Ring Size Guide
Made to order in the size you choose. If you're between sizes, size up — a ring can be brought in later, but one made too small can't be worn.

How to measure
- Use a ring you own. One that fits the right finger. Measure the inside edge-to-edge in millimeters and match the Diameter column.
- Or use string. Wrap a thin strip of paper or string around the base of your finger, mark the overlap, measure in millimeters, and match the Around finger column.
- Measure warm. Fingers shrink in cold and swell in heat. End of day, room temperature, is truest.
- Mind the knuckle. If it's wider than the finger base, size to slide comfortably over the knuckle.
Still unsure? Email care@houseofestara.com with your finger circumference in millimeters and we'll size you.
