Physical properties

Formation & geological history

Natural turquoise forms as a secondary copper phosphate in weathered, copper-rich rocks, commonly in arid zones. Deposits range from geologically recent weathering to ancient host-rock mineralization; the pictured stone’s natural or synthetic origin is unknown.

Uses & applications

Turquoise is used in jewelry and ornamental objects; imitations are also common.

Geological facts

Color and veining alone cannot reliably distinguish natural turquoise from dyed minerals, composites, or glass.

Field identification & locations

A gemologist can assess it using magnification and appropriate tests; avoid destructive scratch tests. Not enough detail is visible to identify a deposit or confirm the material.
