Size Guide
Take a ruler to measure in millimetres (mm) the inner DIAMETER of a ring that you've already owned.
Using the International Ring Size Chart, you can convert your ring size to find your corresponding EU size.

Option 2: Measure Your Finger
- Take a strip of paper or a piece of string and wrap it around the finger where you want to wear the ring.
- Mark where it overlaps, then measure the length in millimetres.
- Use the finger circumference measurement to determine your size with a ring size conversion chart, or contact us for assistance.
