Physical properties
Hardness: 6.5-7 on Mohs scale; Color: Mottled forest green with deep red veins/patches; Luster: Vitreous to waxy; Crystal structure: Trigonal (microcrystalline); Cleavage: None; Specific Gravity: 2.6-2.9.
Formation & geological history
Formed through the regional metamorphism of igneous rocks, where basaltic materials are altered into epidote (green) and piemontite or iron oxides (red). It is typically found in Precambrian or Paleozoic geological formations.
Uses & applications
Primarily used for lapidary work, jewelry (cabochons, beads), decorative carvings, and as a popular specimen for crystal healing and mineral collecting.
Geological facts
Despite the name, it is technically an epidote-quartzite and not a true 'jasper' (which is a variety of chalcedony). It is historically associated with legends of dragons, where the green represents the dragon's skin and the red represents its blood.
Field identification & locations
Identify in the field by its distinct green and red mottling and its high hardness (it will scratch glass). It is most famously and almost exclusively sourced from Western Australia (Tieman Range).
