Physical properties
Hardness of 10 on the Mohs scale, adamantine luster, isometric/octahedral crystal system, high refractive index, and specific gravity around 3.52.
Formation & geological history
Formed in Earth's mantle under extreme pressure and high temperatures, brought to the surface via deep-source volcanic kimberlite or lamproite pipes.
Uses & applications
Extensively used in high-end jewelry as faceted gemstones, and industrially for cutting, grinding, and drilling abrasives.
Geological facts
Diamond is the hardest naturally occurring substance known. It is composed of pure elemental carbon arranged in a rigid cubic lattice.
Field identification & locations
Identified by superior hardness, thermal conductivity, high dispersion (fire), and adamantine luster using gemological instruments.
