help with WF ACA Purchase

[navicular]

I currently have a budget of around 20k for a WF ACA loose diamond.
ideally I would like between a 1.3-1.8 carat diamond. D-G colour. vs1 or above.

What are your thoughts on G ACA vs F ideal stone? I originally wanted a colorless diamond but am considering size also. G will get me a bigger diamond, but i am not sure how it would look in terms of color?

So far I am looking at these 3 between 1.5-1.65.

I'm more color sensitive than most, I'd opt for the D. My next choice would be http://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-3051871.htm,, and that's what I'd recommend for most people.

I prefer size. h is as low as I go color wise. That diamond Andelin picked is my favorite too.

I would certainly go down to a G or H to get more size. Have you been to a store and looked at GIA/AGS0 colored stones to
see what you would be happy with.

Dont compare them side by side. Look at the lower colors first (G/H) and decide if they will work. If not, work your way up the ladder
to F, E, D colored stones until you find a color that you are happy with. In well cut (ideal/excellent) stones, most of us find that
we can go down lower on the color scale (G/H) and some folks even I, J and there are a few PSers with Ks out there that are
completely happy.
