2016-7-25 · The growth chamber is heated to 1300-1600 °C with pressures above 870,000 pounds per square inch. The molten metal dissolves the high purity carbon source. Carbon atoms precipitate on a small diamond seed crystal, and a synthetic diamond begins to grow. The lab-grown crystal is then cut and polished by a diamond cutter.
