*If your determined size is between two ring sizes, please select the next larger size.

*For any size (smaller, larger, or half) that is not provided above, please contact us

*If you already have a ring that fits you, you can measure its diameter with a ruler. The table above helps you to determine the corresponding ring size for your measured diameter.

1. You can easily determine your own ring size with a measuring tape or a cord. To measure, simply place the cord (or the measuring tape) around your finger tightly. The ends of the cord should be marked.

2. By using a ruler you can then measure the marked cord and get your ring size in circumference.


3. To find the ring size, please check above size chart.
