I know some diamonds (especially fancy shapes) can appear larger than rounds. How does a cushion cut versus round cut appear? With the same carat size, would the cushion face up larger looking? Also, what about brilliance and fire? Obviously, nothing is like a well cut round, but is the cushion pretty good.....all things being equal? What kind of fancy cut diamonds appear very sparkly and larger? I have seen the pear....did not apeal to me, even though appeared bigger. Any input appreciated.
