I have been looking into round GCAL 8x diamonds and have run into a question. When looking at a lower-quality round GCAL, how would that compare to an ideal round IGI diamond? Is there going to be a noticeable difference between the two? I have seen a decent amount of Ideal IGI I would potentially pull the trigger on, but I do not see a lot of GCAL within the size range (~7.5-7.6mm) that I am looking for. I am unsure if other people have run into this dilemma as well and if there is a clear choice.
