Up to 16mm by 17mm by 5mm plus band.
As this is our own design, we can adjust it to almost any size! If you know your ring size, please send an email to email@example.com before placing your order, otherwise we will send an average size. Please note that if your size is not in stock, your ring will take a little longer to get to you. We will email you to check this is ok before having a ring sized for you.
