International Ring Size Chart

Below is a chart of ring sizes to help our international customers figure out how sizes match up. If you intend to purchase a ring with trim or a wide fitting ring we suggest you go up a 1/2 size than your normal ring size for e.g., if you are normally a size 6 then you would need to order a size 6 1/2 (6.5).
