What Clarity Grade Should I
Apart from their shape, diamonds can be differentiated by taking a look at their major
characteristics, also known as the "four C's" of diamonds: cut, carat, color and clarity. Out of these four, clarity is the one that one needs to
examine in order to determine the value of a piece of diamond.
Almost every solid material has a number of imperfections inside them; clarity is a measure of these. The more
imperfections you can find in a diamond, the lower its quality and price will become.
You should not think that a diamond with 3 minor imperfections is worthless or won't be beautiful to the eyes.
The truth is, a very high number of dislocations (that is the scientific term for these imperfections) are needed
to be there until you can observe any problem with your bare eyes.
What Will Guide Me When it Comes Identifying Different Clarity
There are international standards that help us define the quality of a given diamond. According to these
standards, the clarity of diamonds can be classified into one of the following categories (from best to worst
- FL (Flawless), IF (Internally
Flawless) - these are practically perfect diamonds, with no microscopically observable
flaws. These are extremely rare stones, and if you were about to buy one of these you probably would have
talked about the acquisition on your yacht with one of your aristocrat friends.
- VVS1 and VVS2 - Very, very slightly included - These diamonds are also
quite rare. They have so subtle imperfections that they can only be observable under microscope. Very high
price tag, in exchange for superb quality.
- VS1 and VS2 - Very Slightly Included - An amateur eye probably
will not notice the imperfections in diamonds classified in these categories. These stones can make an
excellent purchase for the majority of diamond buyers.
- SI1 and SI2 - Slightly included - These diamonds have
imperfections that most people could notice. However, the increase of flaws comes with a decrease of price,
so some people might want to consider one of these diamonds.
- I1, I2 and I3 - Included - The problems
in these diamonds are obvious to the naked eye. Such stones are usually used for industrial purposes; in my
opinion, they are not a good fit for jewelry.
How Should I Interpret all These Different Classes?
These categories are not too hard to learn and knowledge of them might come in handy. However,
when it comes to actually buying a diamond the situation is usually even simpler. The FL, IL and VVS
categories are so rare that you will probably not see much in store windows.
Also, diamonds classified as I1, I2 or I3 are of so low quality that most jewelers will not allow them into
their businesses; they would only lower the reputation of the store. Often, when you see jewelry stores selling
diamonds at ridiculously low prices - (1 carat for $2000), chances are, these are the kind of diamonds that fall in
I1 - I3 ranges.
So, What Clarity Grading Should I Choose, After All?
Most diamond buyers will probably want to choose diamonds from the VS1 and VS2 categories. Also, if your budget
is tighter, choosing slightly included diamonds is still a viable option. To put your money to its best value, I
would recommend you to purchase diamonds within the range of VS1 - SI2 that are
The rest of the categories appear at the extreme ends: you will probably only find internal flawless diamonds in
royal jewelry and you should only use very included diamonds to cut glass or other, more beautiful diamonds.
