How are Diamonds Graded?

Usually when diamond officials talk about color, they are not referring to blues, greens, or pinks. (Such diamonds do exist, but they are referred to as collectively as “fancy” diamonds.) Rather, diamond “color” is used to refer to how pure the shading of a diamond is. The color of a diamond is typically graded on the following scale:

D-F Colorless - Diamonds graded letters D to F are considered to be colorless diamonds. This is the purest color grade, and diamonds of this type are very rare. It is recommended that these diamonds only are set in platinum or white gold in order to enhance the diamond’s spectacular colorless effect.

G-H Near Colorless - Diamonds graded G to J are categorized as near colorless while still containing traces of color. These diamonds are best in a white gold or platinum setting.

I-J Slightly Tinted/Near Colorless - These diamonds are more common and are a good value.

K-M Faint Yellow - Diamonds graded K to M are considered to be faint, and may be visibly less clear than higher grade diamonds. K diamonds have a yellowish hue to them that is easily seen by the naked eye. They are best set in yellow gold, and are a great value. A K diamond is usually half the price of a diamond with a G rating.

N-R Very Light Yellow - Diamonds classified N to R are very light, and may have a very faint yellow or brown color to them. These diamonds are much pricier than diamonds of higher grades.

S-Z Light Yellow - Diamonds grades S to Z are the most colored diamonds. They tend to be an obvious yellow color, and they usually have too much color to be considered a white diamond.

Fancy/ Yellow - Diamonds that are graded as Fancy have deep, vibrant colors that are a result of common impurities in the molecular structure.
