Please help find the best performer between these 3 options

[funketrade]

Since there are various ways of judging stone performance ie HCA score, AG0 / GIA3x status, vendor-specific 'premium' lines, I would really appreciate if you could suggest which of these 3 'premium branded' stones I can expect the best performance since cut quality is my priority (ignore differences in colour and clarity). I also added a 4th stone for size/cost but since it's not in-house and has no 'premium branding' I'm not really leaning toward it :

On a related note - is there any risk of putting a stone with Thin to Medium girdle in a bezel setting?

Thanks for ALL your help!!

Re: Please help find the best performer between these 3 opti

If you can get idealscope of the JA stones and gemologist review, that would help. All the others are going to have idealscopes already. Then a more fair comparison can be made.

I think that a bezel setting is the best protection for any girdle (thin, medium, or otherwise) so I don't think that you should have a problem there.
