Physical properties

Formation & geological history

If diamond, it formed deep in Earth’s mantle under high pressure and temperature, commonly billions of years ago, and was later brought near the surface by volcanic kimberlite or lamproite. The ring itself is manufactured jewelry.

Uses & applications

Jewelry and personal adornment; gold and diamonds are also valued for investment and collecting.

Geological facts

A clear faceted stone may also be another gemstone or simulant; gemological testing is needed to distinguish them reliably.

Field identification & locations

The image shows a geological gemstone mounted in a ring, but does not establish its identity, quality, or whether the setting is solid gold. Field-style visual clues are inadequate; consult a jeweler or gemologist for testing.
