Question: is 2 carat moissanite too big?
Answer: Dakota2: Forever brilliant is enhanced and a 2 carat moissanite will be slightly bigger than a 2 carat diamond. I think for a size 7 finger, 2 carats wouldn't seem to big at all. Plus, you'll want to account for shrinkage (once you get used to the ring on your finger, it looks smaller than it is).
