Likely carnelian ring stone

Carnelian, orange-red variety of chalcedony (microcrystalline quartz, SiO₂)

AI-generated identification · may be incorrect

The ring appears to hold a polished, dark reddish-brown translucent-to-opaque cabochon; the photo does not reveal its internal texture, so identification is tentative. If carnelian: Mohs hardness 6.5–7, vitreous to waxy luster, trigonal quartz structure, no cleavage, and specific gravity about 2.6.

Physical properties

Formation & geological history

Carnelian forms when silica-rich fluids deposit chalcedony in rock cavities, commonly with iron impurities producing red-orange color. Such deposits occur in many ages and settings; the stone’s source and age cannot be determined from the image.

Uses & applications

Carnelian is used for cabochon jewelry, beads, and carvings; the pictured specimen is set in a metal ring.

Geological facts

Carnelian is a variety of chalcedony, not a separate mineral species. A dark stone like this could also be another gem or an imitation, and a photograph cannot confirm its identity.

Field identification & locations

Check for natural banding or uneven color and inspect under magnification; hardness or refractive-index testing by a jeweler can help distinguish it from glass or other stones. Carnelian is found worldwide, including India, Brazil, and Uruguay.
