Dyed green stone cabochon pendant

Likely dyed green aventurine quartz or chrysoprase; exact identification requires testing

AI-generated identification · may be incorrect

Polished opaque-to-translucent green cabochon with vitreous/waxy luster; likely hardness 6.5–7 (aventurine quartz) or 6–7 (chrysoprase), with no visible crystal faces. The intense, fairly uniform color suggests dyeing or enhancement.

Physical properties

Formation & geological history

If aventurine, it formed as quartz with abundant fuchsite or other mineral inclusions in metamorphic or hydrothermal environments; if chrysoprase, it is nickel-bearing chalcedony formed in weathered ultramafic rocks. Geological ages vary by deposit.

Uses & applications

Used as an inexpensive jewelry pendant, ornamental stone, and collector specimen; commonly sold in polished cabochon form.

Geological facts

Visual inspection cannot reliably distinguish dyed quartz, chrysoprase, dyed chalcedony, or glass. A gemological test for hardness, specific gravity, magnification, and dye concentration is needed.

Field identification & locations

Common sources include India, Brazil, Russia, Australia, and Madagascar, depending on material. Check for dye pooling in cracks, color concentration around drill holes, and reaction to a steel point; avoid destructive tests on jewelry.
