Colorless faceted gemstone, likely cubic zirconia

Cubic zirconia (synthetic zirconium dioxide, ZrO₂); possibly colorless quartz or laboratory diamond

AI-generated identification · may be incorrect

Round brilliant cut, colorless, transparent, vitreous-to-adamantine luster, strong facet reflections, no visible inclusions. Cubic zirconia has Mohs hardness about 8–8.5 and cubic crystal structure; image alone cannot distinguish it reliably from diamond or quartz.

Common name: Colorless faceted gemstone, likely cubic zirconia
Scientific name: Cubic zirconia (synthetic zirconium dioxide, ZrO₂); possibly colorless quartz or laboratory diamond
Category: gemstone
Identified: August 8, 2026
Method: Standard

AI Estimated Value

$1–$20 if cubic zirconia; approximately $5–$50 if ordinary glass or quartz; substantially more only if confirmed as diamond or another valuable natural gem.

Physical properties

Formation & geological history

Most likely a human-cut synthetic gemstone rather than a natural rock. Cubic zirconia is manufactured by melting zirconium oxide and stabilizers; natural zirconia is extremely rare. The specimen’s geological age is therefore not applicable.

Uses & applications

Used in inexpensive jewelry and ornaments as a diamond simulant. Approximate loose value: $1–$20 for common cubic zirconia; $20–$200+ if it proves to be a natural gemstone or laboratory diamond, depending on size and quality.

Geological facts

The intense rainbow-like flashes and relatively large, broad facets are typical of cubic zirconia, though lighting can exaggerate dispersion. A thermal diamond tester and refractive-index or specific-gravity test are needed for confirmation.

Field identification & locations

The reported Chilean location does not meaningfully identify a cut stone; it could have been manufactured or transported anywhere. Test hardness only cautiously, inspect for facet wear, and use a jeweler’s loupe, refractometer, and specific-gravity measurement for identification.
