Size Guide
We strongly encourage you to visit your local jewellery store to have your finger measured by a professional jeweller.
If this is not an option for you, we recommend to measure an existing ring.

- Use a ruler to measure the inner diameter in millimeters from one side to the other.
- Use the chart to find your corresponding ring size.
