How a Diamond is Formed. In order for diamond to form there must be an available source of carbon and relatively narrow ranges of temperates and pressures must align. This happens around 100 miles below the crust. Once crystalized the diamonds must be rapidly transported to the surface without undergoing substantial change.
Note that the diamond is made of the element carbon. To be a diamond the carbon atoms have to be in a special order or stacking relative to each other. When you melt the diamond the carbon atoms are no longer in this special order and when it cools back down they do not return to the original stacking.
