Soooo...... Thanks to everyone who voted! I ended up picking the setting that most people voted for, so I guess my gut feeling was right! :-)
ALTHOUGH.....I was totally seduced by the beauty of a light charcoal grey rose cut diamond!!!!
I´m going to be leaving my OEC dreams for my next project because an elongated east west rose cut just looks SOOOOOO right with this setting.
Jill is going to help me look for the right stone. I´m wavering between either a light charcoal grey with some translucence or a creamy beige, also with some translucence.
Creamy beige like the one in the center, yet a not so opaque...

OR
Light charcoal grey like the one in the bottom center

In either case, the setting would be the one with the bezel in 22k, with a mini granulation halo, and a diamond accented granule on either side with the 18k shank, (like the creamy beige rose cut ring)
Any opinions as to which might look better with 22k?
Thanks for your feedback everyone!!
