The quality analysis system is as follows:
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.
A superior quality diamond. Very, Very Slightly Included: Very difficult to see inclusions under 10x magnification.
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.
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.
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.
