The GIA Clarity Scale includes eleven clarity grades ranging form Flawless to I3. Because diamonds form under tremendous heat and pressure, it is extremely rare to find a diamond that lacks any internal and external characteristics. These characteristics are a by-product of its formation and help gemologists and jewelers separate natural diamonds from synthetics and simulants, and identify individual stones.

IF - Internally Flawless Has no inclusions when examined by an experienced grader using 10X magnification, but will have some minor blemishes.
VVS1 and VVS2 - Very, Very Slightly Included Contains minute inclusions that are difficult even for experienced graders to under 10X magnification.
VS1 and VS2 - Very Slightly Included Contains minute inclusions such as small crystals, clouds or feathers when observed with effort under 10X magnification.
SI1 and SI2 - Slightly Included Contains inclusions (clouds, included crystals, knots, cavities and feathers) that are noticeable to an experienced grader under 10X magnification.
I1, I2 and I3 - Included Contains inclusions (possible large feathers or large included crystals) that are obvious under 10X magnification and may affect transparency and brilliance.
