It’s up to you if you want your rings to match and be worn on the same finger. Some brides will buy a wedding band to wear on a different finger or hand than their engagement ring. Or buy a plain band to wear with their engagement ring and buy a second eternity band for their right hand.
Many jewelry designers make wedding bands that match an engagement ring, which is great if your engagement ring’s design makes it difficult to find a band that lies flush against your engagement ring band.
Always check with your officiant if your wedding ceremony calls for certain types of wedding bands to be exchanged. For example, Jewish ceremonies require that the rings exchanged are solid metal with no breaks, meaning no stones. In this instance some couples will buy two bands or borrow their parents’ or grandparents’ bands for the ceremony and after put their, what I call the, fancy ring on.
Just as you did when you shopped for your engagement ring, take your time browsing and trying on wedding bands. See what feels comfortable and looks right either with your engagement ring or alone, and don’t rush the purchase. Just like your engagement ring you’ll be wearing it everyday for many, many years.
