Tumbled yellow-orange stone, possibly carnelian

Uncertain from the image; possibly chalcedony (microcrystalline SiO₂)

AI-generated identification · may be incorrect

Smooth, rounded, opaque-to-translucent golden orange with a waxy luster. If carnelian, hardness is about 6.5–7 Mohs and its crystal structure is trigonal, though too little detail is visible to confirm identification.

Physical properties

Formation & geological history

A tumbled specimen may have been mechanically polished. Carnelian forms when silica-rich fluids deposit chalcedony in cavities and fractures; the image does not establish its age or origin.

Uses & applications

Tumbled stones are used in jewelry, crafts, and collections; confirmed carnelian is also cut into beads and cabochons.

Geological facts

Carnelian’s orange-red color is commonly associated with iron impurities in chalcedony.

Field identification & locations

The rounded shape and polish indicate processing, but color alone cannot distinguish carnelian from other stones or glass. A hardness test and examination under magnification would help identify it.
