Formation of Diamonds

There are three basic forms of diamonds namely Octahedrons, Cubes and Dodecahedrons. Diamonds crystallize either as octahedrons or cubes; this depends on the conditions at which the diamond is formed. Primarily, diamonds form in an octahedral pattern, (hence the primary growth pattern). Then due to a change in conditions where they are formed, this results in a change in the growth pattern. Therefore, Cubic growth is the Secondary growth pattern of diamonds. Because of this factor, cubes have a tendency of inverted or concaved faces and a thick surface layer which makes it very difficult to see inside the diamond. Read more...
