The less colour in a (white) diamond the more valuable it is.
The diamond industry’s colour scale (for white or colourless diamonds) indicates how much colour is visible in a diamond. The scale runs from D through to Z referring to a yellow tint that increases in intensity as you move down the scale.
Truly colourless, ‘D’ colour diamonds, are the most rare and valuable and therefore come at a premium. When choosing a diamond, you must consider how much of a price premium you are willing to pay to attain as close to a colourless diamond as you desire.


How to compare

Choosing a diamond with a particular colour is a matter of personal taste and should be looked at in combination with the metal colour of the piece of jewellery as well as what the purpose of purchase is.
Most high street jewellers will stock G or H colour diamonds as they provide great value for a near-colourless appearance very close to D. They are suitable for most customers and are often described as commercial grade or commercial quality.
Remember that it is always important to consider colour with the other C’s to find the combination that suits your needs and expectations. Have a look at our diamond comparison tool to get to grips with the price differences between colour gradings.

  • Ideal cut diamonds offer a little flexibility in colour selection. Because Ideal Cut diamonds are designed to maximize brilliance and scintillation they also tend to mask subtle colour differences making H and I colour diamonds appear beautifully white. Ideal Cut H and I colour diamonds tend to appear whiter than poorly cut diamonds of the same colour.
  • H colour diamonds are often popular for being very close to colourless to the naked eye and so offer great value.
  • The best way to assess diamond colour is to view it from the side, un-mounted, against a white background, using a daylight fluorescent bulb.
