I have a picture of a daniel k ring i tried on at pearlmans. it has a 1.5 cushion and although the ring itself is big, i wear a 3.5 so you can see what the size of the stone will look like. that said, the cushion only was a little over 6.5mm which is the same size as a 1 carat round, so definitely not too big at all. the stone also looks much bigger in this picture than it did in person.
