Tumbled yellow-orange stone, possibly carnelian
Uncertain from the image; possibly chalcedony (microcrystalline SiO₂)
AI-generated identification · may be incorrectSmooth, 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
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.
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.
