The overall proportions are what drive the light return of a diamond, in particular the crown and pavilion angles, but it is everything working together which results in a beautiful diamond. Symmetry and polish are the details of finish and usually with a top cut diamond both symmetry and polish are of very high standards as a by product of the craftmanship and attention to detail.

It is the cut quality. Of course, it is our eyes that perceive that brightness and fire, and our tastes that that perceive whether or not we like a given cut.

If you continue searching, you will find many answers to your question, some heavy discussions and more than a few strenuous disaggreements about which answer is correct, but the short answer is that it is the cut quality.
