In two places in its guidelines, the phrase "...corrected magnifier at 10-power, with adequate illumination, by a person skilled in gemstone grading..." is used.

The highest clarity grade is F - Flawless, or IF - Internally Flawless.
AAA clarity is not a recognized rating for diamonds. The standard clarity scale for diamonds ranges from Flawless (no inclusions) to Included (visible inclusions). AAA is not a term used in the diamond industry to describe clarity.
Gem-stone diamond clarity is documented by a certified gemologist -- with an 'important diamond', potentially more than one gemologist -- according to a scale.From Wikipedia:"Diamond clarity is a quality of diamonds relating to the existence and visual appearance of internal characteristics of a diamond called inclusions, and surface defects called blemishes. ... Inclusions may be crystals of a foreign material or another diamond crystal, or structural imperfections such as tiny cracks that can appear whitish or cloudy. The number, size, color, relative location, orientation, and visibility of inclusions can all affect the relative clarity of a diamond. A clarity grade is assigned based on the overall appearance of the stone under ten times magnification."You can read more, below.
In diamond grading, "J" clarity refers to diamonds that have noticeable inclusions when viewed under 10x magnification. These inclusions may affect the diamond's brilliance and transparency but might not be visible to the naked eye. J clarity diamonds are considered lower on the clarity scale, but they can still be a good choice for those looking to balance quality and budget.
VVS1 stands for "Very Very Slightly Included 1," which is a grade on the diamond clarity scale. Diamonds in this category have minute inclusions that are difficult to see even under 10x magnification, making them very high quality and highly valued.
Trained gemologists use a 10x magnification to identify diamond clarity. You can read more about how clarity is graded by understanding the flaws and how they occur, below.
The highest clarity grade is F - Flawless, or IF - Internally Flawless.
The clarity grade of a diamond is determined by the number, and visibility, of its natural inclusions. Diamond clarity is rated using a 10x loupe, as a standard.Inclusions exist inside a diamond, or on its surface, and may be present in various forms, which include:pinpoints (white dots)carbon (black dots)feathersbubblescrystalscracksscratcheschipsYou can read more about diamond clarity, below.
IMP1 Clarity refers to a diamond clarity grading scale used by some diamond sellers. It is typically considered to be an inclusion-heavy grade, indicating visible inclusions within the diamond that can affect its appearance and value. Diamonds with IMP1 Clarity may have noticeable flaws and imperfections when examined under magnification.
AAA clarity is not a recognized rating for diamonds. The standard clarity scale for diamonds ranges from Flawless (no inclusions) to Included (visible inclusions). AAA is not a term used in the diamond industry to describe clarity.
Clarity for a diamond describes the number and amount of flaws or inclusions in a stone. Perfect clarity -- the lack of any flaws or inclusions -- is called Flawless, or Internally Flawless, which is the highest clarity grade.
A rough rule-of-thumb magnification level is ten times normal vision, written as 10x. This is the general magnification standard for jewelery. Some diamond merchants, however, may use a stronger magnification by personal choice.
According to the Gemological Institute of America, from Wikipedia, below: "Included category (I) diamonds have obvious inclusions that are clearly visible to a trained grader under 10x magnification. Included diamonds have inclusions that are usually visible without magnification or have inclusions that threaten the durability of the stone." A gem rated with I-1 clarity indicates that a single inclusion is visible. This is the highest rating for the included category, which is the lowest rating for diamond clarity.

SI stands for "slightly included" and is a classification used to describe the clarity of a diamond. Diamonds with SI clarity have inclusions that are noticeable under 10x magnification but may be difficult to see with the naked eye. This clarity grade represents a good balance between quality and value for many buyers.
SI2 indicates that in at least two places inside the diamond, inclusions, however slight, are visible.You can view diamond clarity images, below, including one for a diamond graded as SI2.
