Physical properties
Hardness: 6-7 on the Mohs scale. Color: Mottled green, pink, and white. Luster: Vitreous to dull. Crystal structure: Granular, phaneritic texture. Specific Gravity: 2.6-2.8.
Formation & geological history
Formed through the alteration of granite where plagioclase feldspar is replaced by epidote, green chlorite, and pink orthoclase. Geological age varies depending on the specific parent granite intrusion.
Uses & applications
Used as a decorative stone, carved into cabochons, beads, spheres, and tumbled stones for jewelry and lapidary arts.
Geological facts
Unakite was first discovered in the Unaka Mountains of western North Carolina, from which it derives its name. The striking green and pink contrast comes from the combination of green epidote and pink orthoclase feldspar.
Field identification & locations
Can be identified in the field by its distinct mottled pink and pistachio-green coloration. Commonly found in glacial drift derived from granitic terranes, such as the Blue Ridge Mountains in the US and various European localities.
