Dyed turquoise-like gemstone beads

Likely turquoise (hydrous copper aluminum phosphate, CuAl₆(PO₄)₄(OH)₈·4H₂O), possibly dyed howlite or magnesite

AI-generated identification · may be incorrect

Opaque blue-green, polished, waxy-to-vitreous luster; turquoise is triclinic, Mohs hardness 5–6, specific gravity about 2.6–2.9, with poor cleavage. Dark veining and unusually uniform color may indicate dyed howlite/magnesite or stabilized turquoise.

Physical properties

Formation & geological history

Natural turquoise forms as a secondary phosphate mineral in arid, copper-rich weathering zones, commonly millions of years old; notable deposits occur in Iran, the southwestern United States, China, and Mexico. Beads are cut and polished, often stabilized with resin or dyed.

Uses & applications

Used primarily in jewelry and ornamental carving; lower-grade or imitation material is common in inexpensive bracelets and beads. Quality natural turquoise has greater collector value than treated or imitation material.

Geological facts

Turquoise color ranges from sky blue to green depending on copper, iron, and zinc content. Howlite and magnesite commonly have gray-black veining and are dyed blue to imitate turquoise.

Field identification & locations

Check for natural irregular matrix, hardness, and a cool waxy feel; glassy luster, perfectly uniform color, or color concentrated in cracks suggests dye or imitation. A gemological test is needed for certainty.
