Physical properties

Hardness 10 on the Mohs scale, transparent to opaque, adamantine luster, isometric crystal system with perfect octahedral cleavage, specific gravity of 3.52.

Formation & geological history

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

Uses & applications

Widely used in high-end jewelry as a gemstone and extensively in industrial cutting, grinding, and drilling tools due to its extreme hardness.

Geological facts

Diamond is the hardest known natural material on Earth and conducts heat much faster than copper.

Field identification & locations

Identified by its supreme hardness, high refractive index, and adamantine luster; found in countries like Russia, Botswana, Canada, and South Africa.
