Physical properties

Formation & geological history

Turquoise forms as a secondary mineral in arid-zone weathering deposits, typically where copper-bearing rocks interact with phosphate- and aluminum-rich water. Deposits occur in rocks of many ages.

Uses & applications

Used mainly for jewelry and decorative objects; turquoise is also collected as a gemstone.

Geological facts

The gold-colored fittings are likely metal and are not part of the geological specimen. Turquoise color varies with copper and iron content.

Field identification & locations

Natural turquoise is relatively soft and opaque, often with matrix veining; confirm identity and treatment through a reputable gem laboratory or seller. Major sources include Iran, the southwestern United States, China, and Mexico.
