Synthetic diamond crystals were used as opposed anvils whose small culet surfaces were driven into contact with each other to generate high static pressures. Pressures in excess of 68 gigapascals (680 kilobars) were achieved, as determined from the fluorescence line of a ruby fragment sandwiched between the diamonds.
