Physical properties
Hardness of 6.5 to 7 on the Mohs scale, vitreous to dull luster, and conchoidal fracture. Displays angular fragments cemented together in contrasting color matrices like red, brown, and yellow.
Formation & geological history
Formed when broken rock fragments are naturally cemented together by silica-rich fluids within hydrothermal veins or fault zones.
Uses & applications
Commonly used for lapidary work, cabochons, beads, decorative carvings, and ornamental display pieces.
Geological facts
The brecciated pattern is created by tectonic forces shattering the original rock before mineral-rich groundwater heals the fractures.
Field identification & locations
Identified by its multicolored, fragmented mosaic appearance and a hardness that easily scratches glass. Found globally in regions with heavy tectonic or volcanic activity.
