Polished pink feldspar or quartz pebble (uncertain)

Likely microcline feldspar (KAlSi₃O₈) or quartz (SiO₂), with iron-oxide inclusions

AI-generated identification · may be incorrect

Small polished, opaque-to-translucent salmon-pink stone with black or dark red inclusions and a vitreous-to-waxy luster. Likely hardness Mohs 6–7; cleavage is not visible because the specimen is polished.

Physical properties

Formation & geological history

Probably formed in a granitic or pegmatitic environment, where feldspar or quartz crystallized from cooling magma and acquired iron-oxide inclusions; its precise geological age and locality cannot be determined from the image.

Uses & applications

Suitable for a small cabochon, tumbled stone, or mineral collection; similar material is used in ornamental stone and inexpensive jewelry.

Geological facts

The strong pink-red coloration may result from hematite or other iron oxides. Image-only identification is limited because polishing obscures crystal faces and diagnostic cleavage.

Field identification & locations

Test hardness against glass and inspect streak, translucency, and cleavage: feldspar commonly shows two cleavage directions, while quartz has conchoidal fracture and no cleavage. Common sources include granite pegmatites in Brazil, Madagascar, India, and the United States.
