Are you thinking of buying an E color diamond for your fiancé-to-be’s engagement ring or other diamond jewelry? 

As the second highest grade on the diamond color scale, an E color diamond can seem like a smart alternative to a more expensive D color stone. Like D color diamonds, E color diamonds look almost completely colorless, giving them a beautiful, icy white appearance. 

While an E color diamond can sometimes be a smart purchase, there are a lot of situations in which you’ll be better off choosing a diamond with a slightly lower color grade that still appears colorless to the naked eye.

We’ve covered these situations below, as well as the basics of what E color diamonds are and how they fit into the diamond color scale. We’ve also compared several E color diamonds to a range of diamonds in other color grades to give you an idea of how they look in person.

What Are E Color Diamonds? 

As we covered in our guide to diamond color grades, all diamonds receive a grade between D and Z that denotes their color. D, the highest grade, is reserved for diamonds that do not show any color, even when viewed under bright lighting and magnification.

S through Z, on the other hand, are the lowest grades, and is typically used for diamonds that display an obvious, clearly visible yellow or brown tint. 

As the second highest color grade, E color diamonds are considered colorless. While they may not have quite as strong an icy, transparent appearance as D color diamonds, they appear fully colorless when viewed with the naked eye and under bright lighting and magnification. 

The difference between a D color diamond and an E color diamond is very subtle, with only an expert gemologist with advanced laboratory equipment able to tell the difference. To the naked eye, there’s no visible difference between one diamond’s color and that of the other.

There’s also no visible difference in color, at least to the naked eye, between an E color stone and an F color one. However, in some cases, it is possible to see the color difference between an E color diamond and a stone in a lower color grade, such as H, I or J. 

From a color perspective, E color diamonds look fantastic. Their colorless appearance means they look particularly impressive in white metals like white gold and platinum, which show the color of a diamond more clearly than yellow or white gold.

However, this doesn’t necessarily mean that choosing an E color diamond is always the best decision. As we’ve shown below, the difference in color between an E color diamond and one with a lower color grade can be very small, while the difference in price can be immense. 

E Color Diamonds vs. D, F, G and Other Color Grades

If you’ve previously read our full guide to diamond color, you’ll probably be aware that we don’t recommend overpaying for a diamond with an unnecessarily high color grade. 

Instead, the most effective approach from a value for money perspective is to pick a diamond that looks white in relation to its setting. This can often be achieved by choosing a color grade that’s well below the colorless range. 

We’ve shared some comparisons a little further down the page to highlight this point. For now, let’s start by looking at the differences — or lack of differences — between an E color diamond and a D color diamond. 

For example, look at the two round diamonds below. On the left, we have this 0.80 carat, VS2 clarity, excellent cut, E color round brilliant cut diamond. On the right, we have this diamond of the same cut, clarity and carat weight, but with a D color grade:

Can you see any difference in color between these two diamonds? Even under bright lighting and strong magnification, it’s virtually impossible to see any difference in color between these two diamonds, despite one receiving an E color grade and the other a D color grade.

Despite this, there’s a small difference in price, with the D color stone priced at $3,580 and the E color diamond available for $3,470, or slightly more than 3% less. 

Even when the diamonds are viewed close up in bright lighting, this $110 difference in pricing translates into no visible difference in the appearance of the two diamonds. 

Now, let’s do the same comparison with an E color diamond and a G color one. Below, we’ve compared the same E color round diamond (left) to this G color diamond of the same clarity, carat weight and cut (right): 

Ignoring any issues caused by the different angles of the photographs, can you see any real difference in color between these diamonds? Even close up and with bright light, there isn’t a clear difference in color when the diamonds are viewed from above. 

Even from the side, the difference in color is extremely small — so small that you could never see it with the naked eye:

Just like there isn’t much of a perceptible difference between a D color diamond and an E color one, there also isn’t much of a difference between an E color diamond and a diamond with a G, or even H, color grade. 

