Ring Size Information
Back to Top- The ring i want to buy is a surprise, so how am i meant to get her ring size?
To get an accurate ring size is very unlikely, your best bet would be to purchase the ring then have it re-sized after your proposal. - Do you charge to resize a ring?
Yes if you have asked for a ring to be made a certain size and found out that it does not fit then we do charge a fee of £50. Please note: Rings that have diamonds all the way round cannot be re-sized. But if you were uncertain of the size and we made the ring to an average ladies finger size then we do not charge for changing the size. - What is the best way to measure my ring size?
You could pop into your local jeweller. But if that is not possible then it would be best to request a ring sizer below.
