The clarity of a diamond refers to how clear, or "clean" the diamond is. The more "clean" the diamond, the higher the price. Most diamonds have "imperfections" in them. The clarity scale is a measure of the severity of those imperfections or "inclusions" as it is known in the trade.
For example, a deep break in a diamond which is not that visible when you look at the stone face-up, could sometimes have a greater impact on the clarity of a stone, than a small black crystal which you can see very clearly face-up.
The following is a Diamond clarity-scale:
These stones have no imperfections inside or on the outside of the stone under the magnification of a loupe of 10 power.
These stones have no inclusions under a loupe with a 10 power magnification.
VVS1,VVS2-Very Very Slightly Imperfect
These stones have very small inclusions which are very difficult to see under a loupe with a 10 power magnification.
VS1,VS2-Very Slightly Imperfect
These stones have small inclusions which are slightly difficult to difficult to see under a loupe with a 10 power magnification.
These stones have inclusions which are fairly easy to see under a loupe with a 10 power magnification, or visible to the naked eye.
These stones have inclusions which range from eye visible to very easily seen to the naked eye.
How much does "clarity" affect cost?
The effect of all the different properties of Diamond on Cost is discussed in more detail in the Cost section. For clarity, let's take a typical Diamond for an example, and see what happens when we take it through different clarity grades.
with a 1.00 carat Diamond of G color and SI1 Clarity. If you move
up to a VS1, you will pay approximately an extra $1000 per
carat. Move up to VVS1, the increase will be approximately
$700 per carat. Improve the clarity to IF and the
increase will be approximately $700 per carat.
