Likely potassium feldspar (orthoclase) fragment

Orthoclase, KAlSi₃O₈ (tentative identification)

AI-generated identification · may be incorrect

Small, rough cream-white fragment with salmon-pink/orange staining; feldspar is typically Mohs 6, vitreous to pearly, monoclinic, with two cleavages near 90°. The photo alone cannot confirm mineral identity or specific gravity.

Physical properties

Formation & geological history

If feldspar, it crystallized from silica-rich magma in granite or pegmatite, or occurs in metamorphic rock; such host rocks range from ancient to geologically recent.

Uses & applications

Feldspar is used in glass and ceramics; attractive, clean pieces may be cut as gemstones, though this fragment appears too small and rough for typical jewelry use.

Geological facts

Pink coloration commonly comes from trace impurities in potassium feldspar, while rusty surface patches may be iron staining.

Field identification & locations

Look for blocky shape, two nearly perpendicular cleavage faces, and hardness sufficient to scratch glass; common in granites and pegmatites worldwide. A hand specimen or hardness/cleavage tests would help verify the identification.
