Clarity Scale

The clarity of a diamond refers to the prominence of tiny imperfections found within the diamond. A diamond with very small imperfections, also known as inclusions, is not uncommon, as many can only be seen with a magnifier and the fewer of them there are, the more rare and expensive a diamond becomes. There are 11 grades of clarity and these reference the visibility of the inclusions. The overarching grade categories are: FL (flawless), IF (internally flawless), VVS (very, very small inclusions), VS (very small inclusions), SI (small inclusions), and I (imperfect). While an inclusion occurs on the interior of a diamond, a blemish occurs on the exterior of a diamond, and both of these are considered when assessing clarity.
