Likely pink feldspar (orthoclase or microcline)

Potassium feldspar, KAlSi₃O₈

AI-generated identification · may be incorrect

Pale salmon-pink, opaque to slightly translucent, with a vitreous to pearly luster and blocky cleavage surfaces. Feldspar is Mohs 6; the photo does not show enough detail to confirm cleavage or distinguish it from other pink minerals.

Physical properties

Formation & geological history

Potassium feldspar crystallizes from silica-rich magma in granite and pegmatite, and also occurs in metamorphic rocks. Its age depends on its source rock and cannot be determined from the image.

Uses & applications

Used in glass and ceramic manufacture; attractive crystals are collected and occasionally cut as gemstones.

Geological facts

Pink color commonly comes from trace impurities. The specimen’s rough, blocky appearance is consistent with feldspar, but visual identification alone is uncertain.

Field identification & locations

Look for two cleavage directions meeting at nearly 90° and hardness sufficient to scratch glass; feldspar is common in granites and pegmatites worldwide. A definitive identification may require testing cleavage and hardness.
