In graphite the bonds are sp2 orbital hybrids as well as the atoms type in planes, with Each and every sure to a few nearest neighbors a hundred and twenty degrees apart. In diamond they are sp3 along with the atoms sort tetrahedra with Every single bound to 4 closest neighbors.[four][5] Tetrahedra are rigid, the bonds are solid, and of all known substances diamond has the best number of atoms for every unit volume, Which is the reason it truly is each the toughest as well as the least compressible.

It is possible that diamonds can type from coal in subduction zones, but diamonds fashioned in this way are unusual, as well as the carbon source is a lot more likely carbonate rocks and natural carbon in sediments, instead of coal.[69][70]