Remember, the images above are magnified to 20 times their normal size and lit very brightly to make any imperfections in the diamonds obvious. In real life, the two diamonds pictured above look virtually identical to the naked eye.  

Despite this, there’s quite a significant difference in price between E color diamonds and those in lower color grades — something we’ve covered in more detail below. 

E Color Diamond Pricing

As we mentioned above, E color diamonds are slightly less expensive than D color diamonds, with the D and E color diamonds we used for our visual comparison differing in price by only about three percent. 

However, as you start going further down the color scale from the E and F range, the prices of diamonds begin to drop quite quickly.

For example, the G color diamond we featured above is $3,200 — a full $270, or 8%, cheaper than the equivalent E color diamond. 

This I color diamond, which is certainly colorless enough to look great in a white gold or platinum ring, is cheaper still at $2,720. 

That’s a saving of $750, or about 23% of the price of the E color diamond, all for a diamond that looks virtually identical in any setting (except a halo) outside a gemological lab. 

As we’ve covered before, whenever you save money on one feature of a diamond, such as its color, you increase the amount that you’re able to spend on a more important feature, such as its cut quality or carat weight.

These are both much more visible quality factors for a diamond than its color. Instead of paying for an E color grade, dropping down to a G or H color grade (or, for some settings, even an I or J color grade) can result in you buying a more appealing diamond for the same price. 

We’ve explained this in more detail below, along with our recommendations for round diamonds, other diamond shapes and specific engagement ring settings. 

When Should You Buy an E Color Diamond?

As a general rule, we don’t think it’s worth overpaying for diamond color. This means that there aren’t very many situations in which we’d recommend buying an E color diamond over one with a lower color grade.

If you’re absolutely set on buying a diamond that’s as close to colorless as possible, buying an E color diamond (or even a D color diamond) will definitely get you a highly white, transparent diamond. 

However, this just isn’t necessary — at this point, color is an expensive feature you likely won’t ever notice in real life. 

Instead, a better approach is to buy a diamond with the lowest color grade that will still appear colorless in relation to its setting. We’ve listed our recommendations for this below, with options for a variety of diamond shapes and setting types.

For Round Diamonds

For round diamonds, spending extra for an E color diamond just isn’t necessary. The round cut does a great job of concealing a diamond’s color, meaning diamonds of lower color grades look virtually identical to those in the D, E and F range.

For white metals such as white gold or platinum, we recommend choosing a round diamond in the H to J color range. The I color round diamond we mentioned earlier is a fantastic choice for any white metal, offering a colorless appearance at a lower price than an E color diamond. 

For colored metals like yellow or rose gold, you can drop down to the J to K range. While any diamond in this range will look slightly yellow, even to the naked eye, the color of the gold will make any diamond look slightly colored anyway, meaning this is a non-issue. 

For Other Diamond Shapes

While there’s nothing wrong with buying an E color fancy shape diamond, doing so isn’t a good idea if your goal is to achieve the optimal combination of aesthetics and value for money. 

For Asscher, emerald and princess cut diamonds set in white metals, we typically recommend choosing something in the G to I color range. These diamond cuts all conceal color quite well, meaning a diamond from this range will appear colorless in its setting.

For the above diamond shapes in a yellow or rose gold setting, it’s alright to go down to the J to K range without the diamond appearing overly yellow in relation to its setting.

For all other diamond shapes, we recommend the F to H color grades for white gold or platinum rings, or the I to J color grades for yellow or rose gold settings. 

Conclusion

While E color diamonds can look extremely colorless and beautiful, the differences between an E color diamond and a diamond with a G or H color grade are almost impossible to identify with the naked eye and generally aren’t worth the extra money.

This is also true for D and F diamonds, which look undeniably beautiful but command a massive price premium compared to diamonds in the G to J range. 

As we mention in our guide to diamond color, a diamond’s color shouldn’t take front seat in your diamond purchasing decision. Instead, pick a diamond with the highest cut quality, then choose a color grade that ensures it looks colorless in relation to its setting.
