For comfortable daily wear, I like a simplistic semi-bezel setting that will protect the girdle. I think almost any shape looks great in a setting like that.
I love the Swan 3-stone pave, Ames'' ring, wide diamond bands with lots of twinkling little diamonds, antique halo settings...picking a favorite is just not possible. Rings are wearable art!
My setting but with a princess cut! Now that I''ve had my setting for a while and do love it with a RB, I really think it needs a princess cut! Someday
For an emerald cut- Tacori-eirng setting and iloveny''s. Both are the perfect settings for an EC!
For a round, both my setting and the Cartier solitaire (or WF''s Fine Line copy) are my ideal RB setting.
