CVD Chemical Vapor Deposition. Chemical Vapor Deposition can be described as growing diamonds from carbon-containing gas. CVD process starts from the following: we put a diamond plate inside the vacuum chamber and heat this plate up to 800 ⁰C.Then the chamber is filled with carbon-rich gas (usually methane) which is also heated up to 3000 ⁰C with a microwave beam.

This article reviews the main mistakes to avoid when buying a lab-created diamond: CVD – Avoid brown color hue. Avoid diamonds with strain lines that cause them to look fuzzy. HPHT – Avoid blue color hue ("blue nuance" or "faint blue"). There's a lot of variation in quality between CVD and HPHT diamond manufacturers.
