Uncertain from the image; possibly potassium feldspar (orthoclase/microcline) with quartz
AI-generated identification · may be incorrectPale peach to cream, opaque, unevenly fractured, with a dull to slightly vitreous luster. Individual crystals and cleavage are not clear enough to confirm; feldspar hardness is about 6 Mohs.

Physical properties
Pale peach to cream, opaque, unevenly fractured, with a dull to slightly vitreous luster. Individual crystals and cleavage are not clear enough to confirm; feldspar hardness is about 6 Mohs.
Formation & geological history
If feldspar-rich igneous rock, it crystallized slowly from silica-rich magma, commonly in granite or pegmatite. The specimen’s age and exact formation cannot be determined visually.
Uses & applications
Granite is used as construction and decorative stone; feldspar is used in ceramics and glass. This small, unidentified fragment has little commercial value.
Geological facts
The image does not show enough texture or scale to distinguish a feldspar crystal from a weathered rock fragment or other pale mineral.
Field identification & locations
A fresh feldspar surface commonly shows two near-right-angle cleavage planes and can scratch glass; granite should show multiple interlocking minerals. Common in continental crust and pegmatites worldwide.
