GIA - Report Check

The inclusions listed on the clarity plot should be eye clean and clear to the naked eye.
As advised above: get videos.
Also, request IS and ASET images of the stone so you can see if any obstruction occurs in the performance grid.
All of these visual aids will help to assist you in evaluating an SI graded stone, without the ability to examine it up close and personal with your naked eye.
As advised above: place the stone on HOLD.
