Colorless faceted gemstone, likely cubic zirconia

Cubic zirconia (zirconium dioxide, ZrO₂); visual confirmation is unavailable

AI-generated identification · may be incorrect

Brilliant-cut, colorless, transparent stone with strong facet reflections and very high luster. Cubic zirconia has Mohs hardness ~8–8.5, cubic crystal structure, no cleavage, and specific gravity ~5.6–6.0; diamond is a possible but less likely alternative.

Physical properties

Formation & geological history

Cubic zirconia is synthetic, crystallized from molten zirconium oxide and stabilized with yttrium or calcium; it is not a natural rock. Diamond forms naturally deep in Earth’s mantle, generally over geological timescales, and has Mohs hardness 10.

Uses & applications

Commonly used as an inexpensive diamond simulant in jewelry; typical loose-stone value is about $5–$50, depending on size and cut. A genuine diamond of similar appearance could range from hundreds to many thousands of dollars.

Geological facts

The visible stone is clearly a cut gemstone rather than a raw geological specimen. Facet pattern, sparkle, and photograph lighting alone cannot reliably distinguish cubic zirconia, diamond, moissanite, or glass.

Field identification & locations

The Chilean location does not identify the stone because it is likely manufactured jewelry material. Test with a loupe, refractive-index measurement, thermal/electrical tester, and specific gravity; do not rely on a scratch test. If it is natural diamond, professional gemological certification is required.
