Bottom Line:  A low clarity eye-clean diamond will look identical to a flawless diamond assuming all else is equal (yet will cost far far less). At present the only vendor offering sufficiently high quality images on all of their diamonds for reviewing clarity is James Allen. With their technology, you are able to find this beautiful SI2 diamond that saves you almost 25% over a mediocre VS2 like this

Nobody Can Tell the Difference Between SI2 and VVS2


The Greatest Myth About Diamonds

The greatest myth about diamonds is that they are a smart investment.  Edward Jay Epstein, in his industry-shaking exposè on the “Diamond Invention” entitled “Have You Ever Tried to Sell a Diamond?” clearly and emphatically puts this idea to rest.

I recommend any prospective diamond buyer first read this article from start to finish.  It’s important to be in the right frame of mind when making such a major purchase and not be influenced by all the magic and emotion thrown at you from DeBeers advertising.

Diamonds Are Retail Products

Diamonds are a retail product just like any other.  The product goes through various stages of production and distribution (mining, polishing, distribution, retail, and finally customer).

As the diamond changes hands, each participant takes their cut.  By the time the finished product ends up in the customers’ hands, the price is sufficiently inflated that you could never sell it without losing money.

If cars lose 15% when they leave the lot, then figure most diamonds probably lose at least 30-40% when they leave the store.

The Most Common Mistake

I began with this because the most common mistake people make when buying diamonds is they purchase a diamond with a clarity grade that is simply too high to appreciate in order to buy a “good investment.”

Lets review the basics really quickly.  The scale of diamond clarity (GIA scale – other labs have added some other interim grades) goes like this (from best to worst):

Internally Flawless (IF), Very Very Small Inclusions 1 (VVS1), Very Very Small Inclusions 2 (VVS2), Very Small Inclusions 1 (VS1), Very Small Inclusions 2 (VS2), Small Inclusions 1 (SI1), Small Inclusions 2 (SI2), Inclusions 1 (I1), Inclusions 2 (I2).

The chart below contains real magnified sample images of GIA certified diamonds.  I have chosen to use Asscher Cuts & Emerald Cuts for the sample images since these step-cut shapes show inclusions the clearest.
It should become clear from the chart below why it is so crucial to only buy from a online vendors (Like James Allen and Brian Gavin Diamonds) that provides you with high quality images of their diamonds.

