Thinking of buying a D color diamond? While D color diamonds look absolutely stunning in any cut and setting, diamonds of this grade are exceptionally rare in nature and, as such, sell for a significant premium compared to diamonds with lower color grades.

If you want the very best of the best and have the budget to match your tastes, buying a D color diamond is an easy way to ensure your fiancé-to-be’s ring looks flawless. 

However, while color is an important aspect of any diamond, it isn’t everything. For most people, buying a diamond with a lower color grade is a better option that will let you spend more of your budget on factors like cut quality, clarity and carat weight.

In the guide below, we’ve explained all you need to know about D color diamonds. Our detailed guide covers everything from what D color diamonds are and how they when look compared to diamonds in lower color grades to how much they cost and when they’re worth buying.

What Are D Color Diamonds?

Naturally, diamonds can vary hugely in color. While most of us associate diamonds with a clear, colorless appearance, most diamonds have at least some level of yellow tinting, ranging form a very faint yellow to a stronger, darker tint that, in some cases, is visible with the naked eye. 

Before they go on sale, diamonds are evaluated and graded for quality by a trusted gemological lab, such as the GIA. As part of this grading process, diamonds are sold with a certificate listing factors such as their cut quality, clarity, carat weight and color. 

We’ve covered these factors and how they relate to the quality of a diamond in our guide to the four Cs

The GIA grades diamonds for color using a scale that runs from D to Z. D is the highest grade, indicating that a diamond has nearly no color and appears colorless both when viewed with the naked eye and under magnification. 

Simply put, diamonds with a D color grade are the highest quality diamonds on the market, at least from a color perspective. They’re also by far the rarest, accounting for a small percentage of all diamonds sold worldwide. 

Other excellent diamond color grades include E color and F color, both of which are also considered to be “colorless” by the GIA. Diamonds that receive a grade of G through J are “near-colorless,” while diamonds with more noticeable color may receive a grade from K through to Z. 

As you’d expect, D color diamonds can look incredible. A well-cut D color diamond can have a bright, icy white appearance that looks stunningly beautiful. 

However, this beauty comes at a price. Because of their rarity, D color diamonds are by far the most expensive white diamonds on the market. This means that unless money is no object, buying a diamond with a lower color grade (such as E, F, or even G or H) is generally a better idea.

We’ve explained this in more detail below, along with side-by-side visual comparisons of D color diamonds and diamonds with lower color grades.

D Color Diamonds vs. Other Grades: A Visual Comparison

As we mentioned above, D color diamonds are famous for their stunning white and transparent color. 

However, while D color diamonds can look absolutely incredible, you don’t necessarily need to buy a D color diamond to get a stunning engagement ring center stone. In fact, when a D color diamond is compared to an E or F color diamond, it can often be hard to tell the difference. 

First, take a look at the image below. On the left side, you can see this 1.02 carat, VS2 clarity, D color oval diamond from James Allen. On the right, you can see this K color oval diamond of the same carat weight and clarity:

The K color diamond on the right is a full seven grades lower on the GIA’s scale than the D color diamond. Side by side under magnification, it’s easy to see the color difference between the two diamonds, even for a non-expert.

As you’d expect, there’s a significant difference in price between these two diamonds, with the D color diamond priced at $4,760 and the K color diamond more than 50% cheaper at $1,970. 

However, how about a D color diamond vs. an F color diamond? Take a look at the image below and see if you can spot any difference in color between the diamond on the left (D) and the one on the right (F):

Even in the oval cut, which shows color quite readily, it’s very difficult to notice any difference in color between the D color diamond and the F color one, even when they’re viewed under bright lighting and 20x magnification. 

Despite looking virtually identical, the F color diamond costs $4,080 — almost $700 less than the D color diamond. 

Now, let’s try a similar comparison with an I color diamond. Unlike the F color grade, diamonds with an I color grade aren’t considered colorless. Instead, the GIA place the I grade in the “near-colorless” range, five steps further down the scale. 

For this comparison, we’ve chosen diamonds in the extremely popular round brilliant cut, which is known for hiding color well due to its numerous facets. 

On the left, we’ve chosen this 1 carat, excellent cut, VS1 clarity round brilliant cut diamond in D color from James Allen. The diamond on the right is this I color round brilliant cut diamond with identical carat weight, clarity and cut grade: 

Even with a difference of five color grades, it isn’t easy to see any significant difference in color between these two diamonds. If you look carefully, you can see that the I color diamond is ever so slightly more yellow. However, the difference is very small, even under 20x magnification.

