I am so happy and pleased that we decided to order this ring! We bought this to use as my wedding band. Everything about this ring is beautiful and perfect. We purchased the 4.5mm and it is very comfortable. We ordered the ring sizer prior to purchasing the ring and it was an excellent guide in picking the right size. The cost was also very reasonable and we are planning and getting a second one for my husband because this ring is such a showstopper.
