Possible pink feldspar pebble

Likely potassium feldspar (orthoclase or microcline; KAlSi₃O₈)

AI-generated identification · may be incorrect

Small, rounded pink-to-salmon specimen with a dull to slightly glassy surface and darker inclusions. Feldspar has Mohs hardness 6, a monoclinic or triclinic crystal structure, two cleavages near 90°, and specific gravity around 2.6; the photo alone cannot confirm the identification.

Physical properties

Formation & geological history

Feldspar commonly crystallizes as magma cools in granite and related igneous rocks, formed over a wide range of geological ages. Weathering and transport can round fragments into pebbles.

Uses & applications

Feldspar is used in ceramics and glass; attractive pieces may be collected or used decoratively.

Geological facts

Potassium feldspar is a major component of many granites and can display pink, salmon, cream, or white colors.

Field identification & locations

The pink color and pebble shape fit feldspar, but a close-up or hardness/cleavage tests would help distinguish it from other rocks. Feldspar is common in granitic terrains worldwide.
