Rosendorff Authenticity Colour Grading

When choosing a pink diamond there are three important factors to consider; hue, tone and saturation. 

Hue is the dominant colour of the diamond; tone is the amount of light or darkness in the diamond; and saturation is the strength of hue. The more intense the colour, the rarer and more valuable the diamond.

While clarity and carat weight ordinarily impact on the value of white diamonds, these characteristics are less of a consideration in the value determination of Argyle pink diamonds, with the focus instead being on colour and cut.
