Small granite pebble
Granite, chiefly quartz, feldspar, and dark mica or amphibole
AI-generated identification · may be incorrectCoarse, mottled pale pink/cream and dark grains; likely Mohs 6–7, vitreous quartz with duller feldspar, and no prominent cleavage in the whole pebble. The photo is too small to confirm mineral grains or identify it conclusively.

Physical properties
Coarse, mottled pale pink/cream and dark grains; likely Mohs 6–7, vitreous quartz with duller feldspar, and no prominent cleavage in the whole pebble. The photo is too small to confirm mineral grains or identify it conclusively.
Formation & geological history
Granite forms when silica-rich magma cools slowly underground, allowing visible crystals to grow; such rocks occur in Precambrian and younger continental crust.
Uses & applications
Granite is widely used as dimension stone, paving, countertops, and aggregate; this tiny rounded piece has negligible commercial value.
Geological facts
The pebble’s rounded shape suggests abrasion during transport by water, ice, or sediment movement.
Field identification & locations
Look for interlocking light quartz/feldspar grains and scattered dark minerals; granite is common in continental mountain belts worldwide. Estimated value: under $1 as an ordinary pebble.
