As a guide, ring sizes J to X are of the approximate measurements (in millimetres)
These rings are made to your exact order so can be made in smaller and larger sizes depending on the style required.
Once your order has been placed online, we will contact you by email to confirm the size you require.
If you need a size slightly different to the J to X sizes above, please tell us in the 'Your Notice To Us' provision which appears on the same page as the one where you tell us your name and address.
