Physical properties
Hardness: 6.5-7 (Mohs scale). Color: Primarily shades of deep green with streaks or patches of red. Luster: Vitreous to waxy. Crystal Structure: Trigonal/Monoclinic mix (granular). Cleavage: None.
Formation & geological history
Formed through regional metamorphism in Western Australia. It is a unique combination of green Epidote and red Piedmontite or iron inclusions, often found in ancient metamorphic rock beds over 2 billion years old.
Uses & applications
Used primarily for ornamental purposes, jewelry (beads, cabochons), carvings, and as a popular specimen for crystal healing and mineral collectors.
Geological facts
Despite being called 'Jasper', it is geologically more of an Epidote-rich rock. Legend says the green represents the dragon's skin and the red represents its blood, giving it its trade name.
Field identification & locations
Identify in the field by its distinct forest green base and contrasting red swirls. It is tough and resistant to weathering. Common locations: Tascotal Mesa, Western Australia.
