Sometimes I think GIA does not know the difference between green and blue.
I mean, I see blue in this stone, as opposed to GIA, who saw green.
As with so many other things, my opinion does not count :)
In any event, here's a super cool blue...I mean green diamond. The color is natural.
The stone is nicely cut.
Sure, it's kinda small, but that does not take away from its lovely essence.
GIA color origin report - they don't offer full reports on stones of this size in the NYC lab.
