Wedding band ideas. Please help!

Ooh that's a tough one. I think your best bet is going to be a curved band - maybe made to fit your ring specifically. I'm imagining something like these inspiration pics:

your other option is something that slides underneath, or doesn't connect entirely, like these:

I agree with Rosie. Curved bands made to fit your ring will add the least “bulk”. Another option would be to just not have a band! The ring is very intricate and could be worn alone. Or, you could get a band that you like on its own (not one to fit your ring) that you can wear only when you don’t feel like wearing your current ring.

Rosie has some great ideas! Maybe just a simple band underneath (or over) that matches in color that goes with the style/size. I'd recommend going to a local jeweler and see if they have anything they have that might go with your ring.
