No Surprises --> Check my Logic, Please

[EuroYank]

Hello Everyone,

Being a Project Manager, I hate surprises on a project like choosing an e-ring. Please help me with my logic.

I am looking strongly at WhiteFlash because of their service and I have already been in contact.

Perhaps starting backwards, I am looking at the setting first to determine my budget for a diamond: Vatche platinum U-113 with semi-custom rounded shank for a 6.5 finger.

Basics
diamond budget about $10k
>1.2 cts.
cut = ideal, WF ACA or perhaps Expert Selection
> I color
> SI 1, eyeclean

Considering....
#1
1.342ct, "I" VS2, ACA

#2
1.317ct, "H" SI2, EShttp://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-3260762.htm

#3
1.30ct, "I" VS2, ACAhttp://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-3273930.htm

I just need a few comments so that I can make a final decision. I would very much appropriate your input.

After months of lurking on PriceScope, I have learned much about diamonds but also what a great community of experts are here. Thanks so much in advance.
All the Best,
Dan
