How to find your size
- Take a ring that fits the finger you want to wear it on.
- Measure the inside diameter, edge to edge, and pick the closest size above.
- No ring at hand? Wrap a thin strip of paper around the base of your finger, mark where it overlaps, and measure that length: it is your circumference.
Measurements are the maker’s. Your own measurement always takes priority over a size label.
