All BB Engagement and Wedding rings are made to order. Your size matters to us, so please double check it before you place your order. Size guide measuring, If you need further assistance, contact the team at BB.

Wide and cuff style rings are generally wider than a standard band. Half a size should be added to your measurement. This caters for the surface area. If you select a larger ring size, this will incur an additional cost because it requires more metal to work with and more stones where necessary.
