Onyx Signet Ring - 12mm

1. Wrap a piece of thin string/paper around your desired finger.

2. Make sure the string/paper is tight but can move over your knuckle without discomfort.

3. Where the string/paper meets or overlaps, mark it with a pen.

4. Measure the string/paper in millimeters. This will give you the circumference of your finger.

5. Use the chart below and convert your measurements into US sizing.

6. If you are between sizes opt for the larger size rather than smaller. 

If you are unsure about your size or how to measure your finger, then a quick visit to your local jeweler is the best option to get your ring size correct.
