    It’s really impossible to say without the specs for each diamond and what you value as the most important “c”.

    The second from the top and the bottom one *appear* to be the best performers in the video, but take that with a grain of salt since it is impossible to make a good decision without the lab reports.  The specs of the cut are important, as are the inclusions and locations of inclusions, etc. (especially in lower clarities).

    @lawruh:  Which lab graded them as excellent? Excellent means different things to different labs.  AGS has the tightest parameters with their “ideal” cut.  GIA’s “excellent” is more liberal and many of their “excellent” cuts aren’t really that great.  For example, most agree that diamonds with a table percentage larger than their depth percentage should be avoided as they generally don’t perform as well; however, those specs can fall within GIA’s “excellent” cut.  All other lab’s parameters for “excellent” are much more broad.  Personally I wouldn’t chose any of them without reviewing the lab reports for the specs of the cut (not just the cut grade) and the types and locations of inclusions.

    @lawruh:  GIA is the most well known and is generally regarded as having consistent grading for the 4 C’s, but their highest cut grade of “excellent” includes a wider range of specs vs AGS’s highest cut grade of “ideal”.  That’s not to say you can’t get a GIA graded diamond within AGS’s ideal range, you just need to know what to look for in the cut specs.  And while AGS has a tighter “ideal” cut range, they have a reputation for being slightly lax in color grading (meaning an AGS H might be graded as an I by GIA).  Of course, this is assuming these are mined diamonds and not lab grown since AGS does not grade lab diamonds and most land diamonds are not sent to GIA.  IGI and GCAL are the best labs for grading lab created diamonds, but agin their parameters are known to be looser than GIA or AGS.  If you want in depth feedback on these diamond, post copies of the reports and up close pics and videos if available on the Rocky Talk forum at pricescope.com .  Good luck!
