The classification of clarity:
Clarity is a measure of the number and size of the tiny imperfections that occur in almost all diamonds.
Many of these imperfections are microscopic, and do not affect a diamond's beauty in any discernible way.
Much is made of a diamond's clarity, but of the Four Cs, it is the easiest to understand, and, according to many experts, generally has the least impact on a diamond's appearance. Clarity simply refers to the tiny, natural imperfections that occur in all but the finest diamonds. Gemologists refer to these imperfections by a variety of technical names, including blemishes and inclusions, among others. Diamonds with the least and smallest imperfections receive the highest clarity grades. Because these imperfections tend to be microscopic, they do not generally affect a diamond's beauty in any discernible way.

Very Slightly Included: Imperfections are not typically visible to the unaided eye. Less expensive than the VVS1 or VVS2 grades.
Slightly Included: Imperfections are visible under 10x magnification, and may be visible with the unaided eye. A good diamond value.

What Clarity Grade Is Right For Me?
Select an "eye-clean" diamond - one that has no imperfections visible to the unaided-eye through the crown. An excellent value, diamonds of this clarity are much less expensive than flawless (FL) or internally flawless (IF) diamonds, which are extremely rare and command higher prices.
Frequently, imperfections in diamonds graded slightly included (SI) are not visible to the unaided eye, making them an excellent value. If you're considering a diamond with an SI clarity grade, call to speak to a diamond and jewelry consultant who will review the diamond to ensure the imperfections are not visible to the unaided eye.
