Carnelian (likely)

Orange chalcedony, a microcrystalline variety of quartz (SiO₂)

AI-generated identification · may be incorrect

The ring holds a polished, translucent orange-red cabochon with a vitreous-to-waxy luster. Quartz hardness is 7 Mohs; crystals are microscopic, with no visible cleavage and conchoidal fracture. The image cannot confirm the stone or distinguish natural carnelian from dyed chalcedony or glass.

Physical properties

Formation & geological history

Chalcedony forms as silica precipitates in cavities and veins, commonly in volcanic rocks; iron oxides produce its orange-red color. Its formation age depends on the deposit and cannot be determined from the photograph.

Uses & applications

Used for cabochons, rings, beads, seals, and ornamental objects; chalcedony is also collected as a lapidary material.

Geological facts

Carnelian has been carved into seals and jewelry since antiquity. Its color can be enhanced by heating, and similar-looking stones may be dyed.

Field identification & locations

The smooth orange cabochon and polished finish are consistent with carnelian, but visual identification alone is uncertain. Carnelian occurs worldwide, notably in India, Brazil, Uruguay, and Madagascar; hardness testing or gemological examination can help verify it.
