A reflector is the result of the inclusion’s

position

Blemishes don’t usually affect the clarity grade in diamonds below

IF

The more an inclusion differs in color from its host diamond,

the more obvious it is.

A feather that reaches a bezel surface as well as the surface of the pavilion main directly under that bezel

should be plotted on both the crown and pavilion diagrams.

A stone with only a few extra facets on its pavilion that can’t be seen face-up should be graded

IF

VS1 and VS2 stones would be expected to have


minor included crystals and feathers

One factor used to determine the clarity grade of a diamond is an inclusion’s

location

In a stone with these clarity characteristics, which would probably be the grade-setting characteristic?

Feather

Diamonds with minute inclusions that are difficult for even a skilled grader to see under 10X are classified

VVS1 or VVS2.

Inclusions are usually most visible when they’re located

directly under the table.

A round brilliant-cut VVS diamond could have

a small pinpoint under a lower girdle facet.

The designation SI means

Slightly Included.

Which of these would disqualify a stone from being graded IF?

Pinpoint

On a plot, drawing a characteristic only in green indicates that it’s

a blemish

In most cases, the easier it is to see a clarity characteristic, the

lower the clarity grade.
