Diamond Colour

The Essential 7C's

For white or colourless diamonds (as opposed to coloured diamonds, which is a whole different story), the diamond industry has adopted an alphabetical colour scale from D to Z, with D as the highest grading. As you go down the scale, the diamond starts to develop a yellow or brown tint.

 

Experts in the world of diamonds determine the colour by comparing a diamond against a master set of diamonds of different colours. Without comparing diamonds side by side, it is very difficult to see the difference between a D and a G.

Completely colourless diamonds (such as D and E) are much rarer than others which is why they come with a higher pricing premium. The key question is always where to draw the line when choosing the colour of a diamond – how far can you compromise colour before the diamond is too tinted? The answer to this question is relative to your budget and quality expectations.

 

Below we focus on the 7 main colours used in Diamond Jewellery.

Colour D

D is the highest colour grade attributed to a diamond, denoting that the stone is completely colourless (white); as such, they are extremely rare and command the highest prices.

Colour E

The colour difference between a D and an E graded stone is usually only visible to an expert gemologist using master stones as a comparison, although E graded stones are slightly cheaper.

Colour F

The colour difference between an E and an F is only visible to an expert gemologist using master stones as a comparison. F grades are the lowest and therefore least expensive of the premium colours.

Colour G

G graded diamonds are nearly colourless and a slight colour difference only become perceptible when compared to diamonds of grades D or E. G stones appear colourless especially once set and therefore offer excellent value for money

Colour H

H coloured diamonds are near colourless diamonds which still appear totally white or colourless if they are not compared side by side with higher colour graded stones. The H colour is generally considered the watershed between colourless diamonds and slightly tinted diamonds.

Colour I

I coloured diamonds are very slightly tinted diamonds, however, once set in jewellery, these stones may appear colourless. If you are looking to maximize your budget, then an I coloured diamond offers great value for money.

Colour J

J coloured diamonds are very slightly tinted diamonds, however, once set in jewellery, especially in yellow gold, it is harder to see the slight yellow tint which the J grade produces.

Colour k

K coloured diamonds are slightly tinted diamonds, however, once set in jewellery, especially in yellow gold, it is harder to see the slight yellow tint which the K grade produces.

Colour L

Luxor Jewellers currently offers stones in the higher range of D-J, as these are the only grades we recommend, however, lower clarity grades can be made available on special request.
