Tumbled pink feldspar or rhodonite-like stone

Most likely potassium feldspar (orthoclase/microcline), KAlSi₃O₈; possibly rhodonite, MnSiO₃

AI-generated identification · may be incorrect

Small, roughly tumbled opaque pink-purple specimen with a dull to slightly vitreous luster and blocky shape. Feldspar hardness is Mohs 6–6.5 with two cleavages; rhodonite is softer, Mohs 5.5–6.5, and commonly shows black manganese-oxide veining, not clearly visible here.

Physical properties

Formation & geological history

Feldspar crystallizes in cooling silica-rich igneous rocks such as granite and pegmatite; rhodonite forms in manganese-rich metamorphic deposits. The specimen is likely naturally ancient but has been mechanically shaped or tumbled.

Uses & applications

Used mainly as a decorative or inexpensive lapidary stone; feldspar is also important in ceramics and glass, while rhodonite is used for carvings and ornamental objects.

Geological facts

The image is insufficient for confident species identification; color and shape alone cannot distinguish pink feldspar from rhodonite, dyed quartz, or another ornamental stone.

Field identification & locations

Check for feldspar cleavage and a glass-scratch test (feldspar can scratch ordinary glass); rhodonite often has black veining and may react weakly to acid if heavily altered. Common sources include India, Madagascar, Brazil, and the United States.
