Are colored diamonds radiated or irradiated?
No, for a naturally coloured diamond, and yes, for a treated diamond with enhanced colour. Any diamond can be treated, either chemically or by radiation, to enhance its natural colour. Many naturally coloured diamonds require no treatment, because their colour is judged to be naturally ideal. A certified gemologist can identify a naturally coloured diamond, and can also identify and describe treatments to a diamond intended to enhance its natural colour.
