Physical properties

Formation & geological history

Carnelian forms when silica-rich fluids deposit chalcedony, often filling cavities in volcanic rocks; its orange color commonly comes from iron oxides. Deposits occur in many ages and regions, including India, Brazil, Uruguay, and Madagascar.

Uses & applications

Used for beads, cabochons, and decorative jewelry since antiquity; these earrings’ value depends on stone quality, workmanship, and the metal.

Geological facts

Carnelian is a chalcedony variety, not a separate mineral species; historical examples were used for seals and carved ornaments.

Field identification & locations

Identify by its orange-red color, translucency, and hardness; confirmatory testing would require examining the stones directly. The image does not establish whether these are natural carnelian or a similar dyed material.
