Ring Sizing & Fit Guide

Getting the size right before production protects both you and the ring.

Celestial Rex rings are made to order, and many designs use tungsten, ceramic, or other constructions that do not resize like a traditional gold band. A later size change can require machining, replacing the underlying band, or rebuilding part or all of the ring.

Measure Before You Order

Do not rely on a guess, an old ring size from years ago, or a casual estimate. Ring size can change with finger shape, temperature, weight changes, and the width of the band.

Band Width Matters

A wider band can feel tighter than a narrow band at the same nominal size. If you are moving from a thin ring to a 6mm, 8mm, or wider band, verify your size for the width you plan to wear.

Use a Proper Sizer When Possible

A physical ring sizer or a jeweler's measurement is preferable to estimating from a printed chart or a ruler. Measure under normal conditions and, when possible, check more than once.

Initial Fit Correction

Celestial Rex intends to protect customers who make a reasonable effort to size correctly when ordering online. The final published sizing policy will distinguish between a small initial fit correction and a substantially incorrect size selection.

As a working rule, a modest correction close to the ordered size may qualify for complimentary initial correction during the fit period, while a large difference or a later-life size change may require a paid remake or replacement band.

Please Do Not Guess

Submitting a random or highly uncertain size can turn what should have been a simple made-to-order ring into a costly remake. If you are unsure, contact Celestial Rex before production so we can help you verify the size.

Later-Life Size Changes

If your finger size changes years later, we can evaluate the ring and explain the available options. Depending on the construction, that may involve replacing the band or remaking the ring rather than stretching or shrinking the original.
