It is my thought that just considering the table and depth and making a conclusions about how good or poor a cut is certainly not much information to make a determination.
I started writing about the importance of the other 40 facets years ago. Even on the AGS reports, the crown measurement average and the pavilion average were just not enough.
So just as some feel that it''s improper that a 60/60 is good or beautiful - it is just as improper to say a 55 / 60 is the "best ideal".
It appears the labs are finally waking up to this and to light return analysis considerations, and that is good, but we ain''t totally there yet.
There are just a lot of very complex other characteristics that can affect the appearance of a diamond. I think we all sort of are in agreement that the eye''s are still the best, but that too requires the trained eye to be able to notice what succint differences enhance the appearance. The improving techonology is a great teacher in many aspects, even for expert eyes, and as time goes on it will get even better.
At the moment there is too much prediction type analysis and not enough attention is being made into visual, actual performance analysis - but it is coming, and in part arrived in some of the various items of equipment that has the ability to discern things that our eyes sometimes miss. Again, the eyes are still the boss, but it doesn''t hurt to have advanced technology back up to support the human conclusions.
I agree a lot is personal preference, but many time the "decision" of which preferences is made from a very "untrained" circumstance, particularly with consumers, as many tend to believe what the sales person says as gospel.
