In truth, because each oval is unique, assigning a 'light return' grade to it is quite difficult. The light-return profile of long and slender ovals must be substantially different from that of a short and spherical oval. Labs may be able to determine the light performance of a diamond based on its dimensions by introducing the length to width ratio as a new factor to consider. Until then, comparing the brilliance of oval shape diamonds based on dimensions remains tricky, and the best way to judge cut is to examine numerous diamonds and choose the one that looks best to you.
