Polished pink feldspar-rich rock, possibly unakite

Likely unakite (epidote, pink potassium feldspar, and quartz); identification is uncertain from the photo

AI-generated identification · may be incorrect

Opaque, mottled salmon-pink and pale green-gray, with a granular texture and subdued polish. Unakite’s minerals are typically Mohs 6–7; individual crystal structure and cleavage vary by mineral.

Physical properties

Opaque, mottled salmon-pink and pale green-gray, with a granular texture and subdued polish. Unakite’s minerals are typically Mohs 6–7; individual crystal structure and cleavage vary by mineral.

Formation & geological history

Unakite forms when granite is altered by hydrothermal fluids, converting some minerals to green epidote while feldspar remains pink. It is associated with ancient crystalline basement rocks; the specimen’s age and exact composition cannot be determined visually.

Uses & applications

Commonly sold as a decorative or collecting stone and used for carvings, beads, and cabochons; it has little industrial value.

Geological facts

The name unakite comes from the Unaka Mountains of the southeastern United States, where it was first described.

Field identification & locations

Look for a distinctive mottled mixture of pink feldspar and green epidote, often with quartz; confirm with a close view of the mineral grains. Unakite is known from the Appalachians and occurs elsewhere in altered granitic rocks.
