Physical properties
Hardness of 6-7 on the Mohs scale, distinct mottled green and pink coloration, vitreous to dull luster, and massive or granular crystal structure.
Formation & geological history
Formed through the hydrothermal alteration of granite, where hot fluids alter plagioclase feldspar into green epidote.
Uses & applications
Widely used in lapidary arts for polished stones, cabochons, beads, small carvings, and decorative architectural items.
Geological facts
First discovered in the Unaka Mountains of North Carolina, from which it derives its distinct trade name.
Field identification & locations
Easily identified by its mottled pattern of green epidote and pink feldspar. Commonly sourced from the US, South Africa, and Brazil.
