Unakite (likely)

Epidote–feldspar–quartz rock, commonly called unakite; composition is uncertain from the photo.

AI-generated identification · may be incorrect

Mottled pink, greenish-gray, and dark patches with a rough, granular surface. Unakite typically contains pink potassium feldspar, green epidote, and quartz; hardness is about 6–7 Mohs, with vitreous to dull luster and no prominent cleavage as a whole rock.

Physical properties

Formation & geological history

Forms when granite is altered by hydrothermal fluids, converting some feldspar to epidote; commonly associated with older crystalline rocks, often Precambrian. A photo cannot establish the specimen’s age or confirm its mineral composition.

Uses & applications

Polished unakite is used for beads, cabochons, carvings, and decorative stone; rough pieces are mainly collected.

Geological facts

Unakite is named for the Unaka Mountains of the southeastern United States, where it was first described.

Field identification & locations

Look for the characteristic pink-and-green mottling; this specimen’s colors are muted and dark, so visual identification is tentative. Unakite is known from the Appalachians and other altered granites worldwide.
