Diamond Color

Color grades range from D (colorless) to Z (yellow / light brown). Unlike the diamond cut the color of a diamond is a great place to save money. I will talk about this in a moment. The color grades D, E and F belong to the colorless category, the color grades G, H, I and J belong to the near colorless category and the color grades from K onwards belong to the Faint Color Group.

About the diamond color grading system

The more colorless a diamond is, the better its light absorption and thus the visible sparkle. For this reason people usually desire the more colorless diamonds. Most diamonds in nature contain a slight hue in their body. Really colorless diamonds are very rare and are sold at a high premium price. However it is very difficult to distinguish between even several color grades so that is is definitely not necessary to go for the best color grade.

Just have a look at the examples below taken from James Allen.

Colorless Diamonds (D-F):

Diamonds within the colorless range are the rarest diamonds. D/E colored diamonds will display virtually no color. They are icy white. F colored diamonds on the other hand display a nearly undetected amount of color but only when viewed face down by a professional gemologist.

I myself have never been able to distinguish between a D and F colored diamond when they are not directly next to each other in the face-down position.

Near Colorless Diamonds (G-J):

Diamonds within the near colorless range appear colorless in the face up position. However when viewed face down near colorless diamonds exhibit a slight amount of body color. In order to see that body color the diamond has to be viewed against a perfectly white background.

However, once the diamond gets mounted onto a ring setting the color will not be detectable by a layman. Therefore, near colorless diamonds are the best option for getting the biggest bang for your buck!

Faint Color Diamonds (K):

Diamonds within the faint color group show a slight hint of color in the face up position. They are a particularly good choice for people who like the warmer look of K colored diamonds. They are also a great way to get the best bang for your buck for people who want to set their diamond onto a yellow gold ring setting. As diamonds pick up quite a lot of the color of a yellow gold ring setting it would be a waste of time to overspend on color:

In this article I will be talking about the white diamond color grading system shown above. It basically applies to all white diamonds.

As you might know, there are also the so-called fancy colored diamonds which have colors like blue, organge, pink and red. Here I will only give you a brief outline of the classic, colorless white diamonds but you can read my post on the fancy diamond color grading system here.

Which diamond color grade to choose?

If you have no idea where to start, the most popular color is the G color grade. But this does not mean that you have to choose a G color grade to get the biggest bang for your buck. In fact I would recommend to never choose a color grade better than G! The reason is quite simply that as a normal customer you would most likely not even see a difference between a G and a D color if they were held next to each other. You would end up paying way more for a premium feature which you cannot even appreciate with your bare eyes apart from the color grade you will see on your grading report.

On the pictures below you can see two different diamonds. The one on the left is a D colored diamond with the face-up view and back view and the one on the right is a G colored diamond with its face-up view and its back view:

Now, I guess that you can see a difference between both diamonds in terms of its color. But you have to consider that you can only see it because both diamonds are shown in 10x magnification and are directly compared to each other! Furthermore you are comparing loose diamonds to each other! Most diamonds, however, are bought to be mounted onto a ring setting. A diamond mounted onto a ring will invariably pick up some of the metal’s color!

If you did not compare both diamonds to each other like that the G colored diamond would appear to be completely colorless. Even diamond grading experts from GIA and AGS who are doing nothing else but grading diamonds all day long can only estimate the color of a diamond by comparing the diamond to a set of master diamonds. This is done under best lighting conditions you can imagine. I know from experience that many people would even consider an I or even J colored diamond to be colorless if they would not directly compare it to a D colored diamond!

So, which is best color grade to choose? It will largely depend on what kind of diamond and what kind of ring metal you intend to use. I am going to explain it in an orderly fashion.

I want you to get the biggest bang for your buck which means that you get a diamond that looks completely colorless but in fact does not have a D color grade. In fact you should get a diamond several color grades below that which will cost you much less. This way you will have more money to spend on the cut and carat weight of a diamond. As most diamonds are either mounted onto a yellow gold ring settings or white gold ring settings you have to be very well aware that your diamond will pick up some of the color of your ring metal.

