Method 01
Measure a ring you already love
Choose a ring worn on the same finger. A jeweler can measure its inside diameter precisely and convert it to a standard ring size.
Ring-size guide
Find your
perfect fit.
Accurate sizing makes a meaningful difference. Use this guide as a starting point, then choose the method that gives you the most confidence.
Our strongest recommendation
Visit a reputable local jeweler and have your ring size determined professionally. It is the most reliable option, especially for engagement rings, wider bands, or a surprise gift. Some jewelers provide sizing as a courtesy; others may request a small fee for their time and expertise. Ask to be measured more than once, at different times of day if possible.
Method 02
Use a professional sizer
A reusable ring sizer is more dependable than printing a paper guide. Measure when your hands are at a comfortable, normal temperature.
Good to know
Fit should be personal
Finger size can change with temperature, time of day, and band width. A properly fitted ring should pass the knuckle with gentle resistance and sit comfortably once on.
Our fit-support promise
If your Celestra ring needs its first resize because the ordered fit is not right, we'll reimburse a local jeweler's resizing charge up to $60. Keep the receipt and contact us before arranging the work so we can confirm the appropriate next step for your particular setting.
Ordering with confidence
