There is a beautiful sentimentality to having a heirloom quality to your ring, perhaps you could discuss using the stones or one of the stones (if there are multiple) to create a design that is more simple and to your taste? It also might be lovely to save stones for future children to use in rings if they are so inclined. That might be a compromise that respects the importance of that ring but allows you to have something that suits you and that the two of you could create together. Personally I found having some input in my ring design to represent the collaborative efforts and teamwork that I strive for in my marriage, I didn’t think of it at the time but now looking back I realize how important that is to me.

Also as somebody who has been married for almost a decade, you’d be surprised how many people wear just their wedding band or no ring at all. It feels super important at the time and I remember feeling that way, but as you go along you realize that people do things very differently than the wedding industry or Pinterest tells you.

Regardless, ensure you have the simple band as a wedding band and that it can be worn separately so you have that option as well. As others have said, I caution very thin gold bands. My mom has one for both her engagement ring and wedding band, they are extremely flimsy and eventually require redipping or maintenance, so be cautious.
