Physical properties
Salmon-pink to cream, vitreous to pearly luster; Mohs hardness 6, blocky crystals with two near-90° cleavage directions. The specimen appears coarse and feldspar-rich, though identification from the photo is uncertain.
Formation & geological history
Potassium feldspar crystallizes from silica-rich magma, commonly in granite and pegmatite; such rocks form across a wide range of geologic ages.
Uses & applications
Used in ceramics and glass as a flux; attractive crystals and polished material are collected and sometimes used decoratively.
Geological facts
Pink color commonly comes from trace impurities in potassium feldspar, rather than from a separate pink mineral.
Field identification & locations
Look for a salmon-pink color, blocky shape, and two cleavage planes near right angles; common in granites and pegmatites worldwide. A small, rough specimen like this is typically worth about $1–$10 USD.
