Physical properties

Formation & geological history

Turquoise forms as a secondary mineral in arid, oxidized copper deposits, commonly replacing aluminum-rich host rock. Deposits are generally geologically young relative to their host rocks, often associated with Cenozoic weathering and hydrothermal alteration.

Uses & applications

Used extensively for cabochon jewelry, carvings, beads, and ornamental objects; the ring setting appears designed for jewelry rather than industrial use.

Geological facts

Blue color comes mainly from copper, while green tones reflect iron or dehydration. Spiderweb matrix may be natural host rock, though dyed or reconstructed turquoise can look similar.

Field identification & locations

Field identification uses its opaque blue-green color, low-to-moderate hardness, waxy surface, and copper-stained geological matrix; avoid relying on color alone because imitations are common. Major sources include Iran, Arizona and Nevada, China, Mexico, and Chile.
