My wedding ring, now 43 years old, was a Christopher Wharton design. Over the years my husband has bought me two more which match the square design of the first. All these years later I have arthritic fingers and on a number of visits they have expanded all three to fit over my enlarged knuckles. On every occasion the work has been done beautifully and it is never possible to tell that they have been altered. The staff are unfailingly friendly and helpful (including a recommendation of lunch in St Albans) and the work is always completed quickly. Many, many thanks.