A diamond will invariably pick up some of the color of the ring setting

Diamonds in yellow gold settings pick up more of the yellow gold hue compared to diamonds set in a white gold ring setting. For this reason, diamonds set in yellow gold don’t have to have such a good color grade as you would choose for a diamond set in a white gold ring setting.

Just have a look at these examples of diamonds on yellow gold ring settings and these examples of diamonds on white gold ring settings. It is quite apparent that diamonds in yellow gold ring settings absorb much more of the ring setting’s color. You can take advantage of this knowledge and save yourself quite some money!

Furthermore the diamond shape will have an impact on the diamond color as well. The proportions and facetting patterns of various diamond shapes differ. For this reason certain diamond shapes are more prone to showing off their body color.

The round cut diamond is the diamond shape the least prone to showing off its body color. Princess cut diamonds, emerald cut diamonds and asscher cut diamonds are a little bit more prone to show of their body color and therefore it is advisable to take one color grade higher than you would choose for a round cut diamond.

All the other diamond shapes especially the elongated diamond shapes like oval cut diamonds, marquise cut diamonds and pear cut diamonds are even more prone to showing off their body color. In these shapes the body color can be easily seen near the pointed tips. You will have to chose an even better color grade for these diamond shapes.

During the years I have come to the conclusion that according to your diamond shape and the ring metal you use these are the best color grades to choose:

Best color grades for your diamond

I guarantee you that if you use the color grades according to the table above every normal person will think that you bought a perfectly colorless diamond.

Price differences between different color grades

The best thing about choosing a diamond color as in the tabe above is that you get to save a lot of money! You are not “wasting” money on a premium feature which you won’t be able to appreciate with your bare eyes, anyway!

Of course, I do be well aware that many people want to get the best diamond color because this is supposedly a matter of honor. And this is absolutely fine. I just want to make you aware that you can save a lot of money with regard to the diamond color if you want to.

All the other 3Cs being equal you can clearly see that you pay a large premium for the D color because it is very rare. A diamond with an H color set into a ring setting will appear completely colorless, too. And will save you a lot of money!

Diamond color regarding larger sized diamonds

Large diamonds trap more body color in their bodies than smaller sized diamonds. If you took a 0.5 carat diamond and a 3 carat diamond with the same diamond color and directly compared it to each other you would likely find the smaller diamond to look more colorless.

If you buy a really large diamond (from 2 carat upwards) you might consider getting a color grade better than you would normally have done according to my “best bang for your buck color grade table” above.

Blue Fluorescence

The last important thing to know about diamond color is that some diamonds exhibit fluorescence. Whether and to what degree a diamond exhibits fluorescence is always noted on the grading report.

If you don’t have much money to spend and want to buy a diamond in the I-K color range you might consider buying a diamond with medium blue fluorescence. Please be aware that I do not recommend buying diamonds with fluorescence apart from diamonds in this particular color range. You can find more information about how blue fluorescence might help you boost a diamond within the I-K color range in my post about diamond fluorescence.

  1. Hi sebestian,I am about to take diamond for astrological purpose.Astrologer told me to take 1 carat brilliant cut,K color,clarity Vs1/Vs2. I will put it in a gold ring.Does the specification worthy for my purpose?Please suggest me your views.Thank you in advance.

  2. Dear Sebastian,
    I am about to purchase an engagement ring (setting: solitaire, platinum ; stone: round cut). First of all, I want to point out how helpful your site was! Much obliged.

    I have a few questions you are most certainly will be able to address: It appears to me, the medium blue fluorescent diamonds in the color grades I-K are slightly more expensive than the equivalent color grades without any fluorescence. I guess I am wondering whether a K colored diamond with medium florescence would be preferred over a J color graded diamond lacking any fluorescence? Would they appear similar in terms of color? Would a K colored diamond with medium florescence be acceptable for a platinum ring for the inexperienced eye?

