Clarity grades define the quantity, size, and location of inclusions in a diamond examined under 10x magnification.
White inclusions are more desirable than black carbon inclusions.
Inclusions located in the center of a diamond impact value more significantly than those located towards the outside edge [girdle].
Described below is the diamond clarity grading scale:
Flawless: No surface blemish or internal inclusions present at all.
Internally Flawless: Indicates a microscopic surface blemish.
VVS1 and VVS2: Very, very slight inclusions:VVS grades indicate inclusions that are barely visible even under 10x magnification – a single microscopic pinpoint.
VS1 and VS2: Very slight inclusions:Relatively insignificant inclusions – visible only under 10x magnification.
SI1 and SI2: Slightly included:Inclusions more easily detectable under 10x magnification, however not visible to the naked eye.
I1, I2 and I3: Heavy inclusions easily visible to the naked eye in varying degrees.
