Physical properties

Formation & geological history

Natural diamonds crystallize deep in Earth’s mantle under high pressure and temperature, commonly billions of years ago, and reach the surface in volcanic kimberlite or lamproite. The ring is a human-crafted setting.

Uses & applications

Jewelry and adornment; diamonds are also used in cutting and abrasive tools.

Geological facts

A photograph cannot reliably distinguish diamond from cubic zirconia, moissanite, or other clear stones, especially at this size.

Field identification & locations

Confirm with a jeweler using gemological tests and inspect markings for metal fineness; do not rely on sparkle alone. The setting appears to contain a row of small stones, but the image does not show enough detail to identify them conclusively.
