[00:00:00]But instead of crashing carbon, CVD grows it. A diamond seeds seeds inside of the vacuum chamber. The chamber gets filled with a carbon rich gas, usually methane or hydrogen, and then heated until that gas turns into the plasma.

[00:00:15]Carbon atoms rain down into the seeds layer layer by layer until you have to finish rough diamond. No giant press, smaller machines, lower energy cost, and you can grow much larger colorless stones than HPHT can produce economically.
