How They Grow
Inspect diamond seeds carefully to ensure they are free of inclusions.
Prepare the surface for growth and place diamond seeds on growth platform.
Control chamber pressure and temperature.
Inject ultra-pure carbon-rich gases and other gases into the chamber.
Excite the gases to an energy level where they form a plasma.
Let it rain. High-energy carbon precipitates out of a plasma cloud and is deposited on the seeds. The atoms are of sufficient energy that they form the diamond allotrope, rather than the lower energy graphite allotrope.
Let it grow. Wafer seeds gradually become diamond crystals, building up at a consistent rate until they reach the desired thickness.
Open chamber and remove diamond crystals.
