This is a new ring. I have just upgraded from a 1.64 round ring to this 3.54 radiant cut. I am now unsure about this stone and have only two weeks to return it for something else. It is E colour si1. The thing is I am not sure about is the cut. It is cut very deep and looks more like a 3 ct.It is 9mmx8mmx? I am thinking maybe I would have liked the look of a 3ct round or cushion better. I would love to hear what some of you think.
