Pink granite, likely weathered and water-worn
Felsic granitoid; primarily quartz, potassium feldspar, plagioclase, and minor biotite/hornblende
AI-generated identification · may be incorrectHardness about 6–7 Mohs; salmon-pink, fine-to-medium granular texture with dark mafic inclusions, dull to weakly vitreous luster, and no prominent cleavage as a whole. The rounded shape indicates natural abrasion or tumbling; surface pits may reflect weathered mafic grains.

Physical properties
Hardness about 6–7 Mohs; salmon-pink, fine-to-medium granular texture with dark mafic inclusions, dull to weakly vitreous luster, and no prominent cleavage as a whole. The rounded shape indicates natural abrasion or tumbling; surface pits may reflect weathered mafic grains.
Formation & geological history
Crystallized slowly from silica-rich magma deep in the continental crust, commonly during Precambrian to Phanerozoic mountain-building events, then exposed by uplift and erosion. Its rounded form likely developed in a stream, beach, or glacial environment.
Uses & applications
Used as dimension stone, countertops, monuments, aggregate, landscaping stone, and decorative specimens; generally not jewelry grade.
Geological facts
Pink color commonly comes from potassium feldspar, while black spots are biotite or amphibole. A fresh broken surface should reveal clearly interlocking visible crystals.
Field identification & locations
Common in continental shields and mountain belts worldwide, including Scandinavia, New England, the Canadian Shield, India, and Australia. Confirm with a glass-scratch test and visible quartz/feldspar grains; exact identification is limited by the weathered surface.
