However, when purchasing a ring from Wallace Bishop we always want to make sure that it fits you perfectly. So if one of the above sizes is not perfect for you, your new ring can easily be re-sized by our master jewellers at our state-of-the-art workshop.

Simply present your new ring and receipt at any Wallace Bishop store and we can discuss the options available to you.
