Vuittonslover - you're definitely not wrong, I think that's why they launched their pear shapes in just the plain "diamonds by the yard" bezet style without the halo! You have good taste!
But for me... There is something about the sola/soleste with the yellow surrounded by more sparkly white diamonds that just took my breath away the moment I saw it. Not sure why but plain yellow diamonds with nothing around them just don't move me as much... I guess I want more sparkle! Plus my ring (which I adore) is a solitaire, so I'd kind of love to have something with a halo for a change. PLUS... for the size I want it to be (which really isn't going to be THAT big - it'll be smaller than the pear ring I pictured, which is 1.25 carats (the yellow diamond, plus .40 in whites), I'd have to get a really big (ie expensive!) yellow diamond!!
