Where would you go for the best round diamond ~0.50ct?

[ringmaven]

I am working on a three stone ring, and the centre stone will be around 0.50 carats and the side stones will be 0.25 carats. I want them to be at least a G in colour, with a perfect cut, and great clarity. My thinking is that, at this small size, I can afford to by a truly exceptional stone. I want these babies to POP!

Got any advice for a newbie? I mean, I can go to bluenile and adjust all the ratings and blindly buy a presumably gorgeous stone. But is there a better way, that I'm not aware of? Thanks in advance for any suggestions!

Among these diamonds you will be hardpressed to which is best in cut quality and performance.

WOW! I Love the one you linked to! It looks really divine. You've given me some ideas as to how/where to search, many thanks!!

Is it weird that I can't see the inclusion on the SI1?
