To ensure your ring fits, simply use a ruler to measure the inside diameter of a ring that already fits and refer to the Ring Size Guide below. Select the ring size that is closest to your measurement. If you are unsure, please don't hesitate to contact us. We love hearing from you! We will happily exchange your ring for another size if we have it in stock.
