Pink-and-green mineral specimen, possibly unakite

Unakite, an epidote–feldspar–quartz rock; identification is uncertain from the photo

AI-generated identification · may be incorrect

Rough, mottled pink and green with a granular appearance. Unakite commonly contains pink orthoclase feldspar (Mohs 6), green epidote (6–7), and quartz (7); the photo is too small to confirm luster, cleavage, or composition.

Physical properties

Formation & geological history

Unakite forms when granite or related rock is altered by metamorphism and hydrothermal fluids. Its age depends on the source rocks and cannot be determined visually.

Uses & applications

Commonly used for polished ornaments, beads, and lapidary crafts; this small rough piece is primarily a collector specimen.

Geological facts

The name comes from the Unaka Mountains of North Carolina, where the rock was first described.

Field identification & locations

Look for a coarse, intergrown pattern of salmon-pink feldspar and pistachio-green epidote, often with quartz. Similar colors alone are not diagnostic, so a closer view or mineral tests would be needed to confirm it.
