Likely weathered granite or granitic pegmatite fragment
Granite/granitoid, chiefly quartz (SiO₂), feldspar, and mica
AI-generated identification · may be incorrectSmall irregular fragment with pale pink-beige feldspar, translucent gray quartz, and possible dark mica; granular texture and dull-to-glassy luster. Typical granite hardness is about 6–7 Mohs, with no obvious cleavage as a whole rock and specific gravity near 2.6–2.7.

Physical properties
Small irregular fragment with pale pink-beige feldspar, translucent gray quartz, and possible dark mica; granular texture and dull-to-glassy luster. Typical granite hardness is about 6–7 Mohs, with no obvious cleavage as a whole rock and specific gravity near 2.6–2.7.
Formation & geological history
Formed by slow crystallization of silica-rich magma deep in the crust, commonly during Precambrian to Phanerozoic continental plutonism; surface weathering produced the rounded, stained exterior.
Uses & applications
Granite is widely used as dimension stone, countertops, aggregate, monuments, and building material; this tiny fragment has mainly educational or collector value.
Geological facts
The pink coloration commonly reflects potassium feldspar, while rusty brown areas are likely iron-oxide weathering products. The photograph is insufficient for a definitive identification or age determination.
Field identification & locations
Look for interlocking visible grains of quartz, feldspar, and mica; a knife should not scratch fresh quartz-rich surfaces. Common worldwide, especially in continental shields and mountain belts.
