Faceted colorless gemstone, likely cubic zirconia or diamond

Cubic zirconia (zirconium dioxide, ZrO₂) or diamond (carbon, C)

AI-generated identification · may be incorrect

Small round brilliant-cut, colorless, highly reflective stone in a metal setting. Diamond has Mohs hardness 10 and adamantine luster; cubic zirconia has hardness about 8–8.5 and similar appearance. The photograph cannot reliably distinguish them or determine clarity, weight, or setting metal.

Common name: Faceted colorless gemstone, likely cubic zirconia or diamond
Scientific name: Cubic zirconia (zirconium dioxide, ZrO₂) or diamond (carbon, C)
Category: gemstone
Identified: September 4, 2026
Method: Standard

AI Estimated Value

About $1–$50 if cubic zirconia; roughly $50–$500+ for a tiny natural diamond depending on carat, color, clarity, cut, and certification; mounted jewelry may be worth more.

Physical properties

Formation & geological history

If diamond, it formed deep in Earth’s mantle under extreme pressure, commonly millions to billions of years ago, then was mined and cut. Cubic zirconia is laboratory-grown and has no geological age; the pictured cut specimen is human-processed.

Uses & applications

Used in jewelry as a central stone or accent. Diamonds have industrial cutting and abrasives applications; cubic zirconia is an inexpensive diamond simulant.

Geological facts

A loupe, refractive-index measurement, thermal/electrical conductivity tester, and professional gem testing are needed for identification; fog tests and scratch tests are unreliable and may damage the setting.

Field identification & locations

The round brilliant faceting and bright sparkle support a faceted gemstone, not a natural rock identifiable by locality. At 33.7°N, 73.1°E, the regional prior does not materially identify a cut stone.
