Oh.. hello. I'm sorry? I don't quite understand the question? You see.. I can't SEE the stack behind that DOOR KNOCKER!!!!!!! [wipes drool]. It's gorgeous.
Your solitaire looks lost in the stack. I think it's the top band that doesn't quite work. Something that doesn't curve would work better, in my opinion. Your solitaire and the bottom band are spectacular, though.
I love the rings..I would put the top one in the middle. Your gorgeous ering would be on top. The same diamond bands together make the curvy one look like it doesn’t belong.
To me the bottom straight band is at odds with the swoopy top band so I’d stack one or the other but not both. I’m also seldom a fan of bracketing the main ring as it often gets lost in the other rings.
