Formation & geological history

Formed through the hydrothermal metamorphism of granite, where plagioclase feldspar is replaced by epidote. It is commonly associated with Precambrian formations.

Uses & applications

Primarily used for lapidary work including beads, cabochons, carvings, and tumbled stones. Occasional use as architectural trim.

Geological facts

Unakite was first discovered in the Unaka Range of the Blue Ridge Mountains in North Carolina, USA, from which it gets its name.

Field identification & locations

Identified by its distinctive 'pistachio and salmon' color scheme. Found in the United States, South Africa, and Brazil. Popular among collectors for its unique aesthetics and metaphysical associations with balance.
