the remains are then purified and graphitized using the halogen purification technique this is done by placing the remains in a high temperature vacuum induction furnace the high temperature vacuum induction furnace utilizes vacuum pressure in the range of 30 torr to 500 torr and a temperature up to 3000 degrees centigrade chlorine gas is injected into the furnace and reacts with the impurities to form chlorides the impurities leave the carbon in the form of chloride gases after the impurities have been removed the carbon that remains can be pure within 10 ppm in addition to being pure within 10 ppm the carbon also becomes graphitized by the high temperatures which is necessary to provide graphite for the crystal growth process in the preferred embodiment the process of crystal growth from sublimation is used according to techniques of the type described but not limited to the process described in u s pat nos 34 061 6 200 917 6 025 289 6 045 613 4 042 673 and 5 762 896 in the preferred embodiment the purified graphitized carbon from human remains is used to replace or supplement purified graphitized carbon of other origin and processed into synthetic diamonds in the preferred embodiment the synthetic diamond may be a gem quality diamond that can be faceted and polished utilizing conventional faceting and polishing techniques which are well known in the art it is further contemplated that the diamond can be a white diamond or a tinted diamond such as a yellow or blue diamond techniques for tinting or coloring diamonds are known in the synthetic diamond production art and involve the introduction of dopants generally in very small proportions or utilization.
