I''ve purchased this Diamond and am trying to decipher how good or bad these readings are. Should I be concerned that the cut quality readings are very good and not excellent?
Anyone familiar with the software please help.

It is just a matter of what names one assigns to numeric values.

In Diamond Calculator (or GemAdviser) performance of Tolkowsky cut stone is taken as 1.0 and called Very Good.

One also could call it Excellent or Ideal...

This diamond has LR and Leakage close to 1.

There are proportions though when light return will be >1 but those diamonds might have less contrast and fire (not implemented in DC yet).
