As Garry says, does the grading report have any comments? I had to return a cloudy/hazy Vs2 stone because I didnt know that the comment "clarity grade is based on clouds not shown" could affect transparency so much. The stone I returned also had a remarkedly clean inclusion plot and looked super clean in magnified video.
EDIT: Since this is below 1 carat and wont have a clarity plot, is the main clarity characteristic cloud?
