Diamond Color

Diamond color is an extremely important topic to understand.

Many times foreign materials interfere with the creation process of a diamond and “paint” the diamonds in different shades, and thus a diamond is not colorless. Some of them are extremely desired like intense red or blue, but others are considered to be less desired or even undesired like brown or yellow tinge.

This post will help you with the white diamonds color grading system. 

The GIA Lab took all the white diamonds and sorted them by how colorless they are. D represents a completely colorless diamond (it is the most expensive diamond), then E, then F, and all the way to Z.

In general those are the main groups:  

D-F – colorless diamonds
G-J – near colorless
K-M – very light color
S-Z – light color

In our experience most people buy diamonds between the D-M color. This is the range we are focusing on.

What can you learn from this diamond color scale:

As you can see, the difference between 2 following colors is quite small. Please keep in mind that we have the best conditions to photograph. So don’t choose a color in advance, only the color range you want to go with. This way you will not be locked on letters but rather on choosing the best looking diamond for you.

If you have a good eye you can see that the yellow tinge is heavier from K color. So we believe that for white gold or platinum you should choose a color between D-J.  On the other hand, yellow gold or even the rose gold color will give the diamond a tinge, so it’s really not necessary to pay for the highest colors. We believe that you should choose a diamond with your own eyes.


Take this common scenario – there could be 2 diamonds –  one is E color and the other one is F color. Otherwise they have the exact same grading marks. In real life, the F is truly lively and more full of life than the E.   If you buy online you might go for the higher letters, and this might prevent you from picking the right diamond for you.
