How to choose a Diamond? Check out this colour guide to make sure you select the right diamond for you.

DIAMOND COLOUR GRADING, HOW DOES IT WORK?

White diamond colour grading is scored on a scale of D through to Z. Diamonds with a colour grading of D are deemed more valuable than a diamond with a score of Z.

A diamond of D grade has no tints of yellow colour in it. This means it’s seen as the purest colour a diamond can be.

As for a diamond with the colour grade of Z you will noticeably see the difference as the diamond will be heavily tinted yellow.

Many professional jewelers will not sell a white diamond below the colour grade of I. Once you see a white diamond at a grade of H through to Z, you can start to see a noticeable difference in the final diamond colour.

So if you have a prized diamond ring in mind, be careful to check for its colour grade. Expect to pay less for a diamond that is graded below the grading of D.

WHO GRADES THE DIAMONDS?

The GIA grades most white diamonds and they provide a certificate to show the grade awarded to the diamond you might be thinking about buying. The diamonds are accurately measured using equipment contained in a special environment. This allows for the detection of slight changes in each diamond. The diamond industry uses the GIA diamond colour scale for most of diamonds bought today.

DIAMONDS COLOUR CHART?

Have a look below at this handy chart to show how each diamond is scored. You will see a slight colour change in each diamond. However, even when we applied a slight change to the images, the changes are almost not noticeable. The same is for real diamonds. It’s hard to detect a miner colour fluctuation with the naked eye.

D Exceptional White +

A diamond with a grade of D is the very rarest of the diamond colour ranges. The diamond will be completely colourless. This makes it the most valuable coloured diamond.

Grade: Colourless           

E Exceptional White

A diamond with a grade E is also very rare. The difference between D and E is hard to detect when compared. This diamond is graded colourless. This also makes it very valuable.

Grade: Colourless           

F Rare White +

The third highest coloured graded diamond achievable. It’s graded F as the diamond is colourless when viewed through the crown.

Grade: Colourless when viewed through the crown      

G Rare White

A fine alternative to the top three colour grades. This colour still makes for an outstanding diamond. Its grade of G is colourless when viewed through the crown.

Grade: Colourless when viewed through the crown      

Grade G – J are nearly colourless, with distinctions so subtle most are indistinguishable to the untrained eye. Diamonds in the near colourless scale won’t exhibit a noticeable tint in most cases.

The colour grade system goes all the way to Z, however we recommend a colour grade J and above.
