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.
