From what I have seen most rings don't have a specific matching band made for them, but that makes it that much more fun!!! You can pic out a simple engagment ring and find something interesting for the wedding band. Also, with a co-ordinating but not matching wedding band you can shoot for something snazy like an eternity band which can be like total WOW! and be worn by it self.
Great advice! That is exactly what I did---I have a simple solitaire engagement ring, but my wedding band is vintage inspired with diamonds. You can do practically anything you would like to fit you personal style!
They do not necessarily come with a matching wedding band. You can select one out of the wide range of bands available these days. You can even get it customized, if needed.
