Physical properties

Formation & geological history

A decorative jasper formed when silica-rich fluids replaced or cemented volcanic rock, incorporating green epidote/chlorite and red iron- or manganese-bearing minerals; specimens are generally associated with ancient metamorphosed volcanic terrains. Commonly marketed from Western Australia, especially the Pilbara region.

Uses & applications

Used for cabochons, tumbled stones, carvings, ornaments, and lapidary collections; it has modest gemstone value rather than fine-jewelry rarity.

Geological facts

“Dragon blood jasper” is a commercial name, not a formally defined mineral species, and material sold under the name can vary considerably in composition.

Field identification & locations

Identify it by its polished green groundmass and irregular red blotches, opaque appearance, and lack of banding typical of many agates; confirm with hardness and specific-gravity tests. Common rough material comes from Australia and similar jasper deposits worldwide.
