You might want to consider matching the metal or shape of your rings, so that they are a set in themselves – as a symbol of your relationship.
If you want to go this route, it's important to keep in mind that there are many different ways to match your wedding bands. You may want them to be the same metal, or the same shape. You could even match the shape of the ring with your partner’s ring so they fit together perfectly.
Whatever you decide, whether it's just one ring or both rings together as one unit, just remember: this is an expression of love and commitment between two people who are going into marriage together – so make sure it feels right for both of you!
