Diamonds range in color from icy winter whites to warm summer whites. Diamonds are graded on a color scale established by the Gemological Institute of America (GIA) which ranges from D (colorless) to Z.

Warmer colored diamonds (K-Z) are particularly desirable when set in yellow gold. Icy winter whites (D-J) look stunning when set in white gold or platinum.

Color differences are very subtle and it is very difficult to see the difference between, say, an E and an F. Therefore, colors are graded under controlled lighting conditions and are compared to a master set for accuracy.

Truly colorless stones, graded D, E, and F are treasured for their rarity, are highest on the Diamond Quality Pyramid. Color, however, ultimately comes down to personal taste. Engagement ring color selection should generally stay in the range of D through J.

D-F Colorless	G-J Near Colorless	K-M Slightly Tinted	N-R Very Light Yellow	S-Z Light Yellow - Yellow

Color: D
A diamond of this color grade is highly prized, as a diamond with less color has never been found. This grade of diamond is absolutely colorless.

Color: E
An E-color diamond is colorless and also highly prized. Only a trained gemologist using special equipment can determine any color difference between a D- and an E-color diamond.

Color: F
No color is visible to an untrained eye in an F-color diamond. As the least expensive diamond color in the colorless range, F-color diamonds display minimal color difference from D- or E-color diamonds and offer a lower price. This is the best value for a colorless diamond.

Color: G
This diamond is nearly colorless. A diamond with G-color has an extremely faint tint that is only noticeable to a trained gemologist. G-color diamonds offer great values and make for beautiful jewelry, since they are less expensive than the colorless grades, but appear to the eye to be colorless when mounted.

Color: H
This diamond offers an exceptional balance of color and cost in the near-colorless range. If you choose an H-color grade diamond, you can buy a larger diamond for same the price as a higher color grade. The very slight tint is generally not noticeable.

Color: I
This diamond, when cut to ideal proportions, produces a warm brilliancy not found in the higher grade colors. I-color diamonds are less expensive than other diamonds, so you can buy a larger diamond for the same price as a higher color grade. Note: If this diamond has medium or strong blue fluorescence, its slight tint will be partially masked, making the diamond appear whiter to the eye. with a negligible visible difference from an ideal-cut diamond, but at a lower price.

Color: J
This diamond, when cut to ideal proportions, produces a warm brilliancy not found in the higher grade colors. As the least expensive diamonds in the near-colorless range, J-color diamonds present the best value in diamond color, so you can buy a larger diamond for for the price. Note: If this diamond has medium or strong blue fluorescence, its slight tint will be partially masked, making the diamond appear whiter to the eye.
