While the Asscher is square in shape, it actually has eight sides but the four cropped corners aren't usually noticeable once mounted. What is the difference between an emerald cut and an Asscher cut diamond? Both emerald cut and Asscher cut diamonds are step cuts however an emerald cut has a wider more open table and the Asscher has a higher crown and smaller table making it the more brilliant of the two.
