Ring size guide
Finding a comfortable ring size is simple.
How to measure at home
1. Wrap a thin strip of paper or soft string around the base of your finger.
2. Mark where the ends meet, then measure the length in millimetres — that is your circumference.
3. Match the millimetre measurement to the chart below (US / HK common sizes).
If you are between sizes, choose the larger size for comfort, especially for wider bands.
Prefer a precise fit? Bring a well-fitting ring of similar width to a jeweller, or message us and we will guide you gently through the process.
