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 firstname.lastname@example.org 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.
