Peach-colored feldspar fragment

Likely potassium feldspar (orthoclase or microcline; KAlSi₃O₈)

AI-generated identification · may be incorrect

Small, pale peach to cream, translucent fragment with a vitreous-to-pearly luster and apparent cleavage surfaces. Feldspar hardness is about 6 on the Mohs scale; crystal structure is monoclinic or triclinic, and specific gravity is about 2.5–2.6.

Physical properties

Small, pale peach to cream, translucent fragment with a vitreous-to-pearly luster and apparent cleavage surfaces. Feldspar hardness is about 6 on the Mohs scale; crystal structure is monoclinic or triclinic, and specific gravity is about 2.5–2.6.

Formation & geological history

Feldspar crystallizes in igneous rocks such as granite and pegmatite, and occurs in metamorphic rocks; it formed over geologic time as silicate magma cooled. The image does not establish its precise source or age.

Uses & applications

Feldspar is widely used in glass and ceramic production; attractive, clear varieties are sometimes cut as gemstones. This tiny, rough fragment has little apparent commercial value.

Geological facts

Feldspar is the most abundant mineral group in Earth’s crust and commonly weathers into clay minerals.

Field identification & locations

The peach color and blocky-looking cleavage suggest feldspar, but the tiny specimen cannot be identified confidently from the image alone. Check for two cleavage directions near 90° and hardness near 6; feldspar is common in granites and pegmatites worldwide.
