How are flash created diamonds made?

Labs use two different methods to grow diamonds—High Pressure-High Temperature (HPHT) and Chemical Vapor Deposition (CVD). When the HPHT method is used, a small diamond seed is placed into a piece of carbon. … The newly formed diamond is then carefully cooled.

Are lab created diamonds valuable?

Are Lab-Created Diamonds Worth Anything? Lab-created diamonds are less valuable than natural diamonds.
