If you are filthy rich, then yes, why not? Spend 17K on a 1 carat D flawless diamond, like this one on James Allen.

But if you want to learn how to get the best bang for your buck when getting a diamond, then you might find this post useful, because we will see the “insane” price of a D flawless diamond, then understand how to get a better diamond for your money shortly after.

Let’s start this off by shedding some light on why this is not such a great idea as well as uncovering the real price for such gems and the true value of getting one!

Notice that we’re talking about the two highest grades possible, in terms of color (D grade), and clarity (flawless). To put this in perspective, let’s take a quick look at where these grades fall…

D Color Grade – Where it Stands?

On Diamonds Color scale, and according to GIA standards (that most labs followed after), diamonds are graded from D (being the most colorless) to Z (note all color grades after K start to show some yellow).

Here is the grades scale; grouped by the percentage of color in each group for your reference:

We believe it’s obvious that since D is the first grade in the scale, it’s known that the D Colorless diamonds are considered one of the rarest diamonds ever, it’s utterly colorless (along with E grade).

It is also one of the most valuable (in terms of being expensive only!) grades you can ever find. 

P.S. Even gemologists can NEVER tell the difference between D & E grades by just looking at one of them alone, they have to hold them side by side to tell a difference without any guessing! So don’t ever expect someone to tell what color is your diamond by just looking.

Well, D grade is really fascinating and all, but do we actually recommend it?

Generally, and in order not to spend money on something you can’t see, we recommend our readers to get a G color (sometimes even an H grade). These two grades will not show any yellow color to the naked eye.

Having that said, it’s obvious that the D color is waaaay too high from the recommendation you will hear from any expert, you’re talking about at least 3 grades higher from a color that is guaranteed 100% to appear completely colorless.

Flawless Clarity Grade – Where it Stands?

Diamonds are created under tremendous amounts of pressure and heat. Under a 100 miles deep, and a 2,000 Fahrenheit temperature, with an exerted pressure of more than 70,000 pounds per inch square, too much physics we know!

In short, under these circumstances, a diamond with some flaws (on its surface) will definitely be made!

These imperfections are called “diamond inclusions”.

Diamonds with no inclusions are extremely rare; that even some jewelers go throughout their whole lives not seeing a single free-inclusion diamond! 

This brings the question, what percentage of diamonds has almost ZERO inclusions? It’s safe to say that more than 99% of diamonds can’t make it to “Flawless”! 

JamesAllen, the biggest online store for diamonds; having a wide collection of more than 170k diamonds, has less than 400 flawless diamonds (diamonds without any inclusions) as you can see here.

That’s almost 2 in a thousand! Wonder why?

Here is the clarity grades scale for diamonds:


The flawless clarity grade is similar to D in color, it’s very rare and stands on TOP of the clarity grades scale! We believe it’s clear now why it’s so expensive, and to be honest, not recommended at all!

Because in order to get an eye-clean diamond, in most average weight diamonds (around 1 carat), you won’t need to go further than SI1, and in higher carats, the VS2 diamond is pretty much eye-clean!

Can you see where the FL stands on the scale? It’s five grades higher than the recommended to get an eye-clean diamond. 


What is 1 Carat D Flawless Diamond Price?

We took the liberty to perform a simple search in order to have a fair estimation for this gem. We are fixing all other factors and changing the color and clarity and note their contribution to the total price. Ready? Let’s dive in:

Carat: 1

Color: D

Clarity: FL (flawless)

Cut: Ideal (Excellent)

Shape: Round

Polish & Symmetry: Excellent

Fluorescence: None

Grading Lab: GIA or AGS

Being the largest online stores, we will get the prices from both James Allen & Blue Nile.

The outcome of doing this search on James Allen’s was only 4 diamonds; priced between $16.4k and $17.7k (yes, you read it right, $17k for a 1-carat diamond!)

Carrying out a similar search on Blue Nile resulted in only one diamond; priced at $17k!

Reading our article about Diamond Price per Carat will give you a general idea of the average (and reasonable) price for a 1-carat diamond, which ranges (excluding edge diamonds) between $3.5k and $6k.

We’re talking about triple the highest reasonable price expected for a 1 carat diamond! And to be straight-forward, it’s insane to put all that amount to such a diamond.

Why Buying a D Color, Flawless Clarity Diamond is NOT Recommended?

We’re not really saying that it’s not recommended, we just believe it’s a waste of money to get such a diamond!

When it comes to diamond shopping, you know you have to make your buying decision and your choice of characteristics based on what “really” makes a difference in the appearance, sparkle, and scintillation of your stone, other than that, it’s really just a waste of money!

To get the best bang for your bucks, you need to understand that these are nothing but some crazy “overpriced” characteristics that you will regret overspending money on!

You want a diamond that doesn’t show ANY yellowish color, right?

Cool, G grade is more than enough to achieve that!

Even if you’re way too sensitive to yellow, the highest we would advise you is to get an F color; since it’s graded by GIA to be colorless (so it really has no color in it)!

You want a diamond that doesn’t have any visible inclusions or any blemish that affects its brilliance, right?

Great, start with SI1 grade, and if you’re just too sensitive, the VS2 would be more than perfect!

Why won’t you hear this in your local jewelry store?

Diamond salespeople will always try to convince couples to get the highest color to avoid any yellowish, ironically, this highest grade will be the highest color they have in store!

After talking to a diamond retailer, you’ll probably be left more lost about the perfect option for your stone’s color! It’s worth mentioning, though, that a diamond color needs to be inspected by an expert (probably a 3rd party) and that it sure isn’t easily seen by the naked eye unless it’s compared with a known-grade diamond.

Regarding clarity, if you really want a clear diamond without any visible inclusions and with brilliance out of this world, then we urge you to invest in the stone’s cut, rather than jumping to an insane grade like the “flawless”!

However, if money is not really an issue for you, skip this and get the clarity you want, but for normal people with a tight budget, please don’t even think about going beyond VS1, even for extreme clarity measures, VS2 is eye-clean, and VS1 is even cleaner.

You don’t really need anything higher than that (unless you’re getting 4 or 5 carat diamond, to make a full statement here).

What Diamond Characteristics to look for then?

Of course, we would never just advise you to not get these grades and keep you hanging!

Based on years of experience in this field, inspecting, and recommending thousands of unique diamonds for our readers, we gathered the best (and most recommended) grades to guide you when you’re diamond picking:

Cut: Always go for Ideal / Excellent cut, even for a lower carat (keep in mind, Cut is the most important factor of any diamond).

Clarity: In most cases, SI1 will be eye-clean. For a safer choice, VS2 is your gem! If you’re getting a relatively large diamond (+1.5 carat), it’s better to stay at VS2 since some types of inclusions can be visible in SI1 (for bigger gems).

Color: Stick to G color, G is perfect; it has no yellow seen by an untrained eye and depends on your setting color, you can also go H in some cases, don’t go crazy with this. Color is only one factor of four!

You better be spending your extra savings on other characteristics; a higher cut diamond for instance; since it’s the most important factor among the 4Cs.

Carat: A matter of preference, just don’t invest in carat before guaranteeing the above-mentioned grades.

Polish & Symmetry: Excellent (that’s the case in 99% of Ideal cut diamonds).


I hope you reached this post because you were just curious to know the price of a 1 carat D color Flawless clarity diamond and nothing more, you are not intending to get one.

Getting such extremely high grades is purely wasting your money on what doesn’t make that difference you think to your diamond. 

Keep this in mind: Why overspend on a D color, when you will never be able to see the added color (even for higher grades like G or H) with the naked eye?
