Measure a ring you already own
Choose a ring that fits the finger you plan to wear your Aurelia ring on. Lay it flat on a ruler and measure the inside diameter, edge to edge, in millimetres. Match it to the chart.
Measure your finger
- Wrap a thin strip of paper or string snugly around the base of your finger.
- Mark where the end overlaps, then lay it flat and measure the length in millimetres. That’s your circumference.
- Match it to the chart. If you fall between sizes, choose the larger size.
Tips for the best fit
- Measure at the end of the day, when fingers are warmest and largest. Avoid measuring when your hands are cold.
- Your ring should slide over your knuckle with a little resistance and sit comfortably without spinning.
- Wider or chunkier bands tend to fit more snugly, so consider going up half a size.
- Still unsure? Contact us and we’ll help you choose.
