need help deciding on setting

[DiamondCat]

My diamond is most probably going to be around 0.70ct (rb) but I have nooo idea which setting to go for.

I love plain solitaires with thin shanks and so far I have narrowed it down to 3 settings:

Mark Morrell Petite Sunburst
Leon Classic Solitaire
Vatche Swan

Which setting would suit a diamond of that size the best? Oh and my ring size is 2 3/4

Please feel free to post any other settings too!

Thanks

My vote is for the Mark Morrell. Of course, I''m biased coz I got a custom one. However, all of your choices are beautiful.
