Could anyone have a look at this diamond? What I have learned is the table % between 55-57% is best, but this one is 57.4%. The HCA score is 1.6. Also, what do the IS/ASET images tell? Thanks!!!

Its a beautiful diamond and the table size is fine.

IS and ASET images show light leakage or lack of and light return respectively, this link explains further

Thank you Lorelei! Does IS/ASET images in this diamond show any light leakage or lack of light return? I saw some white, which means leakage, in the IS image but not sure with it.

Most welcome! The white in the IS image which shows as evenly spaced little white triangular shapes towards the edge is controlled leakage which can aid contrast and scintillation in the diamond, so that can be beneficial to visual performance. Both images are excellent, no detrimental leakage in the IS image and the ASET looks good too.

The numbers on SARIN report are slighly different from those on AGS certificate. The table % per SARIN is 57.6%. Which one is more accurate?

No a problem, common to have some difference between sarin scan and lab report, AGS number should be the more accurate.

AGS numbers are the ones of authority, it is normal for some variance between those and that of a Sarin.
