Physical properties

Formation & geological history

Natural diamonds crystallize deep in the mantle under high pressure and temperature, commonly billions of years ago, then reach the surface in volcanic kimberlite or lamproite. The stone has been cut and mounted.

Uses & applications

Jewelry; diamonds are also used in cutting and drilling tools.

Geological facts

A faceted look alone cannot distinguish diamond from simulants such as cubic zirconia or glass; gemological testing is needed.

Field identification & locations

Identify by professional testing of thermal/electrical conductivity, refractive properties, and inclusions; common sources include Botswana, Russia, Canada, and South Africa. The image does not establish the stone or setting materials.
