Physical properties

Formation & geological history

Forms as iron-colored chalcedony in silica-rich cavities and veins, commonly in volcanic rocks; its age depends on the host deposit. Natural carnelian occurs worldwide, including India, Brazil, Uruguay, and Madagascar.

Uses & applications

Used for beads, cabochons, and ornamental objects; historically valued for seals and jewelry.

Geological facts

Carnelian’s orange color is chiefly associated with iron impurities; heating can deepen or alter the color of chalcedony.

Field identification & locations

Identify by its orange color, waxy translucence, and hardness; a glass scratch test is not conclusive. The photo shows a small polished bead, so its exact natural color and treatment cannot be determined visually.