    Thank you so much! 🙂

    • Hi Eddy,

      Thanks for your wonderful feedback! To answer your question: The slight price difference you noticed could be dependent on a few other factors like cut, carat, and clarity. As far as I know, a J colored diamond would still be a better choice especially if your opting for a lighter gem.

      This is because the diamond color whitening effect of medium fluorescence is only visible in daylight, an environment with UV light, and not in all lighting conditions. Thus, in general, when not subjected to UV light, a non-fluorescence J color diamond will look a little bit brighter than a medium-fluorescence K color diamond.

      I would also recommend choosing the H – J color range and avoiding K color if you’re considering a platinum ring. Take a look at this article to know more: http://yourdiamondteacher.com/diamond-4cs/color/best-diamond-color-for-platinum-settings/

      If you have further questions, feel free to write to me anytime. Cheers! 🙂

  3. hello i have the option of either 1.5 carat K colour diamond or 2 carat O colour diamond . both have very good cuts and s2 clarity. which one should i go for and what setting should i use ?? yellow gold or white gold??

    • Hello Harshita,

      It’s advisable to see the diamonds before buying, especially in the SI2 range, so you can make sure that it’s eye clean. And for size and color, it actually depends to your liking. Just bear in mind that with bigger diamonds, body color is more evident.

      If you want to wash out the yellow, then you may opt for the K color and use a yellow gold setting because the gem will appear lighter against a darker backdrop. But if you’re good with yellow and would like to highlight it even more, then you may use white gold.

    • Hello Rosa,

      It’s good that it has excellent cut and it’s eye clean, but you don’t really have to go for the highest color and clarity grades as I’m sure you’ll find superb quality in the F-H and VS1-VS2 range as well. 🙂

  4. i am choosing between an si1j cushion or a si2h roundth both no fluoresence which one would u choose

    • Hi Shawna,

      I would choose the latter for three reasons: First, round cuts produce better sparkle. You just have to make sure that it has excellent or ideal cut. Next, H color is a much better color than J (if you want a bright diamond), but it’s not too expensive like the D-F range that’s also considered as overkill. Lastly, both SI1 and SI2 can be eye clean diamonds, so if the SI2 gem is eye clean, then you’re going get a more affordable gem without visible inclusions. 🙂

  5. I am looking for a light champagne diamond (not brown) but with brown or rosey tones rather than yellow/green tones. Fancy colors are too dark. Which grade is most likely to give me this – I have been looking at O to Z diamonds.

    • Hi Sylvia,
      yes, if you want to have a champagne diamond, a diamond within the fancy colored range will indeed be too dark for you.
      Basically, champagne colored diamonds are diamonds with the hue “light brown” or “light pinkish brown”. Quite apparently, you prefer the “light pinkish brown” diamonds. “Light pinkish brown” diamonds are more expensive and even rarer to find than just “light brown” diamonds.
      The normal color scale from D-Z does not apply to champagne colored diamonds. On older grading reports you will find information like “w to x range” and on newer grading reports you will only find the information “light brown” or “light pinkish brown”.
      In the end, you must trust your eyes and decide whether you like the color or not. There is no specific range that will give you the perfect answer because there are different kind of champagne hues. The “light brown” hues that I find to be champagne-like and that are not within the fancy color grading scale are usually within the W to Z range.
      With your preference for a rosey champagne diamond the range of O to Z will certainly be right. As long as your diamond is “light brown” or “light pinkish brown” your diamond will certainly belong into the champagne category.
      If you have any more specific questions, you can always drop me a mail!

    • Hallo Rick,
      yes this is absolutely okay if you wanna make a good deal. A diamond picks up some of the ring setting’ metal color. This effect is the strongest with yellow gold.
      Thus, it would not make much sense to pick a better color grade for your specific constellation of diamond and ring setting.
      And don’t worry: The diamond will still appear to be colorless.
