Understanding Diamond Colours

The colour grade used to grade diamonds is to establish the presence of a yellow tinge within the diamond. There are categories ranging from Colourless right down to Light. A colourless diamond is obviously pure white with no trace of yellow at all, indicated by the letters D, E, and F.

As with the clarity chart, there is a sliding scale down through the categories until a quite distinctive yellow colour is detected. We stock colourless and near colourless diamonds as standard (D to J), although we can source any colour you like. Diamonds in the colourless category are the most desirable and therefore the most expensive. Usually a diamond of a G colour (top of the near colourless category) is a good bet as it won’t draw much yellow colour at all, but won’t carry the price of the F colour above it.
