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.
Diamond Clarity. The formation of a diamond is not a gentle process. Most diamonds are born in extreme circumstances from primeval carbon deep in the earthâs mantle at about 500,000 to 2 million feet below the surface. They are then shot up to the surface at supersonic speeds by eruptions inside the earth.
