Turquoise beads (likely dyed howlite or magnesite imitation)

Turquoise: CuAl₆(PO₄)₄(OH)₈·4H₂O; the photographed material may instead be dyed CaMg(CO₃)₂ or MgCO₃

AI-generated identification · may be incorrect

Opaque blue-green beads with dark matrix-like veining and a polished surface. Natural turquoise has Mohs hardness 5–6 and a triclinic crystal structure; the image alone cannot confirm the beads’ material.

Physical properties

Formation & geological history

Turquoise forms as a secondary copper phosphate in arid-zone deposits, commonly in fractures and cavities of weathered, copper-bearing rocks. Deposits are generally geologically young relative to their host rocks; imitation beads may be dyed stone.

Uses & applications

Used in jewelry and ornamental objects; turquoise is also a longstanding decorative material in many cultures.

Geological facts

Regularly patterned dark veins and highly uniform color can occur in stabilized or imitation turquoise, including dyed howlite or magnesite.

Field identification & locations

Look for natural color variation and matrix, but appearance alone is inconclusive; gemological testing can distinguish turquoise from dyed substitutes. Major sources include the southwestern United States, Iran, China, and Tibet.
