Ring Resizing Policy

Our two-year warranty includes one free resizing within that period. However, not all rings can be resized, and there are limits to how far a ring can be adjusted. To find out if we can resize your ring for you, contact us–we’d love to help!

Ring Size FAQs

Certain rings, like eternity bands, cannot be resized at all. Other rings, like intricate pavé designs, may be able to be resized a little, but not a lot. To find out if your ring can be resized, just reach out to our team!

Our warranty is good for a full two years, so if you haven’t had your ring resized yet and it is still in the warranty period, we would be happy to resize it for you. (You just pay to ship it to us, and we’ll take care of the rest!) It is normal for fingers to change sizes over time, so it’s not uncommon at all to need a size adjustment at some point. We make it as easy as possible, so you can get your ring back on your finger where you can enjoy it!

Yes! If you find you are in between two half sizes, we can make your ring in a quarter size. The drop-down size selectors on each ring product page have quarter-size options for you to choose from.

For women, the average finger size is around 6. For men, the average finger size is closer to 9. Taking all genders into consideration, the average adult finger size is around 7.5. This can vary widely, however.

If it is not a surprise, you can order a ring gauge to get the right size at home. If you are going for a surprise, it may be a little more complicated! You could ask one of their close family members or friends or borrow their ring and trace it onto a piece of paper if they already wear a ring on that same finger. For more tips, check out this article on how to find out someone’s ring size without them knowing.
