Grading Scale

GIA Clarity Grading Scale


Flawless, internally flawless. No flaws internally or externally. Extremely rare and beautiful diamonds.


Very, very slightly included. Very hard to see inclusions under 10X magnification. Diamonds of excellent quality.


Very slightly included. Inclusions usually not visible to the naked eye. Cheaper than VVS1 or VVS2 grade loose diamonds.


Slightly included. Inclusions visible under 10X magnification and might be visible with the naked eye. Good value.


Included inclusions maybe visible without magnification, but an excellent choice for earrings. An SI3-I1 grade can be an excellent value, particularly since the inclusions are hard to see.


Inclusions can be seen without magnification and obvious under 10X magnification. May affect transparency and brilliance.
