Physical properties

Formation & geological history

Natural turquoise forms in arid-zone, near-surface oxidation zones of copper deposits, commonly over geological timescales of millions of years; bead processing and possible dyeing are later human treatments.

Uses & applications

Used in jewelry and ornamental objects; turquoise is also valued in lapidary collecting.

Geological facts

Turquoise has been used in jewelry and decorative art for thousands of years. Strongly uniform color and repeated vein patterns can occur in dyed or manufactured imitations.

Field identification & locations

Common sources of natural turquoise include Iran, the southwestern United States, China, and Mexico. Check for color concentrated in cracks or unusually uniform appearance; definitive identification may require gemological testing.
