Physical properties

Hardness 3.5 to 4 on the Mohs scale, pale pink to white color, vitreous to resinous luster, orthorhombic crystal structure, specific gravity 2.95.

Formation & geological history

Formed through biological and physical processes, often in marine environments, cave deposits, or hot springs.

Uses & applications

Used in ornamental carvings, jewelry, and by collectors. Also historically a source of calcium carbonate.

Geological facts

Aragonite forms the skeletons of many marine organisms, such as corals and mollusks. Over geologic time, it often alters to calcite.

Field identification & locations

Identified by its relatively low hardness and effervescence in cold dilute hydrochloric acid. Commonly found in Spain, Morocco, and various locations worldwide.
