Parisian diamond. An old misnomer for a diamond imitation. Parsons, Hon. Sir Charles Algernon (1854-1931). An English engineer m\<\ inventor who, in 1918, attempted lo produce synthetic Diamonds by re peating the experiments of Moissan and Crookes with variations, and was convinced that these methods could not be successful. In one novel experiment he fired a blank shotgun shell against the piston of a compres sion chamber that was filled wilh carbon. When this was unsuccessful he sought still higher pressures by discharging bullets into a tapered carbon-filled hole in a steel block. Pressures of 5000 tons per square inch were supposedly obtained in this manner. There is no proof that his experiments were successful, See
