Knowing the ring size you need to order might be tricky. To make this easier we have an orderable ring sizer that you can use to measure your finger. Simply slide it on and zip it snug, then confirm that it will slide on and off past your knuckle comfortably. Also if your simply needing to convert your finger size from a diameter measurement or an international size see the chart below. If you're unsure at all about this process feel free to live chat with us and we will help you through the sizing!
