Maybe it''s a long shot, but if someone has seen a setting like this in platinum, please let me know.
Here''s option 1 - we wish the side stones were larger, and wish the actual construction of the setting (as shown in the side view) was more like the one below (though the band would fit closer on this one). Ignore the diamond size for now, only approximately correct:

The three stone setting below is under consideration too, though we''d prefer a band more like the one above (squarish) and the side stones might be a little large. The side view of this ring seems better (the way the setting is constructed).
