Physical properties
Hardness of 10 on the Mohs scale, adamantine luster, isometric/cubic crystal system, octahedral cleavage, and specific gravity around 3.52.
Formation & geological history
Formed in Earth's mantle under extreme pressure and temperature, brought to the surface via volcanic eruptions through kimberlite and lamproite pipes.
Uses & applications
Predominantly faceted for high-end jewelry; industrial varieties are widely used in cutting, grinding, and drilling tools.
Geological facts
Diamond is the hardest known natural material and is composed entirely of pure carbon organized in a face-centered cubic lattice.
Field identification & locations
Identified by exceptional hardness, thermal conductivity, and intense dispersion (fire); commercially mined in Russia, Botswana, Canada, and Australia.
