Small feldspar-rich rock fragment, possibly granite or pegmatite
Likely quartz–feldspar aggregate; exact identification is uncertain from the small, pale fragment
AI-generated identification · may be incorrectCream to pale pink, granular and opaque with a dull luster; visible grains may include feldspar and quartz. Hardness and crystal structure cannot be reliably determined from the image.

Physical properties
Cream to pale pink, granular and opaque with a dull luster; visible grains may include feldspar and quartz. Hardness and crystal structure cannot be reliably determined from the image.
Formation & geological history
If granite or pegmatite, it formed as silica-rich magma cooled slowly underground; such rocks range widely in age and occur in continental crust.
Uses & applications
Comparable material is used as building and dimension stone, aggregate, and decorative stone; this tiny fragment has little practical or jewelry value.
Geological facts
The image shows a small, roughly cuboid, pale granular piece, but not enough diagnostic detail to distinguish a rock from a single mineral or identify it confidently.
Field identification & locations
Check for interlocking grains and test hardness on an inconspicuous edge; feldspar commonly cleaves, while quartz does not. Similar rocks occur worldwide in granitic terrains.
