Physical properties

Formation & geological history

Natural turquoise forms through near-surface alteration of copper-bearing rocks in arid climates; deposits range in age from ancient geological formations to much younger weathering zones. Beads are cut and polished, often with stabilization to improve durability.

Uses & applications

Used in jewelry and ornamental objects; historically valued in many cultures. Stabilized turquoise is common in affordable bead jewelry.

Geological facts

Turquoise’s blue color comes mainly from copper, while iron can contribute green hues. Dark matrix veining may be natural host rock, but bead appearance alone does not establish authenticity.

Field identification & locations

Common deposits include Iran, the southwestern United States, China, and Mexico. Check for consistent color, natural-looking matrix, and reputable testing; dyed howlite or other imitations can resemble turquoise.
