Place diamond seeds on pedestal. Depressurize chambers to one-tenth of an atmosphere.
Let it grow. Wafer seeds gradually become diamond crystals, building up at half a millimeter a day.
Inject hydrogen and natural gas (CH4) into chamber. Heat with microwave beams at 1800 degrees Fahrenheit, electrons from nuclei, forming plasma.
Open chamber and remove diamond crystals.
Let it rain. Freed carbon precipitates out of plasma cloud and is deposited on wafer seeds.
Slice and shape for industrial applications or cut and polish into gems for jewelry.
