Physical properties
The image shows small, colorless faceted stones in metal settings. Diamond has Mohs hardness 10, adamantine luster, and a cubic crystal structure; exact identity and any simulants cannot be confirmed from this image alone.
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. These appear to be cut and mounted jewelry stones.
Uses & applications
Used in jewelry and, industrially, in cutting and abrasive tools.
Geological facts
The stones may be natural diamond, lab-grown diamond, or a simulant such as cubic zirconia; visual inspection alone cannot distinguish them reliably.
Field identification & locations
Faceting and brilliance are consistent with diamond-style jewelry, but confirm with a gemologist or appropriate tester. Diamonds are mined in several regions, including southern Africa, Russia, Canada, and Australia.
