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


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


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


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

VVS1 or VVS2.
