2024 Diamond Color Chart Buying Guide

GIA Diamond Color Chart

The GIA (Gemological Institute of America) Diamond Color Chart is a widely recognized and standardized system for evaluating the color of diamonds. The color of a diamond is an essential factor in determining its value, as it directly impacts the overall appearance and desirability of the stone. The GIA Diamond Color Chart is designed to provide a consistent and objective method for grading diamond color.

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 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.

  • D-F: Colorless: These diamonds are extremely rare and valuable, with no discernible color when viewed by an expert under controlled lighting conditions.

  • G-J: Near Colorless: These diamonds have very subtle traces of color that are difficult to detect, even for an expert. They appear colorless to the naked eye and are often popular due to their value and appearance.

  • K-M: Faint: Diamonds in this category have a slight yellow or brown tint, which becomes more noticeable as the diamond grade moves toward M. These diamonds are still considered desirable. However, they may not command the same premium as colorless or near-colorless stones.

  • N-R: Very Light: The color in these diamonds is more apparent, with a noticeable yellow or brown hue. These diamonds are typically more affordable and may appeal to those seeking a warm-toned stone.

  • S-Z: Light: Diamonds in this category have a distinct yellow or brown color that is easily visible to the naked eye. They are the least valuable in color but may still be appreciated for their unique appearance.

It's important to note that the GIA Diamond Color Chart only applies to white diamonds. Colored diamonds, also known as "fancy color diamonds," are graded using a separate system that evaluates their color intensity, hue, and saturation.

Because diamonds are mostly valued for their lack of color, the closer the diamond sits to ‘colorless’ on this scale, the pricier. Suppose 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. In that case, you need to visit our page on diamond color immediately and find out all you can about it.
