Physical properties
Hardness is 6 to 7 on the Mohs scale. Colors are a mottled mix of pink, green, and clear to grey, with a vitreous to dull luster.
Formation & geological history
Formed through the hydrothermal alteration or metamorphism of granite, typically occurring when heated fluids alter the original feldspar into green epidote.
Uses & applications
Commonly cut and polished into cabochons for jewelry, tumbled stones, spheres, and decorative architectural tiles.
Geological facts
First discovered in the Unakas Mountains of North Carolina, from which it derives its distinctive name. It is a popular lapidary stone for beginners due to its striking color contrast.
Field identification & locations
Easily identified by its unique speckled combination of pink feldspar and pistachio-green epidote. Commonly found in glacial drift derived from the Blue Ridge Mountains.
