This process is used for producing diamonds that are yellowish in color.

CVD Diamond

Cold Vapor Decolorization is a process that is used to turn black diamonds into pale shades of grey. It is also called CVD treatment. The diamonds are cast in a mold and then artificially aged. During this process, a vacuum is drawn on the diamonds. As a result, the diamonds are aged and oxidized without the need of heat treatment. The vacuum is then released. This process is efficient because it doesn’t require heat. It removes inclusions, surface imperfections, and color in black diamonds. It’s reliable for grey diamonds.
