this actual clarity grading chart shown by microscope and by importance of flaws

GIA defined and Identified by different blemishes on images magnified X 100 by microscope.

Recognize the visual impact and influence of spots on prices on polished diamonds.
View types of inclusions classified by categories of importance of impurities:

Grade and evaluate diamond clarity by real photographs to identify visual internal and external inclusions and blemishes.

Diamond clarity grading is an opinion, not a mathematic scientific fact!
Inclusions are crystals or structural imperfections such as whitish clouds, cracks, feathers, knots and black spots.

The quantity, size, color, location, orientation and visibility of inclusions can affect the clarity by SI3 and piqué.

Most inclusions in diamonds do not affect the brilliance.
Diamonds with highest clarity grades are more expensive, because much more rare.

Clarity grading by images, photo's made by microscope.

Diamond grading chart

GIA Diamond Grading
Laboratories uses a microscope to measure the importance of the spots in microns.

The following clarity grades are called Loupe Clean, Cleanish and Piqué,
determined by the size, position, brightness and quantity of internal and external inclusions / flaws / spots on scale.

LC / IF – a diamond is called Loupe Clean and Internally Flawless when no internal spots are visible magnifying x 10 – Loupe Clean.

VVS1 – Diamond with Very Very Small inclusions / spots 1st degree. Extremely difficult to detect even by experienced grader with a loupe magnifying x 10 Loupe Clean.

VVS2 – Diamond with Very Very Small inclusions and spots of 2nd degree. Extremely difficult to detect even by experienced grader with a loupe magnifying x 10 Loupe Clean.

VS1 – Diamond with Very Small inclusions / flaws / spots 1st degree. Difficult to detect even by experienced grader with a loupe magnifying x 10 Loupe Clean.

VS2 – Diamond with Very Small inclusions / flaws / spots 2nd degree. Difficult to detect even by experienced grader with a loupe magnifying x 10 Loupe Clean.

SI1 – Diamond with Small Inclusions / flaws / spots 1st degree. Eye Clean. Detectable with a loupe magnifying x 10

SI2 / SI3 – Diamond with Small Inclusions / flaws / spots 2nd degree and 3 nth degree. Detectable by nacked eye

I1 / P1 – Diamond with Inclusions, flaws / spots 1st degree. Visible by nacked eye, spots / flaws Detectable by naked eye. Also named Pique 1

I2 / P2 – Diamond with Inclusions : flaws / spots 2nd degree. Visible by naked eye. Also named Pique 2

I3 / P3 – Diamond with Inclusions / flaws 3rd degree. Obvious inclusions, / spots easily visible by naked eye affecting transparency and brightness. Also named Piqué 3
