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 gases containing carbon. A thin sliver of diamond seed is placed in the chamber, which is then heated up to 900° C. At these temperatures, the heat begins to break down the gas molecules and carbon atoms crystalize on the diamond seed, growing it into a diamond—similar to how snowflakes accumulate during snowfall!
