Pink potassium feldspar-rich granite pegmatite

Feldspar-dominant granitic pegmatite, chiefly orthoclase or microcline (KAlSi₃O₈), with possible quartz and mica

AI-generated identification · may be incorrect

Coarse, uneven interlocking grains; salmon-pink to cream, with a vitreous-to-pearly luster. Feldspar hardness is about 6 Mohs, with two near-right-angle cleavage directions; exact mineral proportions cannot be confirmed from the photo.

Physical properties

Coarse, uneven interlocking grains; salmon-pink to cream, with a vitreous-to-pearly luster. Feldspar hardness is about 6 Mohs, with two near-right-angle cleavage directions; exact mineral proportions cannot be confirmed from the photo.

Formation & geological history

Likely crystallized slowly from silica-rich magma, potentially in a late-stage pegmatite vein; its age depends on the source deposit and cannot be determined visually.

Uses & applications

Feldspar is used in ceramics and glass; attractive pieces may be kept as hand specimens or used decoratively.

Geological facts

The blocky pink grains and pale, sparkly patches are consistent with feldspar-rich material, though a close-up or mineral tests would be needed to identify accompanying minerals.

Field identification & locations

Look for salmon-pink color, blocky cleavage faces, and a coarse crystalline texture; granitic pegmatites occur worldwide. Approximate value: $2–$20 for a common hand specimen, depending on size and appearance.
