Clarity Grading: Sapphire clarity grades are assigned when a trained, experienced gemologist examines the gem "face-up" under controlled lighting without magnification. Sapphire clarity grades are assigned without magnification. Sapphire clarity grades are determined by an inclusion's visibility, or lack of visibility, to the naked eye. This is the procedure at the major Gem Labs. This is in sharp contrast to diamond grading where 10X magnification is required. The top sapphire clarity grade at American Gemological Laboratory is "Free of Inclusion" and the top sapphire clarity grade at Asian Institute of Gemological Sciences is "Flawless". According to the Gemological Institute of America's Revised Colored Stone Grading Lab Manual, the top clarity grade for sapphire is "Eye clean". These grades are assigned when an experienced, fully-trained gem-grader is unable to see any inclusions under ideal lighting conditions and without magnification. When examined under magnification, almost all sapphires show some natural inclusions, regardless of whether these inclusions are visible to the naked eye. So, a sapphire that is honestly graded "Flawless" or "Free of Inclusion" or "Eye-clean" almost certainly contains inclusions at some level of magnification. (As do most Flawless diamonds!) 10X is the basis for diamond clarity grading. Naked-eye is the basis for sapphire clarity grading. Diamonds and sapphires almost always show natural inclusions if the magnification is high enough. |

| Flawless | Lightly IncludedL | Moderately IncludedL | Highly IncludedL | Extremely IncludedL |
Flawless Sapphires show no inclusions to the unaided eye when examined by a trained, experienced grader using an ideal light source. Lightly Included 2 ( LI2) is similar but with one or two more inclusions, of the same minute size. LI1/LI2 inclusions are so small that most people cannot see them without magnification, even after intense scrutiny of the gem. Moderately Included 2 (MI2) inclusions have a slight effect on appearance but do not affect brilliance. These inclusions are often not visible to the casual observer. Inclusions in MI1/MI2 gems are so small that many people cannot see them without magnification.
Highly Included 1 (HI1) Inclusions are obvious and have a slight effect on appearance and brilliance. Highly Included 2 (HI2) Inclusions are obvious and have a significant effect on appearance and brilliance.
Extremely Included 1 (EI1) Inclusions are prominent with significant effect on appearance, brilliance and transparency. Extremely Included 2 (EI2) Inclusions are numerous and prominent throughout gem with severe effect on appearance, brilliance, transparency and durability. Extremely Included 3 (EI3) Inclusions are numerous and prominent throughout gem. Gem is not transparent and shows no brilliance. |
