Physical properties

Formation & geological history

A natural diamond forms under high pressure deep in Earth’s mantle, commonly billions of years ago, and reaches the surface in volcanic kimberlite or lamproite. The ring itself is a human-made jewelry setting.

Uses & applications

Primarily worn as jewelry and valued for its appearance; diamonds are also used in cutting and abrasives. Gold is valued for jewelry and corrosion resistance.

Geological facts

The image shows a mounted, faceted stone rather than a geological specimen in its natural setting.

Field identification & locations

Check for diamond identity and gold purity with a jeweler or gemologist; visual inspection alone is inconclusive. Diamonds occur in deposits including Botswana, Russia, Canada, Australia, and South Africa.
