Out of these 3 round diamonds? Blue Fluorescense concern?

[msdesign_enthusiast]

Hey all,

I wanted to get some opinions because after hours of researching and scouring online retailers with images, I think I've almost got it! I would really appreciate some additional guidance to make sure I'm not missing something.

Getting a custom setting - wrap around setting with halo, no prongs.

Debating between these 3 diamonds. I'm concerned about the fluorescense and color from different grader. I've read that an H color with AGS might not be an H with GIA?

In terms of cut, if GIA never rates Ideal, can I assume an excellent GIA is as good as an AIG Ideal or is an AIG ideal always better?

All 3 diamonds are VS2, round. They are less than $150 difference in price difference. They are all about the $7500 park from online company, JA (60 day return) Thoughts? Which is better of the 3? Is there something I am overlooking in all of them that I need to consider.

1.) AGS - 1.09 Carat - H - Ideal - depth: 60.9; width 56.9 - Polish/Sym: Ideal/Ideal
Fluor - None; Girdle: thin-Slightly thick; Cutlet: pointed

2.) GIA - 1.10 - H - Excellent - depth: 60.1; width 60.0 - Polish/Sym - Excellent, Excellent

Fluor - None; Girdle: Medium- Medium; Cutlet: none

3.) GIA - 1.14 - G - Excellent - depth: 59.6; width 60.0 - Polish/Sym - Excellent, Excellent ; Fluor - Strong Blue; girdle: medium-medium; cutlet - none


What would you get? Why?

My better half has a 4.5 finger and with the halo, I'm thinking a 1 carat or slightly bigger, 1.1 would be the right size and not too gaudy looking.

Thank you so much!!!!

Re: Out of these 3 round diamonds? Blue Fluorescense concer

Need more info. Crown and pavillion angles so you can run it through the HCA, for starters. You need light performance images (idealscope) - GIA X isn't good enough (it's too broad). Stick w AGS 0 if you are concerned.

And no it has not been proven that GIA grades color any differently than AGS. The best cut stones tend to go to AGS because they grade more strictly on cut quality - an AGS 0 rating is worthwhile. Stones that may not make AGS 0 often go to GIA bc they may get an excellent from them.

Either AGS or GIA is fine. But you need more info first.

ETA: read this https://www.pricescope.com/wiki/diamonds/60-60-proportioned-diamond Some of your stones are 60/60's

And SBF isn't a deal breaker at all. It's a very cool effect that is desired by many people, as long as it doesn't exhibit any milkiness / oiliness in UV light (sunlight) (It's very rare to see that anyway).
