Likely polished blue-green stone bead or small gemstone

Uncertain from the photo; possibly dyed or treated agate/chalcedony, but identification requires testing

AI-generated identification · may be incorrect

Small, glossy, opaque-to-translucent blue-green piece with a shaped, tapered form. Hardness, mineral composition, and crystal structure cannot be reliably determined visually; agate/chalcedony, if confirmed, is microcrystalline quartz (Mohs 6.5–7).

AI Estimated Value

About $1–$20 if an ordinary stone bead; higher only if testing confirms valuable natural material or notable workmanship.

Physical properties

Formation & geological history

If agate/chalcedony, it formed as silica-rich fluid filled cavities or fractures and deposited in layers; its geological age depends on the host rock. The polished shape indicates human processing.

Uses & applications

Could be used as a bead, pendant component, or decorative object; its value depends on material, treatment, and craftsmanship.

Geological facts

Blue-green color alone cannot distinguish natural gemstone from dyed stone or imitation material; gemological testing is needed.

Field identification & locations

Look for natural banding, translucency, and consistent hardness, but these clues are inconclusive in a tiny polished piece. Common agate sources include Brazil, Uruguay, India, and Madagascar.
