Physical properties

Hardness 6.5–7 Mohs; peach-orange, translucent to opaque, waxy-to-glassy luster, cryptocrystalline quartz with no visible cleavage. The specimen is polished and wire-wrapped in metal.

Formation & geological history

Silica-rich groundwater deposited quartz fibers in cavities or fractures, commonly in volcanic rocks; coloration generally comes from iron oxides. Chalcedony forms across many geological ages, often in Cenozoic volcanic environments.

Uses & applications

Used for cabochons, pendants, beads, carvings, and ornamental objects; durable and affordable jewelry material.

Geological facts

Carnelian is typically uniformly orange-red, while agate shows banding or contrasting zones; the visible subtle zoning may indicate agate/chalcedony rather than solid carnelian.

Field identification & locations

Common sources include Brazil, Uruguay, India, Madagascar, Germany, and the western United States. Identify by its waxy appearance, translucency, hardness, and lack of cleavage; glass imitations may show bubbles or scratch more easily.
