A diamond's clarity is affected by any detectable external irregularities and internal
imperfections created by nature when the diamond was formed.
Imperfections such
as spots or lines are called inclusions. The less inclusions, the higher the clarity
and thus, the greater brilliance and ultimately, value.
Inclusions can interfere with the passage of light through the stone, diminishing
the sparkle and value of the diamond.
According to the quality analysis system of
the Gemological Institute of America, clarity is graded on a scale ranging from
internally flawless (IF) to included (I).
To be graded flawless, a diamond must
have no inclusions visible to a trained eye under a 10x magnification in good light.

The quality analysis system is as follows: |
|
FL, IF Diamonds:
|
|
These diamonds are the most rare and most expensive. These diamonds have been graded
as (FL) Flawless: no internal or external flaws. (IF) Internally Flawless: No internal
flaws.
|
|
|
|
VVS1, VVS2 Diamonds:
|
|
A superior quality diamond. Very, Very Slightly Included: Very difficult to see
inclusions under 10x magnification.
|
|
|
|
VS1, VS2 Diamonds:
|
|
A lesser quality than the VVS1 or VVS2 grades. Very Slightly Included: Inclusions
are not typically visible to the unaided eye, but are viewable at 10x magnification. |
|
|
|
SI1, SI2 Diamonds:
|
|
When combined with other factors, these grades represent good value. Slightly
Included: Inclusions are visible under 10x magnification, and may be visible with
the unaided eye. |
|
|
|
I1, I2, I3 Diamonds: |
|
These diamonds contain inclusions that are visible to the naked eye. I grade diamonds
are often purchased by customers seeking the largest stone possible for their money
and these individuals are therefore not concerned about inclusions. However,
K E Butler and Company Jewelers does not offer I2 or I3 grade diamonds. |
