Physical properties
Light pink-beige, granular and massive with a rough weathered surface; likely Mohs hardness 6–7, vitreous to dull luster, interlocking crystalline texture, and no obvious cleavage on the broken faces.
Formation & geological history
Formed by slow cooling of silica-rich magma underground, producing coarse crystals; commonly Precambrian to Phanerozoic in age. The surface appears naturally weathered or possibly cut.
Uses & applications
Used extensively as dimension stone, countertops, monuments, aggregate, and decorative rock; small unattractive fragments have little jewelry value.
Geological facts
The pink color typically comes from potassium feldspar, while darker specks may be biotite or amphibole. Exact identification is limited because the specimen is small and the image lacks a fresh crystalline surface.
Field identification & locations
Common in continental crust and found worldwide, especially in granite quarries and glacial deposits. A glassy gray quartz grain, pink feldspar, and occasional black mica would support the identification; acid testing should show no fizz.
