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.
Diamonds are better understood. As mentioned before, diamonds actually crystallize in the magma below the crust. However, the magma formations they are found in have a different chemical composition. It is believed to come from greater depths, 110 to 150 miles below the surface. At this depth, the temperatures are higher and the magma is very fluid.
