A transparent carbon plate, known as a seed, is placed inside a low-pressure microwave chemical vapor deposition chamber.

Methane and Hydrogen gases are combined with electrical energy, a plasma ball ignites, carbon molecules form on the seed, and six to 10 weeks later a carat diamond is formed, laser-cut and polished.
