I was scared of buying such an expensive ring from a website - especially not knowing my exact size. I got a lot of help from Alex in customer support. She sent me a ring sizer immediately and helped me convert the size to American sizes (since my ring was from there). After it arrived and it was slightly too large then Alex quickly arranged for it to be picked up and resized. It took about a week longer and I got it back in the perfect size. Really happy with the customer support and with the ring.
