How Diamonds Grow

Step 1

Place diamond seeds on pedestal. Depressurize chambers to one-tenth of an atmosphere.

Step 4

Let it grow. Wafer seeds gradually become diamond crystals, building up at half a millimeter a day.

Step 2

Inject hydrogen and natural gas (CH4) into chamber. Heat with microwave beams at 1800 degrees Fahrenheit, electrons from nuclei, forming plasma.

Step 5

Open chamber and remove diamond crystals.

Step 3

Let it rain. Freed carbon precipitates out of plasma cloud and is deposited on wafer seeds.

Step 6

Slice and shape for industrial applications or cut and polish into gems for jewelry.
