This stone is not an emerald cut diamond. It’s a criss cut or tycoon cut.
Did the jeweler explain to you the difference?
Yes, I think that this is really important. Personally I like that style of cut, but if she wants an emerald cut it's not that.
I say that is someone that would be interested in owning one one day as a fun stone, but I already own an emerald cut diamond that I am happy with.
