Color Enhancement is a safe, non-radioactive form of irradiation that transforms a polished, refined white diamond into a permanent, safe and beautifully colored diamond with the brilliance of naturally colored diamonds. The process of color enhancement uses high-energy electron saturation (electron accelerator technology) to alter the appearance and color of diamonds. With this process and varying degrees of irradiation, jewelers are able to transform naturally white diamonds into brilliant stones featuring hues such as canary yellow, pink, blue, gold, green, cognac, orange and black. Different levels of heat combined with various shaped diamonds allow the jeweler to masterfully create beautifully colored works of art. The process of color enhancement is flawless and can only be detected with spectroscopy. The result is a beautiful, permanent, radiation-free colored diamond.
