Physical properties

Hardness of 10 on the Mohs scale, adamantine luster, isometric crystal system, perfect octahedral cleavage, and a specific gravity of 3.51-3.52.

Formation & geological history

Formed deep within the Earth's mantle under extreme pressure and temperature conditions, then transported to the surface via kimberlite or lamproite volcanic pipes over billions of years.

Uses & applications

Extensively used in high-end jewelry, industrial cutting tools, abrasives, and precision drill bits due to its unmatched hardness and brilliance.

Geological facts

Diamonds are the hardest known natural substance on Earth and can conduct heat five times faster than copper.

Field identification & locations

Identified by extreme hardness that scratches all other minerals, high thermal conductivity, and strong dispersion of light. Found in major deposits globally including South Africa, Russia, Botswana, and Australia.
