Pink granite or granitic pegmatite
Felsic intrusive rock dominated by quartz, feldspar, and minor mica; exact identification requires a fresh surface or testing.
AI-generated identification · may be incorrectCoarse, crystalline texture with pale pink feldspar, whitish quartz, and possible dark mica; typically Mohs 6–7, vitreous to dull luster, no strong cleavage as a rock, and specific gravity about 2.6–2.7.

Physical properties
Coarse, crystalline texture with pale pink feldspar, whitish quartz, and possible dark mica; typically Mohs 6–7, vitreous to dull luster, no strong cleavage as a rock, and specific gravity about 2.6–2.7.
Formation & geological history
Formed when silica-rich magma cooled slowly deep underground, allowing large crystals to grow, generally during Precambrian to Phanerozoic intrusive events.
Uses & applications
Used extensively as building stone, countertops, monuments, aggregate, and landscaping rock; attractive pieces may be sold as educational or decorative specimens.
Geological facts
The pink color usually comes from potassium feldspar, while darker patches commonly represent biotite or hornblende. The specimen appears weathered and may also be a feldspar-rich granite or pegmatite.
Field identification & locations
Common in continental mountain belts and exposed plutons worldwide, including the United States, Canada, Brazil, India, and Scandinavia. Identify it by visible interlocking quartz and feldspar crystals; a glassy quartz grain and scratch resistance help confirm it.
