The D color diamond is the undisputed queen of color. When paired with flawless or internally flawless clarity and a top cut grade there is no higher pedigree in the diamond world.

PriceScope Pointer: A difference of 2-3 color grades is hard to detect unless you hold the diamonds next to each other. The most purchased diamond colors are graded F-G-H or I, set in white gold or platinum.

D Color Described

Diamond color is typically graded on a scale descending from D, which means no hint of color, to Z, which means light yellow or light brown.

A D color diamond is the most “colorless” in the highest range of colorless diamonds, which includes D, E, and F colors. There are no color grades higher than D color, while there are 22 grades lower than a D color diamond.

A grader giving a diamond D color is describing a complete absence of color: Most of the world’s diamonds have some traces of yellow or brown, caused by chemicals in the earth where they formed. Diamonds with stronger levels of yellow and brown, as well as colors other than yellow or brown are categorized as fancy colored diamonds and graded using a different scale.

Let’s Get Practical

D color diamonds are not the most popular choice, primarily because of the expense that rare designation commands. The most purchased diamond colors are graded F-G-H or I, set in white gold or platinum. A difference of 2-3 color grades is hard to detect unless the diamonds are held next to each other and directly compared.

Will a color D diamond show any tint?

No. A D color diamond will be completely colorless. The only exception might be a color D diamond with medium or stronger fluorescence when exposed to ultraviolet light. When excited, any visible tint will be the same color as the fluorescence.  

Three Factors that can Influence Color

Diamond color is analyzed with the stone in the upside-down position, analyzed from the side. This is done because three factors may influence diamond color appearance when seen from the top: The diamond’s shape, the way it was cut, and the presence of fluorescence.

As it relates to D color:

  • A D color diamond will continue to be completely colorless, regardless of shape.
  • A D color diamond will not have any color reduction due to sub-par cut quality. Nevertheless, read our section about diamond cut which unarguably has the most influence on overall beauty.
  • As mentioned above, the presence of fluorescence could cause a D color diamond to have a visible tint.

Real World Information

A D color diamond will not sparkle better than a diamond with lower color. A diamond’s observable brightness, fire, sparkle, and contrast are all attributable to its cut-quality. A diamond’s optical properties are not influenced by its color grade, except for variance in spectral absorption minutia which is rarely relevant.

D Flawless Prestige

A D color, when paired with flawless or internally flawless clarity and a top cut grade (for round brilliants) represents the highest pedigree in the diamond world. This “D Flawless” (or IF) pedigree becomes even more prestigious when the diamond is confirmed to be Type IIa, the most chemically pure in nature.

Collection Quality

A D color, when paired with FL/IF, VVS1, or VVS2 clarity and a top cut grade, is considered to have collection quality. Such diamonds, with the purest natural color and clarity grades, have typically held their value best over time and have special status in the eyes of many diamond professionals, collectors, enthusiasts, and auction houses.

Intermediate D Color Diamonds

Where does a D color diamond rank?

The internationally accepted grading scale and terminology for diamond color in the normal range consists of 23 grading levels. Grading is performed with the diamond upside down. A D color diamond represents the highest, most colorless point on the scale.

Standards, Subjectivity, and Value

While the descriptive scale above is universally applied, standards can vary between individuals and organizations that decide a diamond has D color.


Variance between reputable graders and organizations may be attributable to standard deviation. Color and clarity judgments are matters of opinion and diamonds often sit on the border of two grades. The only time this becomes an issue is when a buyer and seller disagree about which set of grades establish the diamond’s value.

Value and Over Grading

Intentional over grading has been a historic issue in the diamond trade. Over grading is a willingness to purposely deviate from internationally accepted standards to inflate the perceived value of a diamond. Certain locations of the EGL (now closed) became infamous for over-grading loose diamonds, by 3-4 grades in some cases, permitting unscrupulous sellers to overcharge consumers.

Value and Under Grading

Under grading occurs when a jeweler examines a diamond and claims it was over graded to create fear-based doubts in the diamond owner’s mind. The most frequent example of under grading is when one jeweler implies a consumer overpaid a competing jeweler, hoping the consumer will return the diamond and purchase there, instead.
