Physical properties
Hardness of 6-7 on the Mohs scale, featuring distinct mottled green and pink/orange colors with vitreous luster, cryptocrystalline to microcrystalline structure, and uneven fracture.
Formation & geological history
Formed through hydrothermal alteration of granitic rocks, where hot fluids alter plagioclase feldspar into epidote, commonly found in mountain-building regions.
Uses & applications
Used primarily in lapidary arts for cabochons, beads, carved decorative objects, and as a popular tumbled stone for collectors.
Geological facts
Unakite was first discovered in the Unaka Mountains of North Carolina, from which it derives its name.
Field identification & locations
Easily identified by its unique, vivid combination of pink orthoclase feldspar and green epidote; found globally including in the USA, South Africa, and Brazil.
