Ring Sizing

What is the best way to find out your ring size?

The best way to determine your ring size is to visit a local jeweler and have your finger professionally sized. Be sure to tell them the width of the ring you are ordering, as wider rings fit more snugly. For tapered rings, use the width at the back of the ring when determining your size.

For the most accurate fit, have your finger sized with a ring sizer that is the same width as the ring you are ordering. For example, measuring with a ¼ inch wide sizer for a 3/8 inch wide ring may result in a size difference of approximately ¼ to ½.

Can a ring be resized?

If a ring is slightly too tight or too loose and has no settings, inlays, or onlays, it may sometimes be possible to stretch or dome it slightly to adjust the fit. This should be done by a jeweler and often only takes a few minutes.

For larger adjustments, a jeweler will need to resize the ring by cutting the ring and adding or removing a small amount of metal, then soldering it back together. Many of our rings include a sizing gap at the back for this purpose.

Because every ring is different, we recommend consulting a professional jeweler before deciding on any resizing method.
