Yes, CVD Diamonds and Man Made Diamonds are Real

Lab made diamonds, lab grown diamonds, synthetic diamonds, man made diamonds, CVD diamonds, and HPHT diamonds: all terms used interchangeably and sometimes incorrectly to describe pure crystalized carbon created in a lab instead of in the Earth. No wonder so many well-meaning consumers are confused.

Chemical vapor deposition - Wikipedia

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.

Another useful property of synthetic diamond for electronics is high carrier mobility, which reaches 4500 cm 2 /(V·s) for electrons in single-crystal CVD diamond. High mobility is favourable for high-frequency operation and field-effect transistors made from diamond have already demonstrated promising high-frequency performance above 50 GHz.

Look for evidence that it’s a natural Type II diamond, a CVD synthetic, an HPHT-treated diamond, or a CVD diamond that also has been HPHT enhanced. 3. Check fluorescence using a modified technique. If the stone is a Type II diamond, examine the stone with an ultraviolet lamp that provides long-wave and shortwave emission.

Chemical vapor deposition, CVD is the most recent method used for commercial production of synthetic diamonds.In the CVD process methane gas CH₄ is dissociated at low temperature and pressure. The carbon atoms are then deposited on a substrate. This is done four steps: • 1. Pressure in the growth chamber is reduced to almost 1/10th of atmospheric pressure.
