The UTIAS Implosion Chamber Facility was used to synthetically convert graphite powder in diamonds. Pure graphite powder, enclosed in a graphite cartridge, was placed at the center of the UTIAS Implosion Chamber and it was then subjected to an explosive-driven implosion which compressed the graphite powder to very high pressures and temperatures, thereby producing diamonds. A number of tests including density, hardness, scanning electron microscope, and conclusive X-ray diffraction tests were performed to confirm the presence of diamonds in the shocked graphite powder. It was found that small amounts, 3 to 5 percent of the original graphite powder, was converted to diamonds.
