Selecting a diamond ... Diamond clarity

Selecting a diamond ... Diamond clarity

The clarity of a diamond is determined by the number and size of interior characteristics called inclusions and exterior characteristics called blemishes. They can interfere with the passage of light through the stone, diminishing the sparkle and value of the diamond. Both inclusions and blemishes occur naturally in diamonds. The Federal Trade Commission has established standards of measuring clarity with 10 powered magnification.

At Barmakian Jewelers we follow that standard and detailed system of guidelines to show the number, location, size and type of inclusion present in a diamond.


Clarity Chart
VVS1 -
VS1 -VS2
SI1 - SI2
I1 - I3
Very, Very Small
Very Small Inclusions
Small Inclusions

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 and SI3 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, our website does not offer  I3 grade diamonds.
