Physical properties
Hardness of 6.5-7 on the Mohs scale, opaque brown color, waxy to vitreous luster, and conchoidal fracture.
Formation & geological history
Formed through the precipitation of silica-rich fluids in sedimentary or volcanic environments over millions of years.
Uses & applications
Commonly used for ornamental carvings, cabochons, jewelry, and lapidary art.
Geological facts
Jasper has been used since ancient times for seals, talismans, and decorative items due to its durability and rich earth tones.
Field identification & locations
Identified by its opaque nature, lack of cleavage, and smooth waxy finish; found globally in riverbeds and ancient mineral deposits.
