Types Of Colored Diamonds

There are two types of colored diamonds, natural colored diamonds and enhanced. With natural colored gems the color is formed naturally when the stone is created under the earths surface. The color can be produced by different elements like hydrogen, nitrogen or natural radiation that are present when the heat and pressure under the earths surface forms the stone.

Enhanced or treated gems refer to those that are created in a laboratory setting. In some cases the stone already has some color but this color can be enhanced with things like irradiation and heat in a controlled lab setting. This can create a richer more desirable color.
