When it comes to choosing the right color for your diamond is based on your preference. It is important to buy a diamond with little to no color for a better shine and quality.

Diamonds are colored when the crystals grow inside of the earth. Tiny flakes of some elements like nitrogen are coloring the diamonds, the pressure involved in the formation of the diamond creates a deformity in the crystal structure, this process determines a diamond coloring. 

The Gemmological 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 - it is considered a colorless stone. The diamond at the higher end of the scale (Z) has deeper tones. However, when a diamond's color is more intense than the "Z" grading, it enters the realm of a "Fancy Color" diamond. In this case, the intensity of the color in the diamond can play a significant role in its value. The value of a Fancy Colored Diamond can surpass that of colorless diamonds if the intensity of the color is high and the color is rare.

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

K, L, and M are faintly 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 1/2 carat or more are colorless. Most of the diamonds sold are graded G to L. For fancy diamonds, the value goes up with the intensity of the color.

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

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

It is important to know if you put a truly colorless diamond in a yellow gold setting will reflect on the stone causing a yellowish tint.

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

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