Physical properties
Hardness of 6.5 to 7 on the Mohs scale, opaque green color due to iron impurities, waxy to vitreous luster, and conchoidal fracture.
Formation & geological history
Formed via the precipitation of silica-rich fluids in sedimentary or volcanic environments over millions of years.
Uses & applications
Commonly used for ornamental carvings, polished cabochons in jewelry, and decorative landscaping stones.
Geological facts
Jasper has been used since ancient times for talismans, seals, and weaponry components across various civilizations.
Field identification & locations
Identified by its dense green color, lack of cleavage, and ability to scratch glass; found globally in riverbeds and mountainous regions.
