Clarity

The clarity of a diamond determines how captivating its gleam is. All diamonds have identifying characteristics, but most are invisible to the naked eye. Under the scrutiny of a jeweler's 10X magnifying loupe the appearance of tiny crystals, feathers or clouds can be identified. These natural phenomena are called inclusions. Large inclusions may interfere in the passage of light through a stone, resulting in low clarity. There are twelve clarity grades, ranging from internally and externally flawless (FL) down to I3 grade, which is heavily included with imperfections clearly visible to the naked eye.

FL & IF
Diamonds that reveal no flaws on the surface or internally. These are the rarest and most beautiful gems treasured for their absolute purity.

VVS1 or VVS2
Diamonds with minute inclusions absolutely invisible to the naked eye. Only through careful inspection with a microscope can these tiny inclusions be accurately pinpointed. The brilliance of the stone does not suffer in this category.

VS1 or VS2
Diamonds with tiny inclusions difficult to locate. Only a trained eye looking through a 10X loupe can pinpoint the inclusions in this category. The inclusions are nearly impossible to see with the naked eye.

SI1 - SI3
Diamonds with inclusions easily identified through a loupe. Finding flaws in this category with the naked eye is difficult for the SI1 - SI2 range. The gems in this category maintain their integrity, depending on the location of the inclusions. They are an attractive choice when working within a fixed budget without sacrificing beauty or value. Inclusions in an SI3 graded diamond may be seen to the unaided eye, although not with substantial ease. Consider an SI3 as a good I1.

I1 - I3
Diamonds with inclusions which may be seen by the naked eye. The flaws on the I2-I3 range in this category might have some effect on the brilliance of your diamond.
