Diamond Color Grade: charts & scale Guide to help to choose the diamonds

Choosing the right color for your diamond is a personal preference. It’s important to remember that you are generally searching for a stone with little to no color.

Diamonds get their color when the crystals grow inside the Earth. Tiny traces of some elements like nitrogen can color the crystals. Also, the pressure involved in the diamond formation creates distortion in the crystal. It is also believed to contribute to their color.

The color evaluation of gem-quality diamonds originates from the absence of color. The Gemological Institute of America (GIA) uses a 12-letter alphabetical scale of D to Z.

Using this scale, the diamond on the lower end of the scale (D) will have the least amount of color. You can consider it a colorless stone. The diamond at the higher end of the scale (Z) has deeper tones. Yet, a diamond’s color can be more intense than the “Z” grading.

Then, it enters the color in the diamond and can play a significant role in its value. The value of a Fancy Colored Diamond can surpass that of colorless diamonds. This is especially valid when the intensity of the color is high and the color is rare.

D grade is completely colorless

E and F are essentially colorless. The difference between D, E, and F is so slight that only experts can see it when they unmount the diamonds.

K, L, and M are less tinted. Diamonds under 1/2 carat appear colorless when mounted. Diamonds over 1/2 Carat may show a tint of color.

Grades N through Z have a light tint, and it is visible.

Diamonds with less color are more rare and valuable. Only about 5,000 of the polished diamonds produced each year weighing of carat 1/2 or more are colorless. Most of the diamonds sold are grades G to L. For fancy diamonds, the value goes up with the intensity of the color.

Fancy colors include bright yellow, pink, champagne, blue and green. Red, purple and orange diamonds, though found in nature, are very rare.

How the diamond is set can make a difference in color too. Color is more important in rings than earrings and pendants. This is because the diamond is usually larger in that jewelry.

Putting a colorless diamond in a yellow gold setting will reflect on the stone. This will make it have a more yellowish tint.

Colorless and near-colorless diamonds come alive in platinum or white gold setting.

A slight yellow-tinted diamond will appear whiter in a yellow gold setting. Keep in mind that color is only one of the Diamond 4Cs. So even when a stone has a visible tint, it can still be very lovely when mixed with good clarity and cut.
