Because of the popularity of coloured diamonds, treated stones are an alternative to natural gems. High pressure, high temperature treatments can enhance the existing yellow tones of low quality diamonds, creating vivid shades and more desirable, intense colors suitable for yellow diamond engagement rings.

Diamonds may also be irradiated to create an artificial coloration. If a diamond has received any such enhancements, the details of the treatment should be disclosed either on the gem's certificate or by the jeweler.
