Physical properties

Hardness: 6.5-7.0 (Mohs scale), Color: brick red, cream, and brown, Luster: dull to vitreous, Crystal structure: microcrystalline (trigonal), Cleavage: none (conchoidal fracture)

Formation & geological history

Formed when original jasper is fractured through tectonic activity and then resealed with subsequent silica or hematite deposits filling the cracks.

Uses & applications

Used primarily in lapidary arts for cabochons, beads, decorative carvings, and as a popular grounding stone for metaphysical collectors.

Geological facts

The term 'brecciated' comes from the Italian word 'breccia', meaning broken gravel. It is essentially a 'healed' rock where the shards are held together by a natural mineral cement.

Field identification & locations

Identify by its characteristic fragmented patterns and high hardness (it will scratch glass but not be scratched by a steel knife). Commonly found in desert regions and volcanic deposits.
