We're definitely going to take this outside when its sunny again to see how it looks in natural light. All the idealscope/ASET images point to this stone being great in light. We did also visit a jeweler that had a really brilliant diamond that we liked but my concern is it only looks great due to his special lighting. Without the ability to see ideal scope/ASET images for this GIA stone, how do you think it's light performance is (our biggest concern is light performance)? How do you think it compares to the WF ACA? I ran the proportions through the HCA and it did pretty good (I forget the exact number for it was somewhere near 1).
