Polished turquoise matrix beads

Turquoise, CuAl₆(PO₄)₄(OH)₈·4H₂O, with host-rock matrix; exact identification is uncertain from the image

AI-generated identification · may be incorrect

Opaque blue-green patches with brown matrix, polished surface, and irregular brecciated pattern. Turquoise is a hydrated phosphate, typically Mohs 5–6, with a waxy to dull luster and triclinic crystal structure; bead polish obscures natural texture.

AI Estimated Value

Approximately $5–$50 for a small strand of common or treated beads; natural, high-quality turquoise can be worth substantially more.

Physical properties

Formation & geological history

Turquoise forms when copper-bearing fluids alter aluminum- and phosphorus-rich rocks, commonly in arid-zone fractures and cavities. Deposits are generally geologically young relative to their host rocks; the image cannot establish the source or age.

Uses & applications

Used primarily for jewelry and decorative beads; quality depends on color, pattern, stability, and whether the material is natural, stabilized, or treated.

Geological facts

The brown webbing may be host-rock matrix, but similar patterns can also occur in treated or composite material; appearance alone cannot confirm authenticity.

Field identification & locations

Turquoise is found in regions including the southwestern United States, Iran, China, and Mexico. Field identification uses blue-green color, relatively low hardness, and matrix pattern; gemological testing is needed to distinguish imitations and treatments.
