    How Are Lab Grown Diamonds Made? : The Remarkable

    In the CVD process, a thin slice of diamond seed (often an HPHT produced diamond) is placed in a sealed chamber and heated to around 800 degrees Celsius. The chamber is then filled with a carbon rich gas (usually methane) along with other gases. Then, the gases are ionized into plasma using microwaves, lasers, or other techniques.

    Trace amounts of nitrogen in a diamond will produce a yellow color. Keeping it out of the diamond growing process was impossible at that time. In 1989 the first diamonds were grown by the CVD (chemical vapor deposition) process. This process is better suited to growing gem-quality diamonds because fewer impurities are introduced into the diamond.

    Chemical vapor deposition (CVD) is a vacuum deposition method used to produce high quality, high-performance, solid materials. The process is often used in the semiconductor industry to produce thin films.. In typical CVD, the wafer (substrate) is exposed to one or more volatile precursors, which react and/or decompose on the substrate surface to produce the desired deposit.
