Wedding Rings! Opinions and advice needed on cost/style

I think a twist band maybe with diamond studding would look best, at least that's what I pictured when I saw the photo of your engagement ring! However I think it would look good just plain gold twist too. My wedding band is also just plain gold and I am a fan of that look. I would recommend going to a jeweler and seeing if they can recommend a specific band to fit with your engagement ring, or maybe if they can do a custom band so that it would flush perfectly against your engagement ring. They shouldn't scratch each other if they are both made of gold (it's extremely durable) but it could just be annoying if they don't fit together perfectly.

As for the "right" price for a gold band... I have just a plain, 2mm white gold band, and it was $450. I would think that is close to the accurate pricing for what a "good" band should be, since it seems comparable to what other people I know paid, and also I really trust the jeweler we got it from.

From my personal experience, I don't think you'll be able to find a real gold band for just $200. gold can be expensive, especially when it's designed similar to your engagement ring. I think the sides of your rings may rub down the twist a bit, but there's virtually no way to avoid that. My engagement ring has a design on the bottom where my wedding ring meets it and that's kind of been rubbed down just from wearing it. I think it's totally fine if the rings aren't flush! My engagement ring has a design my wedding ring is straight across so it doesn't fit flush and I don't mind it.
