Physical properties

Formation & geological history

Formed through the metamorphism and cementation of mineral-rich sedimentary layers where green epidote crystalizes alongside red jasper (quartz). Most high-quality specimens date back to the Precambrian or Paleozoic eras.

Uses & applications

Primarily used in jewelry (cabochons, rings, pendants), ornamental carvings, and holistic stone collections. In industry, it is mostly a decorative stone.

Geological facts

Despite its name, it is technically a combination of green epidote and red piedmontite/jasper. Local Australian legends suggest the stone represents the skin and blood of ancient dragons.

Field identification & locations

Identify in the field by its distinct 'reptilian' pattern of forest green and deep red veins. It takes a high polish and is primarily sourced from Western Australia and parts of South Africa. It can be identified by its hardness—it will not be easily scratched by a steel knife.
