My AG came today and I was SO excited to see it, but I have to admit I am a bit disappointed. The rainbow flashes look just like my fb moissanite, possibly even more so. I thought this stone was more diamond like in behavior? In all the videos I've seen they look really sparkly and bright but mine is REALLY rainbow-y (made up word, but you know what I mean, ha!) I got a I color, could that be why? Would a higher color grade sparkle differently? I just didn't want it to be too white.
