Process Steps

• 1

  Diamond seed is placed in a specifically designed press.

• 2

  The growth chamber is heated to 1300-1600 °C with pressures above 870,000 pounds per square inch.

• 3

  The molten metal dissolves the high purity carbon source.

• 4

  Carbon atoms precipitate on a small diamond seed crystal, and a synthetic diamond begins to grow.

• 5

  The lab-grown crystal is then cut and polished by a diamond cutter.
