Physical properties
Hardness of 7 on the Mohs scale, vitreous to dull luster, conchoidal fracture, and multicolored with prominent red jasper and white quartz fragments.
Formation & geological history
Formed through hydrothermal fracturing and subsequent cementation of rock fragments by silica-rich fluids over millions of years.
Uses & applications
Used primarily in lapidary arts, cabochons, decorative carvings, and mineral collecting.
Geological facts
Brecciated jasper displays angular rock fragments cemented together, creating a natural mosaic pattern unique to each specimen.
Field identification & locations
Easily identified by its hardness, conchoidal fracture, and multicolored angular clasts; commonly found in fault zones and hydrothermal veins worldwide.
