Diamond Colour Guide

Diamond colour guide – chart and grades

A diamond colour with the highest grade is the one with the least amount of colour. Diamonds graded as D indicates that it is colourless, and therefore extremely rare and valuable. Diamonds graded as E in colour, show minute traces of colour detected by an expert. An F grade indicates slight traces of colour. A stone-graded G-H range is near-colourless, with traces of yellow generally visible only when compared with whiter diamonds. I to J are also near-colourless, only slightly detectable to the unaided eye. K-M, begin to display noticeable colour.

Your Diamond Colour Guild

Colour differences in diamonds are very subtle. To grade diamonds, you have to have controlled lighting conditions. All are compared against a master set of diamonds for accuracy. The presence of colour in a white diamond diminishes the diamond’s value.

This diamond colour guide is to help you with white diamonds, but you can get coloured diamonds too.

Diamonds come in an array of colours Red, blue, pink, purple and even green. This sort of diamond is known as fancy diamond, extremely rare so commands a higher price.

Engagement Ring Settings

Colour becomes much harder to detect once the diamond is set in a ring and placed in an environment that contains colour (when grading a diamond a white background is used in grading). For instance, a G-coloured diamond may look as colourless as a D when set in a ring under normal lighting conditions, especially if the two are not compared side by side.

Another factor that affects a diamond’s apparent whiteness is the colour of the ring itself. Yellow gold reflects a small amount of yellow into the diamond making it look less white. White gold or platinum setting makes the colour of yellow diamonds stand out more.

What diamond colour grade is the best?

When it comes to diamond colour grading, a colourless diamond is incredibly rare and carries a premium because of this. The higher the colour grade, the less colour there is present in the diamond. The lower the grade, the diamond will likely exhibit a very slight yellow or brown tint.

Similarly to most diamond characteristics, choosing your diamond colour really depends on your personal preference.

If having the highest diamond quality is important to you, we recommend choosing a colour D, E, or F diamond that is in the colourless category. These diamonds are incredibly rare, which is reflected in the premium price point of diamonds in the colourless category.

If you prefer to spread your budget and balance the 4 Cs of diamond quality across other elements, it would mean you could select a colour grade G-J. The colour difference between these grades and the colourless category is minor and not visible to the untrained eye. This would allow you.
