It’s a pretty stone! I know nothing about cushions but if your preference is for the more ‘organised’ Style of light then this one looks beautiful. I think folks are waiting to hear your style preference; ie rounded, elongated, crushed ice or organised facet.
The stone seems nice, nice facets. Ideally, you would see an ASET, but you can buy one for $50 and examine it once you get the stone. Is the stone returnable? And what is the final price for that one?
We are assuming that the above is a round, the numbers are great. I think that it will be nice for you to compare the two diamonds. Cushions and Rounds are different shapes. I had a cushion and then moved to a round, but you need to ensure that your intended will love either of the shapes and that she doesn't have a strong preference for one but not the other
