How are laboratory-grown diamonds made?

Our laboratory-grown diamonds are made using the Chemical Vapor Deposition (CVD) method. The CVD process begins by filling a vacuum chamber with gasses containing carbon. After that, a thin sliver of diamond seed is placed in the chamber. The chamber is then heated to 800 to 900 C. At these temperatures, the heat begins to break the gasses molecules, and carbon atoms crystalize on the diamond seed, growing it into a diamond - sort of like how snowflakes accumulate in a snowfall!
