Colour grading

There are three important factors to understanding the colour of pink diamonds: hue, tone and saturation.

Hue

The dominant colour of the diamond

Tone

The amount of light or darkness in the diamond

Saturation

The strength of hue

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.