Clarity Grade Description Sample
IF – FL Internally Flawless / FLawless – No internal or external imperfections.  Flawless diamonds are extremely rare.If you see anything at all on diamonds with a Flawless clarity grade, you can be assured that it is merely dust.  For example, if you click on the sample image to the right, you’ll notice on the left-most edge, there is a tiny speck.  That tiny speck, if it were an inclusion inside the diamond would probably render the stone a VVS2.
VVS1 Very Very Slightly Included (1st Degree) – Diamond clarity inclusions rated VVS1 are not visible at all under 10x magnification.  These tiny pinpoints can only be seen under a powerful microscope.For the VVS Clarity grades, I don’t think it’s worthwhile to offer a sample diamond, since anyway, it would be impossible to tell using James Allen’s magnified images whether a certain dot is an inclusion or a piece of dust.  Furthermore, a regular photograph, even a magnified one, can only focus on one level of depth. If a VVS-size inclusion is in a diamond, and the image is focused on a different layer of depth, there is no chance the pinpoint inclusion will be visible. Sample image of VVS1 diamond clarity inclusion
VVS2 Very Very Slightly Included (2nd Degree) – Diamond clarity inclusions rated VVS2 are sometimes just barely visible under 10x magnification (standard jeweler’s loupe).  When they are visible, they are quite difficult to find and can often take quite a while to locate. Generally, however, you need a gemological microscope to identify a VVS2 inclusion since, often, the inclusion pattern is not one larger speck, but a few separate VVS1 sized spots that collectively equal a VVS2 clarity grade.  Since each of the individual spots are too small to be seen with a jeweler’s loupe, one needs a microscope to identify them. Sample Image of VVS2 Clarity Inclusion
VS1 Very Slightly Included (1st Degree) – VS1 diamond clarity inclusions are just barely visible under 10x magnification (standard jeweler’s loupe).  When looking for VS1 clarity inclusions with a loupe, it can sometimes take a good few seconds until the pinpoint is located. Unlike VVS2 clarity inclusions, a microscope is never needed to locate a VS1.  As you can see on the sample diamond to the right, a VS1 clarity inclusion is still quite small and will never be visible to the naked eye.  If you have trouble seeing the inclusion in small sample picture to the right, click on the photo to enlarge it. Sample Inclusion of VS1 Clarity
VS2 Very Slightly Included (2nd Degree) – VS2 clarity inclusions are almost always easily noticeable at 10x magnification (standard jeweler’s loupe).  Occasionally, the inclusion will be located in a difficult-to-spot location, but otherwise, the inclusion is large enough that it can be spotted quickly under magnification.VS2 Clarity inclusions are almost always clean to the naked eye.  The sample photo on the right is somewhat of an extreme example.  I specifically looked for a VS2 that was black and in the center of the stone to more easily illustrate the size of a VS2 inclusion.  The inclusion in the sample photo might very well be visible to the naked eye as a result of it being black, in the center, and in an emerald cut (which do not mask inclusions at all).
SI1 Slightly Included (1st Degree) – SI1 Clarity inclusions are easily found with a standard jeweler’s loupe at 10x magnification.  With most shapes (to the exclusion of step cuts like Asscher and Emerald Cuts), SI1 clarity inclusions are almost always clean to the naked eye.As with the VS2 sample above, the diamond chosen for the sample picture of an SI1 clarity inclusion is an extreme example chosen to show the maximum size and worst possible color of an SI1.  One must remember that a clarity grade can be based on many different inclusion points within a diamond.  It is less common (especially for SI1 and lower) that the clarity grade is based on one concentrated inclusion.  Usually, there are a number of smaller spots and clouds of tiny spots that make up the clarity grade.  In these cases, since each individual inclusion is very small, the diamond looks clean to the naked eye.
SI2 Slightly Included (2ndDegree) – SI2 clarity inclusions are seen clearly and obviously with the help of a jeweler’s loupe.  With step cuts like Emerald and Asscher cuts, an SI2 clarity inclusion will most likely be visible to the naked eye (as is the case with the diamond in the sample photo on the right).  With other brilliant shapes (basically all the other common shapes), an SI2 clarity inclusion will usually be clean to the naked eye.As with the SI1 sample photo above, I specifically chose a concentrated black center inclusion to illustrate just how bad an SI2 can get.  A center black SI2 on an Emerald Cut is about as bad as an SI2 as there is.  As I mentioned above regarding an SI1, in most cases, the SI2 clarity grade is made up of several (or many) smaller inclusions.  In these cases, since the SI2 is spread out all over the stone, and not concentrated in any one area, the diamond is usually eye clean.
I1 Included (1st Degree) – I1 clarity inclusions are even more obvious and clearly seen than SI2 clarity inclusions.  Most I1 inclusions are visible to the naked eye – even on brilliant cuts.  I1 clarity inclusions are so obviously visible on step cuts (Asscher Cuts & Emerald Cuts) that you rarely see them produced.  In fact, at the time of this article’s writing, James Allen had a total of only six I1 clarity Emerald cuts 0.90 carats and higher.  They had no I1 clarity Asscher cuts in stock (any weight).  This is why the sample picture to the right features a princess cut diamond and not a step cut. Just because the sample picture on the right is as hideous as it is doesn’t mean you can’t find a perfectly eye-clean beautiful I1 clarity diamond.  As I mentioned above, most clarity grades are comprised of several to many smaller inclusions spread out over the area of the diamond.  In such cases, the I1 clarity inclusion will be much less noticeable to the naked eye, if at all.  Concentrated black inclusions in the center of the diamond are the exception, not the rule.  I show them here in this chart simply to show how bad each clarity grade can get.

Invisible Features

I worked in the diamond business for 6+ years.  If you gave me a diamond with a VVS2 clarity grade, it might take me a few minutes with a 10x powered loupe to find the actual pinpoint of an imperfection that is the “Very Very Small Inclusion.”

I could find a VS1 in less time, but it’s only marginally larger than a VVS2.  VS2s clarity grade inclusions can be spotted right away with a 10x powered loupe, but are usually invisible to the naked eye.

