Green cabochon gemstone pendant

Indeterminate; likely dyed green turquoise, chrysoprase, or opaque beryl set with blue/clear accent stones

AI-generated identification · may be incorrect

The central stone is polished, opaque-to-translucent green with a vitreous/waxy luster and no visible crystal faces; exact hardness and cleavage cannot be determined photographically. The surrounding blue and lower gray stones may be glass, cubic zirconia, or additional gemstones, and the metal setting is non-geologica…

Physical properties

Formation & geological history

The central material could represent natural turquoise (hydrous copper aluminum phosphate), chrysoprase (nickel-bearing chalcedony), or another green gemstone; formation age and locality cannot be established without testing. It has been cut and polished into a cabochon.

Uses & applications

Used as jewelry and ornamental material. Value depends mainly on stone identity, naturalness, treatment, metal purity, workmanship, and provenance.

Geological facts

Strong color uniformity and the absence of diagnostic matrix make dyed or treated material possible. A refractive-index, specific-gravity, hardness, magnification, and UV test would help distinguish candidates.

Field identification & locations

Inspect for matrix, dye concentration in cracks, bubbles, or color rubbing off; turquoise is softer (Mohs 5–6), chrysoprase harder (about 6.5–7). Common sources include Iran/China/USA for turquoise and Australia/Brazil/Poland for chrysoprase.
