D color diamonds are undeniably gorgeous. With their stunning icy white color, they’re particularly impressive when the diamond is well cut – this allows a true showcase of its brilliance, beauty and fire. However, even with all this virtue, D color diamonds are not valuable because of their beauty, although it helps, but because they are particularly rare.

They are also often perceived as the “perfect” color for an engagement ring and account for only a small percentage of all diamonds sold worldwide, making them the most sought after.

From what defines D color diamonds to when they’re worth purchasing and how to unlock their true glory, we’ve explored D color diamonds and their brilliance.

What Defines D Color Diamonds?

Before diamonds are sold, they are evaluated and graded for quality by a trusted gemological lab, such as American Gem Society Laboratories (AGS) and Gemological Institute of America (GIA). As part of this grading process, diamonds are accompanied by a certificate listing factors relating to their cut quality, clarity, carat weight and color. 

Reputable labs grade diamonds for color using a scale from D to Z, created originally by the Gemological Institute of America in the 1950s. D is the highest grade, signifying that a diamond appears colorless both when viewed with the naked eye and under magnification; simply impeccable. 

The top three colors D, E, and F are considered colorless, making them quite desirable as a result. D sits pretty at the top of the color scale with usually no visually detectable body color when viewed by experts in a controlled laboratory setting. 

No matter where in the world you are, you know that a D color diamond is the best diamond color, with the GIA International Grading System the universal language of diamond quality.

Although, not everybody needs to be a diamond expert to see the stark difference between the grades. You can see how much of a difference there is between a D color like this one on Whiteflash:

And a lower color for yourself – a comparison of the two is quite illuminating:

If you do not care about diamonds with the most spectacular sparkle payoff for your engagement ring or are on a modest budget then James Allen or Blue Nile might provide some additional options for your diamond purchase. 

James Allen True Hearts™ collection offers near Hearts and Arrows diamonds that are described as ‘the ultimate expression of love’, although what is more indicative of affection than the highest quality diamond with true clarity from Whiteflash A CUT ABOVE® diamonds?

Admiring a diamond that is incredibly clear is enticing – bound to not catch only the light, but the attention of anybody appreciative of such rarity. Other factors, particularly diamond cut quality, play a substantial role in determining brilliance, fire and scintillation than color in the near colorless to colorless range. 

Making the Most Out of D Color Diamonds

While D color diamonds look extraordinary in most cuts and settings, diamonds of this grade are exceptionally rare and, as such, sell for a premium compared to diamonds with lower color grades. 

Just remember, your setting will need some consideration also. For example, yellow and rose gold will both give the diamond a noticeable tint. A white gold or platinum setting maintains that icy excellence – a formidable choice.

So, with such a warranted price, wouldn’t you want to make sure you’re showcasing your exquisite diamond in a way that unlocks its entire potential? 

Color is of course just one of the critical 4’cs of diamond quality. Make sure all other aspects of your diamond’s quality are also investment grade. True perfection resides in D colored diamonds that are not just colorless but also flawless and perfectly cut. A diamond with a D color grade that’s not very well cut will look far less attractive than a stone with a lower color grade – an injustice to such a spectacular stone. 

To understand how the cut can affect a diamond it is important to have fundamental knowledge of the anatomy, allowing for a better understanding on what geologists are aspiring to while cutting and polishing a diamond. A superbly polished diamond will emit a much greater sparkle than one that has been poorly polished, even if they have the exact same cut.

Above all, when purchasing a D color diamond, we believe cut is king and the right cut can truly complement the stone and ensure that it is nothing short of exceptional. It is well known that D color grade diamonds pair perfectly with a round cut, reflecting and refracting the light perfectly and giving you the payoff you desire.
