Physical properties

Formation & geological history

Formed through hydrothermal alteration (metasomatism) of granite, where plagioclase feldspar is replaced by epidote. Often associated with orogenic belts and granite intrusions.

Uses & applications

Used primarily for ornamental purposes, carved into cabochons, beads, spheres, and tumbled stones for jewelry and decorative objects.

Geological facts

Unakite was first discovered in the Unaka Mountains of North Carolina, from which it gets its name. It is a popular lapidary material due to its striking pink and green contrast.

Field identification & locations

Easily identified visually by its distinctive speckled mosaic of green epidote and pink orthoclase feldspar. Commonly found in glacial drift derived from granite regions, as well as in the Blue Ridge Mountains of the USA, South Africa, Brazil, and China.
