Turquoise-style beaded bracelet

Turquoise, hydrated copper–aluminum phosphate: CuAl₆(PO₄)₄(OH)₈·4H₂O; possibly dyed or composite beads

AI-generated identification · may be incorrect

Blue-green to green, commonly waxy to dull luster with dark brown/black matrix; microcrystalline, opaque, and typically Mohs hardness 5–6, specific gravity about 2.6–2.9. The rounded, polished beads are processed geological material; exact identity cannot be confirmed from the image alone.

Physical properties

Formation & geological history

Natural turquoise forms as a secondary mineral in arid, copper-rich, aluminum/phosphate-bearing rocks, often by alteration near oxidized copper deposits. Deposits are generally geologically young relative to their host rocks, commonly associated with volcanic or sedimentary environments.

Uses & applications

Used for jewelry, ornament, carvings, and collectible specimens. Common commercial beads may be stabilized with resin, reconstituted, dyed, or made from imitation materials.

Geological facts

Color and dark matrix resemble turquoise, but green coloration can also indicate variscite, chrysocolla, serpentine, or dyed howlite/magnesite. Avoid destructive testing on jewelry.

Field identification & locations

Common sources include Iran, the southwestern United States, China, Chile, and Mexico. Check for natural irregular matrix, waxy feel, moderate hardness, and copper reactions only with professional testing; plastic feels lighter and glass is harder and more vitreous.
