Orange tumbled feldspar, likely sunstone

Probably potassium feldspar (orthoclase or microcline); identification is uncertain from the image

AI-generated identification · may be incorrect

Rounded, opaque orange-peach pebble with a dull to slightly waxy surface; feldspar hardness is about 6 on the Mohs scale, with two cleavage directions and a monoclinic or triclinic crystal structure. No diagnostic glitter or internal features are visible to confirm sunstone.

Physical properties

Formation & geological history

Feldspar crystallizes in igneous rocks, especially granites and pegmatites; the pebble may have been naturally worn or mechanically tumbled. Its geological age and source cannot be determined from the image.

Uses & applications

Feldspar is used in glass and ceramics; attractive sunstone and feldspar pieces are collected or made into beads and jewelry.

Geological facts

Sunstone is a feldspar variety whose characteristic shimmer comes from reflective inclusions, often copper or hematite; that effect is not evident here.

Field identification & locations

Check for feldspar cleavage and, if claiming sunstone, glittering aventurescence under directional light. Orange quartz, calcite, and dyed stone can look similar; a photo alone cannot confirm identity.
