How to find your ring size.
There are two ways to find your ring size.
1. Measuring a ring that fits you already.
- Measure the inner circle of your ring directly across the mid-line.
- This gives you the Diameter.

1. Measuring directly from your finger.
- Cut a thin strip of paper.
- Wrap it TIGHT around your finger.
- Mark where the paper meets/overlaps.
- Lay the paper flat and measure the full distance.
- You now have your Circumference and can match up to the correlating size.

Signet Rings are not resizable.
If wrong size is ordered a new ring will need to be made from scratch.
This will take 3-5 weeks.