When you reach SI1 and SI2 clarity grades, however, you begin to find a much higher concentration of diamonds with eye visible inclusions. Because of this, it is imperative to limit your search to vendors with high quality photos. Of course, we encourage you to reach out to us and we’ll gladly help you choose the perfect SI1 or SI2 that is eye clean.

Now, if a diamond is simply a product that has features that you want to benefit from (i.e., its beauty), why pay a lot more for features from which you will never benefit?

Sliced Features

Think of your total investment in a diamond ring as a pie.  Each feature of the diamond has its own slice of the pie and the more you spend on a feature the larger its slice (and therefore, another slice or slices must become smaller).

Wouldn’t it make sense to apportion the largest slices to the features you can actually derive benefit from? All you have to do for the other features is make sure the slice is sufficiently large that it doesn’t detract from the beauty of the diamond.

Unequal Inclusions

Unfortunately, though, things aren’t quite as simple as I’ve made them seem.  An important thing to remember is that not all inclusions are created equal.

Some inclusions are shiny and some are almost completely clear.  Some inclusions, though, are dead white and some are even stark black.  Some inclusions are dead center in the middle of the diamond, and some are pushed so far off to the side, they aren’t noticed.

The clarity grade mainly takes into account the size of the inclusion, and rarely considers the color and opaqueness of the inclusion nor its position.

Cutting-Edge Photography

Thankfully, James Allen has some truly fantastic cutting-edge photography that will allow us to review actual clarity examples with a tool they call 360° Diamond Display Technology that provides 18x magnification around the entire stone.

Diamond Clarity – A Real World Test

The first diamond I want to review is a 1.00 carat I1.

Figure 2: I1 at 18x

Figure 2: I1 at 18

This diamond is a perfect example of the great value you can find if you take advantage of technological breakthroughs like James Allen’s 360° Diamond Display Technology or Brian Gavin Diamonds’ high quality photographs.

In Figure 1, which is at 9x magnification, you can barely see anything.  Had I not marked the inclusion in red, you probably would not have noticed it at all.

The inclusion is only slightly opaque, but best of all it is completely on the perimeter of the diamond.  A skilled jeweler could easily cover this with a prong to give your diamond the appearance of being completely clean.

Hidden Inclusions

In Figure 2, you can see the same diamond, but with 18x magnification.  In this picture, I have focused on the inclusion so you can better see how its color allows it to blend in with the natural color of the diamond.

The next diamond I want to review is a 1.01 carat VS2.  As you can see in Figure 3, there is a very small inclusion almost dead center in the table of the diamond. Unfortunately, however, the inclusion is stark black.

Due to the combination of the inclusion’s position and its color, it is very possible it would be visible to the naked eye despite the fact that it has a clarity grade of VS2.

Figure 4: VS2 at 18x

Figure 4: VS2 at 18x

Comparing Inclusions

In Figure 4, you see the same inclusion, but at 18x magnification.

Now take a look at the table below (Figure 5) of the two different diamonds’ features.  They are virtually identical, save for three slight advantages the I1 has over the VS2 (No Fluorescence and Excellent polish, and slightly larger dimensions).

Now try to guess their prices. The VS2? Listed on JamesAllen.com for $5,010.

The I1, which as I have shown isn’t simply a better value for your money spent, but is objectively speaking a better looking diamond?  $3,290.

Don’t Invest in a Bad Decision

The VS2 costs over 50% more than the I1!  And you know what you get in return for that $1720 extra you spent on the VS2?  A little black dot to always remind you of what a bad decision you made.

Shape Weight Color Clarity Polish Symmetry Fluorescence Measurements
Round 1.00 H I1 EX VG None 6.38×6.45×3.97
Round 1.01 H VS2 VG VG Medium Blue 6.36×6.40×3.99

To wrap things up, recall the pie analogy I mentioned earlier.  Wouldn’t it make more sense to take keep the Clarity slice nice and small (like the I1 from Figures 1 and 2) and instead increase the size of the Weight slice?

In our example here, you could easily upgrade to a 1.25ct diamond and you would still end up spending less than $5,010.
