The standard sizing for rings is J - Q. As I am dealing with UK jewellers many rings come in smaller or larger sizes than I have listed. It is advisable to have your finger measured before placing an order. I would also recommend emailing or telephoning me to check availability as I do not stock all sizes of all the rings I sell. 01985 511609 / 07747 047083 so please do not order these as a next day Special Delivery. For rings larger than a size Q I will have to check it is possible to have the ring either made bigger or specially made from scratch for you. There may well be a 4-6 week wait for this type of item.
