Size Guide
The most accurate way to determine your ring size is to stop into a jewellers and get them to measure your finger but if not, follow this handy method below.
If you already own a ring:
- Select a ring that fits the finger you plan to wear it on.
- Place the ring on a flat surface.
- Using a ruler, measure the inside diameter of the ring from one side to the other, in millimeters.
- Compare your measurement with our size guide to find your ring size
If it is your first ring:
- Cut a strip of paper or string.
- Wrap it around the base of your finger where you’d like the ring to sit.
- Mark where the paper or string overlaps.
- Measure the length (circumference) with a ruler and refer to our size guide below to find your size.
- Repeat to double check.
