James Allen: Best diamonds imaging technology, largest diamonds inventory store, along on this with:

Blue Nile: Head-to-head in inventory with JA, with more options to smaller diamonds.

Whiteflash: The premium diamonds store! House of A CUT ABOVE®


It has always been fascinating to all of us; the ability of women to discriminate among colors and actually seeing more color gradations than men. And for this specific reason, color shouldn’t be taken lightly; especially when it comes to diamond color! Check this reference if still in doubt.

Women vs Men color perception

Color is considered to be one of the main 4Cs of the diamond characteristics. It’s also one of the most important aspects to look at when considering buying any diamond.

We said “one of” and not the most important, because we know for a fact that the most important factor among the 4Cs of a diamond is the Cut!

In this article, we will examine a diamond color thoroughly and will take a look at a diamond color chart that will explain in detail each color and the letters associated with it. Shall we?

Diamond color is graded on a scale from Colorless to Yellow; colorless diamonds being higher priced (and supposedly higher quality). 

On a diamond certificate or when looking at diamond characteristics online, you will clearly see single letter notations starting from D for colorless (most valuable) down to J for the lowest graded colorless diamonds. 

There are more color grades on the scale down until Z, and beyond the Z range, some of the exotic colors exist (most common are yellow and brown)! It’s worth mentioning though, that these have less value than other diamond colors!

And as the great Jerry Lee Lewis sang once on breathtaking colored diamonds in the famous classic Big Blue diamonds:

Big diamonds, big blue diamonds, on her finger
(On her finger)
Yes, ‘stead of a little band of gold
(Big blue diamond)
Big diamonds (big blue diamonds)
Big blue diamonds (big blue diamonds)
Tell a story of the love
That the one man could ever hold
(Of them all)

When talking about rare specimens, these gems come in every color of the spectrum, including blue, green, pink, and red; the rarest colors ever found. However, not all fancy colors are considered to be highly priced.

Look at this D-color diamond for example. On a standard diamond color scale, this diamond has absolutely no color, that’s why it’s priced at $7,590 (1 carat), while an “almost” identical gem in all other factors (clarity, cut, polish, and symmetry) but with a J-color is priced at almost 60% of the D-color one, for the sole reason that it has a J color!

So what’s the deal here exactly?

One point though, we focus in this article only on the common diamond colors (D to K). However, technically speaking, there are way fancier diamond colors which we will not be getting into details in this blog.

Since the Wikipedia chart gets into many details that are not really necessary for a lot of our readers, we took the liberty to create our own Diamond Color Chart (below) where you can see actual photos of diamonds and not just an illustration.

We believe that seeing the actual photos will give you a better idea of the small differences between each step in the grading system.

Is it Always “Higher Color Diamond” is Better?

While most retailers or online diamond sites will try and encourage you to get the highest diamond color grade possible and convince you that it is the preferable choice for the beauty of the stone, the truth is far away from that.

For instance, James Allen claims that “when shopping for a diamond, it is generally preferred to have the least amount of color possible”. Well, “generally” doesn’t mean always! Since they later mention on the same page that “Most people find it very difficult (if not impossible) to tell the difference from one color grade to another. The difference in price, however, can be significant.”

The reality is actually much closer to the 2nd statement. Therefore, unless you are comparing the diamonds, side by side under a proper light and on a white background, it will in fact be impossible to tell the difference between 2 diamond colors _that are just one-grade apart_on the diamond color scale. An example would be the difference between G and H.

Anyhow, there’s absolutely no chance that a naked eye could spot the color difference between 2 stones when looking at each one of them individually!   

Even when you take 2 gems that are a bit further apart (for example an F and H) you will likely only notice the difference when you hold the 2 diamonds side by side? 

Diamond color is subjective and doesn’t stand as a science by itself, so don’t ever think that someone can tell you exactly what color is this diamond without comparing it with another set of diamonds (that their colors are known).

Use a Diamond Color Chart And See For Yourself

Still not convinced? Check out our diamond color chart below that shows actual diamond photos from James Allen’s own diamond color chart and look at some colors that are adjacent to each other. Can you tell the difference?

Even on James Allen Color Scale, which is an illustration that in our opinion overstates the differences,  you will still have a hard time seeing the difference.

What some jewelers might not tell you (and to be honest, we consider this as negligence), is that there are other factors that affect the perceived color of a diamond, like fluorescence. Even the setting that the diamond will be set in affects how the color will look on the actual ring. If the setting is yellow gold even an E color diamond may look slightly yellowish so why spend extra money on that?

Our Own Diamond Color Chart With Real Diamond Images

Here is a diamond color chart that we put together showing similar diamonds (all factors are constant) varying color only. All diamonds here have been selected to be between 1.0 and 1.05 carats, ideal cut, VS1 clarity, and round shape.

All the diamond images below are real diamonds listed on James Allen (at the time of writing this blog), each image is clickable zooming into a larger view for each diamond.

As you’ve probably noticed, the only major difference between the gems is the color.  See for yourself if you can tell the difference between two adjacent grades.

Color Grade
DescriptionSample Image

D Colorless diamond are one of the most rare diamonds ever, they are truly colorless (along with E grade).
D Grade is also one of the most valuable grades you can ever find.
Most gemologist can tell the difference between D & E grades by comparison side by side, only a few of them can detect that in naked eye without having the other grade in hand.
E grade is coloreless as well, can't detect any color on it, it's valuable as D grade (almost).
You need an experienced gemologist to tell the difference between D & E as stated above.
F is colorless; almost!
Because when a gemologist looks at an F grade diamond as faced down, he/she can notice a very (undetectable) amount of color.
D, E & F grades should be in set of white gold or platinum, because color is reflected in yellow gold, it won't appear nice because it will negate the colorless effect in those grades.
GNear Colorless
G is the first line of near colorless grades.near colorless grades.
G is the most expensive grade among the near colorless grades, thus, you may see more of I & J in retail markets
Also note that price tend to decrease 10%-20% from grade G down to J. So a $1000 J diamond may cost around 60%-80% more if it was G grade.
HNear Colorless
H is a bit less expensive that G, but still more than J & I.
It can set (along with all near colorless grades) with platinum or white gold settings.
INear Colorless
You will see more & more of I & J in retails because they are much cheaper than other graded colorless & near colorless diamonds.
Roughly speaking, I & J are almost half the price of D grade diamond.
JNear Colorless
Same as I, it's the cheapest (cheaper that I), most people prefer to get it since it's the most affordable near colorless diamond.
KFaint Color
Yes, colorless & near colorless grades are much more expensive, but the K grade colored grade has a huge audience of fans, a lot of people love to see some color in their diamond, so they go shop for a K grade diamond, which shows a decent amount of color (compared to previous grades).
Mentioning the price, K grade is almost half the price of G grade diamond.

How Diamond Color Impacts Price

In spite of us mentioning this in the table briefly, we’ll be explaining_in more details_the effects of diamond color on price.

While there is a jump in price between each of the colors on the scale, the single largest jump is found to be between the G and H colors. Actually, there is no obvious technical reason for that, besides, both are still near colorless diamonds and there is no way an untrained eye can tell the difference between them.

Blue Nile Ring 2

To demonstrate, check out those 2 diamonds (with actual photos) on the James Allen website along with a “Virtual Loupe” that gives you the unique opportunity to see diamonds in detail. They are very similar except that this one is an E-color diamond and this one is an F-color diamond.

You can zoom in as much you want, can you honestly tell the difference? (Well, spoiler alert, neither can she!)

Also, read our Guide to Diamond Pricing for a better understanding of how jumps between colors relate to pricing.
