As a matter of fact, the degree of optical precision that the diamond exhibits might be even more important. The following tutorials will teach you how to judge light performance in super ideal cut diamonds:

Are Super Ideal Cut Diamonds Worth It?

The ASET Scope images below show three "ideal cut diamonds" with varying degrees of Light Performance. The standard GIA Excellent cut diamond on the left is showing signs of light leakage under the table facet. While the entry level Hearts and Arrows diamond on the right shows traces of secondary brightness under the table facet.

Hearts & Arrows

The Black by Brian Gavin Hearts and Arrows diamond in the middle exhibits the most even distribution of light. To begin with, notice how the light is reflecting more evenly under the table facet. At the same time, the degree of hue and saturation is consistent throughout the entire facet structure.

This means that the diamond is reflecting light evenly because of the higher degree of optical precision. Which means that you will see sparkle which is even more vivid and intense along with higher light return.
