Measure the circumference of your finger and use the size chart below to identify the correct ring size. For the most accurate result, we recommend visiting a professional jeweler to have your finger measured.
It’s essential to measure your finger multiple times, on different days and at various times of the day, as finger size can change. If your measurement falls between two sizes, we suggest choosing the smaller size.
After measuring the circumference in millimeters, locate the matching measurement on the chart and select the corresponding ring size.
