Pink granite or pink feldspathic rock
Granite, chiefly quartz, potassium feldspar, and plagioclase; exact identification is uncertain from the image
AI-generated identification · may be incorrectPale salmon-pink, massive, dull to weakly granular, with possible feldspar and quartz grains; typical granite hardness is about 6–7 Mohs, non-cleaving as a rock, and specific gravity about 2.63–2.75.

Physical properties
Pale salmon-pink, massive, dull to weakly granular, with possible feldspar and quartz grains; typical granite hardness is about 6–7 Mohs, non-cleaving as a rock, and specific gravity about 2.63–2.75.
Formation & geological history
Granite forms when silica-rich magma cools slowly deep underground, producing interlocking crystals; specimens may range from Precambrian to much younger ages depending on locality.
Uses & applications
Used extensively as building stone, countertops, monuments, aggregate, and decorative material; this small piece has mainly educational or modest collecting value.
Geological facts
The pink color commonly comes from potassium feldspar, while darker patches may represent biotite or amphibole. The image does not show enough detail to confirm granite versus pink quartzite or another feldspathic rock.
Field identification & locations
Look for visible interlocking crystals, pink feldspar, gray or glassy quartz, and occasional black mica; a glass-scratch test can help assess hardness, but professional identification may require a hand lens or thin section. Common worldwide.
