Physical properties
Hardness: 6.5–7 on Mohs scale; Color: Deep red (hematite) and forest green (epidote); Luster: Vitreous to waxy; Crystal structure: Trigonal/Monoclinic; Specific Gravity: 2.6–2.9
Formation & geological history
Formed through the regional metamorphism of igneous rock, often in metamorphic belts. Its unique coloration comes from the combination of red jasper and green epidote minerals. This specific variety is primarily sourced from Western Australia.
Uses & applications
Primarily used for lapidary purposes including jewelry (beads, cabochons), ornate carvings, tumbled stones for collectors, and decorative home accents.
Geological facts
Despite its name, it is technically an epidote mineral combined with jasper. In folklore, it was once believed to be the remains of ancient dragons, where the green represented the skin/scales and the red represented the blood.
Field identification & locations
Identify by its distinctive mottled red and green appearance and high hardness (it cannot be scratched by a steel knife). Commonly found in the Turee Creek area of Australia. Collectors should look for vibrant, contrasting color patterns.
