Physical properties
Hardness of 6-7 on the Mohs scale, characteristic pistachio-green to yellowish-green color, vitreous luster, monoclinic crystal system, specific gravity around 3.3-3.5.
Formation & geological history
Formed through regional or contact metamorphism, often in hydrothermal veins and altered igneous or metamorphic rocks.
Uses & applications
Used primarily as mineral specimens for collectors and occasionally cut into cabochons for jewelry.
Geological facts
Epidote is a common indicator mineral for hydrothermal alteration zones, making it valuable in geological exploration for ore deposits.
Field identification & locations
Easily identified in the field by its distinct pistachio-green color, often associated with quartz and feldspar in metamorphic terrains.
