I was shown a 1.06 diamond with excellent cut, D color, i1 clarity, faint fluorescence. The guy kept saying this is a beautiful stone and rare find for the price ($4350). I looked at it through a loop and saw one white feather at 5 o’clock, half of it on the table,, and I can notice it slightly when I look for it without the loup. Otherwise, the light bounces off and looks great. Is this a good deal? Or should I stay away from all I1s? Thanks.
