Pink granite (probable)
Granite; primarily quartz, potassium feldspar, plagioclase, and minor mica
AI-generated identification · may be incorrectCoarse-grained, pink-and-white, dull to slightly glassy; hardness about 6–7 Mohs, massive structure, with no obvious cleavage as a whole rock. The pink color commonly comes from potassium feldspar.

Physical properties
Coarse-grained, pink-and-white, dull to slightly glassy; hardness about 6–7 Mohs, massive structure, with no obvious cleavage as a whole rock. The pink color commonly comes from potassium feldspar.
Formation & geological history
An intrusive felsic igneous rock that crystallized slowly from magma deep in the continental crust, typically during ancient Precambrian to younger continental events. Exact age cannot be determined from the photograph.
Uses & applications
Used extensively as dimension stone, countertops, monuments, paving, aggregate, and decorative specimens; small pieces generally have little jewelry value.
Geological facts
The specimen appears irregular and possibly weathered or broken, so pink pegmatite or feldspar-rich rock is also possible. Grain size and mineral proportions would be clearer under magnification.
Field identification & locations
Look for visible interlocking quartz and feldspar grains, pink potassium feldspar, gray or white quartz, and scattered black mica. Common worldwide, especially in continental mountain belts and shield regions.
