Physical properties

Faceted, colorless stones with strong sparkle; hardness is 10 Mohs for diamond and about 8–8.5 for cubic zirconia. Metal settings and photographic appearance do not establish stone identity.

Formation & geological history

If diamond, it formed deep in Earth’s mantle under high pressure and temperature, commonly billions of years ago; cubic zirconia is synthetic and manufactured. Geological age cannot be determined from the image.

Uses & applications

Jewelry; diamonds are also used in cutting and abrasive applications.

Geological facts

A gem’s identity cannot be confirmed visually from this photograph; gemological testing is needed.

Field identification & locations

The image shows mounted faceted stones, not enough detail to identify their material or geological source. Check a grading report or have a jeweler test them.
