What is the GIA Diamond Color Chart? | Rare Carat

GIA Diamond Color Chart

The diamond color chart is a way for diamond graders to communicate to you the amount of color found in a particular diamond. It’s also a way for you to determine which diamond out is of a higher quality, especially if you don’t have the stone in front of you. The chart looks like this:

Rare Carat Diamond Color Guide showing Colorless (D, E, F) Near-Colorless (G, H, I, J) and Very Faint Yellow (K, L, M) color range

Perfectly colorless diamonds fall in the D-F bracket or range, near colorless in G-J, and so on down the line.

Because diamonds are mostly valued for their lack of color, the closer the diamond sits to ‘colorless’ on this scale, the pricier. If you want a great diamond but don’t like the idea of your kids still living at home at the age of 45 because you blew all their college money on diamonds, you need to visit our page on diamond color immediately and find out all you can about it.
