Pink feldspar-rich granite pebble
Granite, likely quartz–feldspar dominated
AI-generated identification · may be incorrectRounded, pale pink and cream with a granular, mottled texture; likely quartz and potassium feldspar with minor mica. Typical granite hardness is about 6–7 Mohs, with a vitreous-to-dull luster and interlocking crystals; the image does not show enough detail to confirm minerals or exact properties.

Physical properties
Rounded, pale pink and cream with a granular, mottled texture; likely quartz and potassium feldspar with minor mica. Typical granite hardness is about 6–7 Mohs, with a vitreous-to-dull luster and interlocking crystals; the image does not show enough detail to confirm minerals or exact properties.
Formation & geological history
Granite forms when silica-rich magma cools slowly underground, allowing coarse crystals to grow. Its age depends on the source outcrop and cannot be determined from the pebble alone.
Uses & applications
Granite is widely used as dimension stone, paving, countertops, and aggregate; this small pebble is mainly suitable for collecting or decoration.
Geological facts
Pink coloration commonly comes from potassium feldspar, while pale translucent grains may be quartz.
Field identification & locations
The rounded shape suggests transport by water or glacial action. Look for distinct interlocking grains and, with magnification, glassy quartz and pink feldspar; common source regions include granitic terrains worldwide.
