Diamond Clarity

Anything with flawless beauty is rare indeed. But it’s actually slight imperfections that make beauty unique. And so it is with diamonds. Diamond clarity refers to the assessment of imperfections of a stone. Nearly every diamond has external and internal characteristics that we call blemishes and inclusions. Blemishes are surface marks and inclusions are imperfections within the stone.

Diamonds are formed underground, under tremendous heat and pressure, making it extremely rare to find a 100% perfect diamond. While the rarest diamonds are almost flawless, most have some form of blemish or inclusion, but this adds to their uniqueness – no two are exactly alike.



It is estimated that less that 1% of diamonds in the entire world have a Flawless Clarity.


Diamonds with no or few inclusions are significantly higher in value than those with less clarity and will receive a higher quality grade. While inclusions affect the value of a diamond, the beauty is rarely affected, as in most cases these small imperfections cannot be seen by the naked eye.


Flawless diamonds show no inclusions (internal imperfections) or blemishes (external imperfections) of any kind when examined under 10x magnification by a skilled grader.


Internally flawless diamonds show no inclusions when examined under 10x magnification by a skilled grader. They do, however, have some minor blemishes.


The VVS category has 2 grades – VVS1 and VVS2 (VVS1 denotes a higher clarity grade than VVS2).

VVS1 diamonds contain minute inclusions that are difficult for even experienced graders to see under 10x magnification. VVS2 are also very difficult to see and might include tiny cavities or pinpoints.


The VS category has 2 grades; VS1 and VS2 (VS1 denotes a higher clarity grade than VS2).

VS Diamonds contain small minor inclusions than can be observed (with effort) under 10x magnification.


The SI category contains 2 grades; SI1 and SI2 (SI1 denotes a higher clarity grade than SI2).

SI Diamonds contain inclusions that are noticeable to an experienced grader under 10x magnification. These inclusions may or may not be noticeable to the naked eye.


The I category contains three grades; I1, I2 and I3.

I Diamonds contain inclusions that are obvious under 10x magnification and usually visible to the naked eye. Diamonds that fall into this category tend to be less popular as they often lack transparency and durability.

buying tips


Remember the 4Cs (carat, clarity, cut and colour)? We think a good balance of the 4C’s is better than solely focusing on one aspect of the diamond. Diamonds with a higher clarity are much rarer and therefore very valuable. However, as mentioned above, many inclusions and blemishes cannot be seen by the naked eye. We often advise our customers to spend greater budget on a better cut or colour, rather than trying to get a 100% flawless diamond.

The most common diamond clarity is SI1 (see the grades, above). These diamonds provide a happy balance between clarity and price. For the majority of us, an SI1 diamond will look perfect. However, if you have a high budget, then a rare higher clarity diamond is a good investment, as it will be of a very high value.


The most common diamond clarity is SI1. S1 diamonds provide a good balance between clarity and price. However, higher clarity diamonds are much rarer and therefore, more valuable.
