Physical properties
Mohs hardness of 10, adamantine luster, isometric crystal system, perfect octahedral cleavage, specific gravity of 3.51.
Formation & geological history
Formed under extreme high pressure and temperature conditions in Earth's mantle, typically at depths of 140-190 kilometers, and brought to the surface via kimberlite or lamproite volcanic pipes.
Uses & applications
Extensively used in high-end jewelry, industrial cutting tools, abrasives, and precision drills.
Geological facts
Diamond is the hardest naturally occurring substance on Earth and forms under carbon-rich conditions primarily over 1 to 3 billion years ago.
Field identification & locations
Identified by its extreme hardness, high refractive index, and adamantine luster; found in countries like Russia, Botswana, Canada, and South Africa.
