Diamond Clarity
Clarity ratings are determined by the number of inclusions (tiny pinpoints, markings, clouding, etc.) and how visible they are. Diamonds with fewer inclusions have better clarity, which increases their brilliance and value. Diamonds with clarity grades of FL and IF contain no internal inclusions that are visible under 10x magnification.
Diamonds with clarity grades VVS1 through SI2 have inclusions that are visible to varying degrees under 10x magnification, but should not generally be visible to the unaided eye.
Diamonds with I1 clarity contain inclusions that are easily seen under 10x magnification and may be visible with the unaided eye. Diamonds with I2 and I3 clarities have major inclusions that are easily seen with the unaided eye.
FL-IF
Flawless, Internally Flawless. A clarity grade of FL means that no inclusions or surface blemishes can be seen under 10x magnification. A diamond with a clarity grade of IF has no inclusions that are visible under 10x magnification, but it may have very small blemishes or polish marks on its surface. Diamonds with a clarity grade of FL or IF are extremely rare.
