Physical properties
Hardness of 6.5 to 7 on the Mohs scale, typically opaque with a waxy luster, and features a microcrystalline quartz structure.
Formation & geological history
Formed from the precipitation of silica-rich fluids in sedimentary or volcanic environments, often during ancient hydrothermal activity.
Uses & applications
Commonly used in cabochons, carved ornamental objects, decorative jewelry, and as a popular specimen for rock collectors.
Geological facts
Jasper has been utilized since ancient times for talismans, seals, and weaponry due to its durability and rich coloration.
Field identification & locations
Identified by its conchoidal fracture, lack of cleavage, and resistance to steel scratching; widely found globally in riverbeds and mountainous regions.
