   Do you mean VS1? There is no VI… unless they have created a new grade… “very included”… haha… which maybe they should.

   The scale is as follows:
   - FL (flawless) – no flaws at all
   - IF (internally flawless) – no internal flaws, barely visible blemishes on surface
   - VVS1 (very very slightly included) – very difficult to see inclusions even under 10x magnification
   - VVS2 (very very slightly included) – a little lower than VVS1
   - VS1 (very slightly included) – inclusions not typically visible to untrained eye
   - VS2 (very slightly included) – a little lower than VS1
   - SI1 (slightly included) – inclusions are visible under 10x magnification, and may be visible to the untrained eye
   - SI2 (slightly included) – a little lower than SI1
   - I1 (included) – often visible inclusions
   - I2 (included) – easily visible inclusions
   - I3 (included) – extremely visible inclusions

   It probably means V through I. That means from VVS1 (Very Very Small 1) through I3 (Inclusion 3)
