Natural fancy colour diamonds owe their vibrant, colourful tones and hues to structural imperfections and/or chemical impurities present within their crystalline structures, while perfectly colourless diamonds exhibit very little or no chemical impurities or structural flaws. The amount and the location of said imperfections or impurities will directly influence the intensity, as well as the hue, of any given fancy colour diamond. An increase in nitrogen atoms, for example, may imbue a diamond with a yellow or brown tint, while pink or red tinges arise in diamonds with plastic deformations.
Fancy colour diamonds come in a rainbow of colours and hues, from the more common fancy yellow diamond to the incredibly rare fancy red diamond.
