Hi! Ring sizing can be tricky and is a surpisingly personal choice! Some people wear their rings loose, some tight. If you do not know your ring size, we highly recommend having your finger sized by a local jeweler and asking for your US ring size. You can also try this PDF or you can order a ring sizer here. If you’ve ordered with us before and would like a refresher on your ring size, please email us — we’re here to help!
