Faceted transparent gemstone pendant

Likely cubic zirconia (zirconium dioxide, ZrO₂); possibly diamond or synthetic moissanite

AI-generated identification · may be incorrect

A colorless, brilliant-cut stone in a metal setting; apparent high luster and strong facet reflections. Exact hardness, crystal structure, and specific gravity cannot be confirmed from the photograph; cubic zirconia is Mohs 8–8.5, diamond 10, and moissanite 9.25.

Category: gemstone
Identified: September 7, 2026
Method: Standard

AI Estimated Value

About $10–$75 if cubic zirconia in plated metal; roughly $50–$300 if moissanite; hundreds to thousands of dollars if a genuine diamond, depending on carat, color, clarity, cut, and metal.

Physical properties

Formation & geological history

The pictured stone is likely laboratory-grown rather than naturally formed; cubic zirconia crystallizes synthetically from molten zirconium oxide. Natural diamond formed deep in Earth’s mantle over roughly 1–3 billion years, but this image cannot establish identity or age.

Uses & applications

Used in jewelry as a diamond simulant or gemstone. The chain and setting appear manufactured metal, possibly gold-colored alloy; the pendant itself has jewelry value mainly determined by stone identity and metal purity.

Geological facts

The starburst appearance is produced by faceting and reflected light, not necessarily natural inclusions. Refractive-index, thermal-conductivity, loupe, and gemological testing are needed for identification.

Field identification & locations

Field identification is not reliable; inspect for facet quality, inclusions, wear, hallmarking, and test the stone professionally. Common synthetic examples are widely produced worldwide.
