Diamond is the cubic modification of carbon and, as a naturally occurring solid, a mineral from the mineral class of elements. Diamonds usually form octahedral crystals, often with curved and striated surfaces. Other observed forms include tetrahedra, dodecahedra, and cubes. The crystals are transparent, colorless, or colored by impurities (e.g., nitrogen or boron) or crystal lattice defects in green, yellow, brown, and less commonly orange, blue, pink, red, or gray to black.

Diamond is the hardest natural substance. On the Mohs scale, it has a hardness of 10. Its grinding hardness according to Rosiwal (also absolute hardness) is 140 times greater than that of corundum. However, the hardness of the diamond varies in different crystal directions (anisotropy). This makes it possible to grind diamond with diamond. The diamond powder used for this contains crystals in every orientation (statistical isotropy), so the hardest among them always act on the object being ground.

Diamond is optically isotropic with high light refraction and high dispersion. It exhibits fluorescence and phosphorescence and is triboelectric. It has the highest thermal conductivity of all known minerals.
