Physical properties
Hardness: 6-7 on Mohs scale. Color: Mottled green (epidote), black (hornblende), and white (quartz). Luster: Vitreous to dull. Crystal Structure: Hexagonal/Monoclinic system (polycrystalline). Specific Gravity: Approximately 2.6-2.7.
Formation & geological history
Formed through the regional metamorphism of igneous rocks, where hydrothermal fluids alter minerals like feldspar into epidote. These specific specimens are frequently found in South Africa and Australia.
Uses & applications
Primarily used for lapidary purposes, including semi-precious jewelry, carved decorative towers (as shown), spheres, and metaphysical or gemstone collecting.
Geological facts
Despite the trade name 'Jasper', this material is often more accurately a combination of Epidote and Pietersite or Hornblende. It is nicknamed for its lizard-skin or dragon-scale appearance.
Field identification & locations
Identify by its distinctive combination of pistachio-green epidote and dark inclusions. Collectors should look for high contrast between the green and black/white sections. Commonly found in metamorphic terrains.
