NOTE: The following do not disqualify a diamond from the Flawless grade: An extra facet on the pavilion which cannot be seen face up; Naturals totally confined to the girdle, which neither thicken the girdle nor distort its outline; Internal graining which is not reflective, white or coloured and does not significantly affect transparency.

Internally Flawless (IF): IF diamonds shall be free from internal characteristics / inclusions and shall only possess external characteristics / blemishes when examined under 10 x magnification. NOTE: The following does not disqualify a diamond from the Internally Flawless grade: Internal graining which is not reflective, white or coloured and does not significantly affect transparency.

Very Very Slightly Included/Very Very Small Inclusions (VVS): VVS diamonds shall contain minute internal characteristics/inclusions when examined under 10 x magnification. VVS1 diamonds shall contain minute internal characteristics/inclusions which shall be extremely difficult to observe when examined under 10 x magnification. VVS2 diamonds shall contain minute internal characteristics/inclusions which shall be very difficult to observe when examined under 10 x magnification.

Very Slightly Included/Very Small Inclusions (VS): VS diamonds shall contain minor internal characteristics/inclusions when examined under 10 x magnification. VS1 diamonds shall contain minor internal characteristics/inclusions which shall be difficult to observe when examined under 10 x magnification. VS2 diamonds shall contain minor internal characteristics/inclusions which shall be somewhat easy to observe when examined under 10 x magnification.

Slightly Included/Small Inclusions (SI): SI diamonds shall contain noticeable internal characteristics/inclusions when examined under 10 x magnification. SI1 diamonds shall contain noticeable internal characteristics/inclusions which shall be easy to observe when examined under 10 x magnification. SI2 diamonds shall contain noticeable internal characteristics/inclusions which shall be very easy to observe when examined under 10 x magnification.

Pique 1 (P1): P1 diamonds shall contain internal characteristics/inclusions which are prominent when examined under 10 x magnification. They shall also be visible face up to the naked eye. NOTE: Under certain circumstances, internal characteristics / inclusions may also be visible face up to the naked eye in higher grades.
