Diamond for a halo bezel pendant (Down to 3 choices)

[NT]

Hello, I am in the process of choosing a centre diamond for this halo bezel pendant from whiteflash:
http://www.whiteflash.com/diamond-pendants/halo-bezel-diamond-pendant-279.htm

I have narrowed it down to these 3 diamonds (all .7-.75 carats and cost roughly the same), but now I am totally LOST, can someone please help me by looking at the Idealscope and ASET images to tell me which one would look best in the pendant.

Here is the link to the 3 diamonds in question:

Which one of these 3 diamonds would you guys choose? Please give your opinions.

those diamonds all look great. I doubt you could tell them apart, so I would probably pick the least expensive one.

ditto - flip a coin! Or choose the cheapest, from the info we have there's nothing about any of them that marks one as objectively "better" than the others. Once set you won't see the size difference btwn those three, colour is obviously up to your preference!
