It is essential to get your ring size correct when placing an order. Due to the nature of the milk stone, some jewelers will refuse to re-size your ring.Please have your ring size professionally measured at a jeweler before placing your order. Ring sizes listed are standard US sizes. International customers can have their jewelers convert sizing. I am unable to change your size once your order has been placed.If you choose to re-size the setting using a jeweler local to you, please note the ring can not be exposed to moisture, extreme heat, chemicals, and cannot be placed in an ultrasonic. Mamma's Liquid Love will not be held responsible for any damage incurred while re-sizing your ring.
