Clarity Rating




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.




VVS1-VVS2 Very, Very Slightly Included. Diamonds with a VVS1 orAdd Image VVS2 clarity grade have tiny inclusions that are very difficult to see under 10x magnification. Diamonds with a clarity grade of VVS1 or VVS2 are very rare.




VS1-VS2 Very Slightly Included. Diamonds with a VS1 or VS2 clarity grade have small inclusions, such as pinpoints, included crystals, and feathers, that are visible with some difficulty under 10x magnification. Diamonds with this grade offer beautiful clarity at a lower cost than VVS or IF diamonds.


SI1-SI2 Slightly Included. Diamonds with a SI1 or SI2 clarity grade have small inclusions, such as pinpoints, included crystals, knots, clouds, and feathers, that can be seen somewhat easily under 10x magnification. It should be difficult to see any internal inclusions with the unaided eye. Diamonds with this grade should cost less than diamonds with a VS or VVS rating.


I3 Included to the third degree. Diamonds with an I3 clarity grade have major inclusions that are easily seen with the unaided eye. Diamonds with this clarity grade can have inclusions that are numerous and significant enough to affect the transparency and brilliance of the diamond. Amazon.com does not sell diamonds with I3 clarity.


I1-I2 Included to the first and second degree. Diamonds with an I1 clarity grade have inclusions that are numerous or large enough to be seen very easily under 10x magnification and may even be visible to the unaided eye if the location of the inclusion is known to the viewer. I1 clarity diamonds generally cost much less than diamonds with an SI clarity grade. Diamonds with an I2 clarity grade have very numerous or very large inclusions that are easy to see with the unaided eye, and cost much less than higher clarity grades.


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 (Internally Flawless) 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.
