 on the Mohs scale, various shades of green, waxy to vitreous luster, cryptocrystalline structure, conchoidal fracture.
Formation & geological history
Formed by the precipitation of silica-rich fluids in sedimentary basins or volcanic environments over millions of years.
Uses & applications
Used in ornamental carvings, jewelry making, and as a popular specimen for mineral collectors.
Geological facts
Jasper has been used since ancient times for talismans, seals, and weaponry due to its durability and rich color.
Field identification & locations
Identified by its microcrystalline texture, lack of cleavage, and ability to take a high polish. Found worldwide in riverbeds and mountainous regions.
