Not sure about your size? Use our guide below to find the perfect fit. All LUME NOIRÉ rings are available in US sizes — find your EU equivalent and measure your finger at home.
How to Measure Your Ring Size
1. Wrap a thin strip of paper or string around the base of your finger.
2. Mark where the paper meets and measure the length in millimetres.
3. This is your finger circumference — match it to the table below.
Tip: Measure in the evening when fingers are slightly larger, and ensure the size fits over your knuckle.
