Pyramid,
and ultimately it doesn''t matter if 99% of butts look big in those jeans as long as YOUR butt looks fantastic!!
Thank you Sergey,
However, what the AGS, GIA and MSU charts and I have demonstrated and Sergey''s photorealistic imagery has backed up is not changed or negated under reductions in symmetry. Both these diamonds with identical beauty and optical performance will degrade in performance in a similar manner as symmetry is reduced.

Thanks michaelgem
Not getting into any technicals here because I don''t know about it, I do understand what you are all writing and what you all mean but I am a non knowing person regarding talking about any of it myself.
However the inverse crown and pavillion angles, I believe was something that Garry Holloway found out I believe long before GIA AND AGS and yet they are the people always quoted for it. I think they ought to stand up and attribute that to Garry, ha just speaking from a consumer point of view and I like to see the people get the praise for it in the same way Morse should if his diamond angles were better than Tolkowskys. Garry says in the tutorial that his finding this out was just ''common sense'' but I put that down to his Australian way of talking a bit like the British we don''t brag enough, but Garry it was not common sense because otherwise the diamond angles put up by AGS etc would have accounted for it and they didn''t in the past. So I do think Garry needs to be recognized for something which only he thinks is ''common sense'' because of his great mind.
I am not really talking myself out of it, but I am sort of piggy in the middle here when there are two very well read and practiced people with differing views, yourself and Brian the Cutter, not to mention other gemmologists and Garry''s (who is a gemmologist too) HCA measuring the diamond as lacking even if just a small amount in Fire and Scintillation from one which receives 4 EXs on his HCA although I know he has said himself the tool is for a first rejection and not to put too much into the 4 EXs part of it.
Pyramind thanks for the kudos, but HCA is a rejection tool - and you are using it as a grading tool on a diamond with excellent sym and perfect proportions.
So anyway, will GIA and AGS recognise Garry Holloway for the inversion thing which he told the public about before GIA and AGS even knew about it?
Older pre lab cutters ''box'' type cut grades knew about it too, and Peter Yantzer acknowledged it after I gave him a DiamCallc demo showing why a 25 degree crwon angled stone could be very beuatiful with a deep enough pavilion, but thx Pyramid.

re:that a point had not been proven that 34/41 was in general as good as 34.5/40.75 or 34.7/40.8
I can't answer for Paul but I think he is still on his side of the fence and the scientific people are still on their side. I think he just got a bit frustrated with it all. Maybe a Cutters way of proving it would be to produce two stones cut to prove their point whereas scientific is more to do with words. Maybe the Cutters can see something about the diamond that Scientific people cannot in the same way they would not maybe know your side.

Thanks Michaelgem, oh I have always realised that Sergey here is brainy and certainly something that most people could never obtain in their lifetime, I also know that you know a lot about the subject yourself as does Brian and all the Cutters. I am reading and appreciating and know that you are all getting something from this too, it is not just about one diamond, this one, but about Pricescope and the information that those who know about it can get from each other, and those consumers like myself can learn a bit about it, if we are interested, even though we will never know the intracies without education in the subject at a higher level and maybe even a level we could never obtain.
I have spent almost 10 years findiing ways to simplify for my ciients, folks like you, why the Super Ideal is the most beautiful and highest performing of round brillinat cut diamonds. A read of just these two articles, http://www.acagemlab.com/articles/sweetspot/index.html and http://www.acagemlab.com/articles/DiamondEye.htm , will get you to that higher level, which is well within your reach should you choose to grab it
I appreciate what everyone has written here, very very much, and that is from both sides of the fence. Maybe there is no right like many things in life.
Sorry, if anyone thinks there is no right to the issues and points discussed here, they have not studied the evidence well enough. If I were a judge talking to the jury, I would council them to go back and restudy the body of evidence presented, and don't return until you have reached a verdict.
Best wishes,
Michael
Not convenient at the moment. I am starting to think though that maybe the 34/41 is not so bad. I do think that cone thing I went on about was the smaller table because in the UK we are not used to seeing tables smaller than 57.5 or maybe it is 60s we see here, not sure, but it is smaller than my diamonds and any diamonds I have seen around on other people some who I know could afford very expensive and probably bought from highend places. The image Serg put up with 57.5 table looked more normal to me, so it is I believe just what I am used to seeing on people and in jewellers displays. I don't see any colour much at all in the diamond and has never bothered me as I said. I don't think I see any difference to do with under the table being darker to the stars and kite facets. There was beautiful fire and movement when I did see it in the sun for about 5 minutes so I think I just need to decide now what I want to do. If I was not getting this one I would not be going to USA anyway because I would have to look for another in this unusual weight which could take a while or save up more money to get 2 carat range if they are more plentiful in the H colour. I do not want to go below H so I am stuck there and I will not go below VS1 clarity. So I am still uncertain and just need a few days to make up my mind about keeping or returning the diamond. These conversations though between the experts I am finding interesting even if it was not to do with the diamond I am considering. As I have thought before there will always be another diamond and I have learned over 5 years here not to get too stuck on the one.
yea but if you use the charts that Serg has generated from the pgs software it moves right back.
I did mention that (highlighted). I think it can be demonstrated that neither chart has teeth... Do two naughties make a nightie?
