Physical properties
Hardness of 6-7 on the Mohs scale, predominantly green and yellow-green coloration with a white/quartz vein, vitreous to dull luster, granular to massive crystal structure, specific gravity around 3.3-3.5.
Formation & geological history
Formed through regional or contact metamorphism of igneous or sedimentary rocks rich in calcium, iron, and aluminum, often associated with hydrothermal alteration.
Uses & applications
Used primarily as a mineral specimen for collectors, sometimes cut and polished into cabochons for jewelry.
Geological facts
Epidote derives its name from the Greek word for 'increase,' referring to the base of its crystal being longer than usual. The distinct contrasting vein is usually hydrothermal quartz that filled a fracture in the host rock.
Field identification & locations
Easily identified by its characteristic pistachio-green or yellowish-green color and the presence of contrasting quartz veins. Commonly found in metamorphic terrains worldwide.
