Physical properties

Formation & geological history

Natural diamonds form deep in Earth’s mantle under high pressure and temperature, then reach the surface in volcanic kimberlite or lamproite; their ages commonly range from hundreds of millions to over 3 billion years.

Uses & applications

Used in jewelry and, because of their hardness, in industrial cutting and abrasive tools.

Geological facts

A visual image cannot establish gemstone identity, metal type, or whether the stones are natural, laboratory-grown, or imitation.

Field identification & locations

Check for professional gemological testing; common sources include Botswana, Russia, Canada, South Africa, and Australia. Value depends strongly on stone identity, size, quality, and metal, which cannot be determined here.
