Likely feldspar (rough specimen)

Probably potassium feldspar, KAlSi₃O₈; exact identification is uncertain from the image

AI-generated identification · may be incorrect

Creamy white to pale tan, opaque, with a dull-to-pearly luster and blocky cleavage surfaces. Feldspar hardness is about 6 on the Mohs scale; crystals are monoclinic or triclinic depending on species.

Physical properties

Creamy white to pale tan, opaque, with a dull-to-pearly luster and blocky cleavage surfaces. Feldspar hardness is about 6 on the Mohs scale; crystals are monoclinic or triclinic depending on species.

Formation & geological history

Feldspars crystallize in many igneous rocks and also occur in metamorphic rocks; they formed throughout geologic time as silicate melts cooled or rocks recrystallized.

Uses & applications

Feldspar is widely used in glass and ceramic manufacturing; attractive varieties are collected or occasionally cut as gemstones.

Geological facts

Feldspar is the most abundant mineral group in Earth’s crust.

Field identification & locations

The pale color and apparent blocky cleavage are consistent with feldspar, but the image alone cannot distinguish it reliably from other pale minerals. Check hardness and cleavage, or consult a mineral identification specialist.
