Physical properties

Formation & geological history

Formed from silicon-rich sediments in marine or hydrothermal environments that underwent tectonic stress, fracturing the rock, which was subsequently cemented back together by silica or other minerals.

Uses & applications

Used for jewelry, lapidary arts, decorative items, and as a collector specimen.

Geological facts

Brecciated jasper gets its distinctive mosaic pattern from natural fracturing of the original rock followed by healing with mineral-rich fluids.

Field identification & locations

Can be identified by its opaque red color, hardness, and broken, angular patterns cemented by veins. Commonly found worldwide including India, Brazil, Russia, and the USA.
