What Diamond Shape Looks Best in a Three Stone Ring?

I’m looking at different diamond shapes for a three stone ring and can’t decide which one looks best. Round, oval, emerald, pear, and cushion all have their own style. If you’ve bought one before, which shape did you choose, and are you happy with it?