Despite looking almost identical, there’s a difference in price of close to $1,800 between these two diamonds. The D color diamond on the right costs $6,620, while the nearly identical I color diamond is available for $4,850. 

D Color Diamond Pricing

D color diamonds are the most expensive on the market, as you can see from the numerous examples provided above. 

For a round brilliant cut diamond, you’ll generally need to pay about 10 to 15% more for a D color diamond than you would for a diamond of the same cut, clarity and carat weight with a color grade of G, the highest grade in the near-colorless. 

As you move from a G color grade further down the near-colorless range, diamonds quickly become more affordable. For example, the 1 carat, excellent cut, VS1 clarity, I color diamond we used for the comparison above is nearly 30% cheaper than the equivalent D color diamond.

In short, yes, you get the very best in color when you buy a D color diamond. However, there’s quite a significant cost involved in this, all for a feature that doesn’t have a huge impact on how the diamond actually looks.

Remember, there’s much more to just color when it comes to choosing a diamond. A diamond with a D color grade that’s not very well cut will look far less beautiful than a stone with a lower color grade (for example, a G or H color diamond) that has a higher cut quality.

As we mentioned in our guide to diamond clarity, it’s best to think of your total investment in a diamond ring as a pie. Each feature of the diamond, from color to clarity, cut quality and carat weight, is a slice of the pie. 

The more you spend on any one slice of the pie, the less you have to spend on others, unless you have an unlimited budget. 

The two factors, or slices, that will have the biggest impact on your diamond’s appearance are its cut and carat weight. A better cut means more brilliance and fire; a greater carat weight will translate into a larger, more impressive diamond. 

Both of these factors have much more of an impact on a diamond’s appearance than a perfect color grade.

When is a D Color Diamond a Good Choice?

The answer to this question depends on how much you’re willing to spend on an engagement ring.

If money is truly no object and you have an extremely high budget, buying a D color diamond can make sense. The D color grade is the best of the best, and if you have an eye for quality and want something truly exceptional and rare, a D color diamond certainly fits the bill. 

However, there are far more situations in which buying a D color diamond simply isn’t a smart move. 

First, if you plan to set the diamond in a yellow or rose gold engagement ring, buying a D color diamond is pointless. Once the diamond is set in the ring, the yellow or pink tone of the metal will make the diamond look slightly colored anyway. 

Second, if you don’t have an unlimited budget, buying a D color diamond means you’ll be able to spend less on the factors that actually matter the most, such as the diamond’s cut and carat weight. 

Essentially, you’re paying more for a feature you can’t see with the naked eye, all while giving yourself less to spend on features you’ll be able to see and appreciate.

To help you get the best deal on a diamond, we’ve shared our recommendations for diamond color grades in different cuts.

For Round Diamonds

The D color grade is a good choice for round brilliant cut diamonds only if you have a very high budget that also allows you to spend on cut, clarity and carat weight. 

Just remember that this is really only worth it if you also select a white gold or platinum setting, as yellow and rose gold will both give the diamond a noticeable tint. 

In any other situation, we recommend the H to J color grades for round brilliant cut diamonds in white gold or platinum. For yellow or rose gold settings, K to M color diamonds will offer the best combination of appearance and value for money. 

For Other Diamond Shapes

Just like with round brilliant cut diamonds, buying a D color diamond in another shape is fine if your budget allows you to do so without compromising on cut, clarity and carat weight. 

From a value for money perspective, we recommend the G, H and I color grades for Asscher, emerald and princess cut diamonds. For all other shapes, diamonds in the F, G and H range typically offer the best combination of color and value for money. 

Conclusion

Well cut D color diamonds are undeniably gorgeous. They have a stunning icy white color that’s extremely impressive, particularly when the diamond is very well cut and shows lots of brilliance and fire. 

However, buying a diamond is all about balancing each of the four Cs. While a D color diamond can look amazing, we don’t recommend buying a diamond with this color grade unless you have a very high budget that lets you to do so without compromising on cut, clarity and carat weight. 

We also don’t recommend the D color grade if you want a yellow or rose gold setting, as these metals will cause any diamond to look slightly darker than its true color.
