Ring side Guide

I know the finger size for the ring I am ordering

If this is the case then please select the correct size from the drop down on the ordering page. The size options are from the ‘British’ system – if you are using another system then please consult the table below to determine the size to select. We may have to charge for resizing a ring. Please contact us if you need some assistance.

I don’t know the finger size to order

If this is the case, then please select the ‘Dont know’ from the finger size drop down. Once your order has gone through we will make contact with you and consult with you how we ascertain the correct size. This can be done in a number of ways including sending samples and we will be happy to help you with this.
