The two most commonly encountered allotropes of pure carbon are diamond and graphite. In graphite, the bonds are sp2 orbital hybrids plus the atoms type in planes, with Every single bound to a few nearest neighbors, 120 degrees apart. In diamond, These are sp3 and also the atoms form tetrahedra, with Every single sure to 4 nearest neighbors.[four][5] Tetrahedra are rigid, the bonds are strong, and, of all identified substances, diamond has the best number of atoms for every unit quantity, Which is the reason it is actually the two the toughest and also the least compressible.

This can be aided by isotopic courting and modeling of the geological historical past. Then surveyors must Visit the spot and acquire samples, looking for kimberlite fragments or indicator minerals. The latter have compositions that mirror the situations where diamonds form, for example extreme soften depletion or substantial pressures in eclogites. On the other hand, indicator minerals may be deceptive; a much better method is geothermobarometry, where the compositions of minerals are analyzed as whenever they were being in equilibrium with mantle minerals.[sixty six]
At home temperature, diamonds will not react with any chemical reagents such as potent acids and bases.
As with every material, the macroscopic geometry of the diamond contributes to its resistance to breakage.
