Your ring is gorgeous! Is that an antique Asscher/emerald cut? It looks like the setting is high enough to have your wedding band be flush against your engagement ring. I would suggest trying different ones on to see what the height of the band should be. You don’t want it rubbing on the basket. It doesn’t look like that would be the case since your ring is set high. I would also suggest you keep the metals the same..If it’s platinum..get a platinum wedding band. Another thing is be careful with exposed diamonds on your wedding band rubbing into your basket. The diamond girdles will chew into the metal prongs... I’m sure there will be many suggestions coming. It’s a beautiful diamond and setting.
Your engagement ring is SO beautiful! A plain gold band, matching the shank of your engagement ring, would set it off nicely and not draw the eye away from the diamonds.
