Orange Diamond
Ranging from pale translucent saffron to fiery autumnal hues, natural fancy orange diamonds are predominantly found in South Africa. Their colour is caused by the presence of nitrogen. Pure orange, with no hint of brown, is one of the rarest colours and is most likely the result of a combination of nitrogen atoms and structural deformities.
Please note that a significant amount of treated diamonds exist on the market. The purpose of the treatment is to increase the colour.
