Ring Sizing Kit (FREE with ring purchase)
This handy ring sizing kit is free to customers* also purchasing a ring from us at the same time, but available for a nominal cost to anyone. You may purchase this sizing kit before purchasing a ring.
*LIMIT ONE PER CUSTOMER
Includes sizes 2.5 - 14. While there are only full and half sizes available in the sizing kit, we can make custom sizers and rings with quarter sizes.
Alternatives to our blue sizing kit include our free sizing app or you can visit a local jeweler to get sized in a comfort fit (unless standard fit is stated on your desired ring).
The blue sizing kit is most accurate in determining a size to order for ring designs that are 2 mm-4 mm wide.
If you have ordered a ring over 4 mm wide, we suggest using this ring sizing kit to help you determine an estimated ring size. For greater accuracy, custom ring sizers are available in the exact width and size(s) of your wider ring. We highly recommend purchasing our custom ring sizers, as they are the most accurate way to determine your ring size for the majority of our ring designs.
This sizer kit ships in 1-2 business days and includes instructions.
More Ring Sizing Info is available on our jewelry blog, which includes an international ring sizing conversion chart.
*Opt-in to receive this free kit on any product detail page at the same time you add a ring to your cart and it's free.

SIZING MADE SIMPLE
To ensure the perfect fit for your ring, it's important to correctly determine your ring size. We've created a comprehensive Sizing Guide for your convenience. This guide provides detailed instructions on how to accurately measure your ring size at home. Remember, it's always better to get your size right the first time around!
To ensure your ring fits perfectly, we highly recommend purchasing our custom ring sizers at the same time as your order. These sizers are crafted to match the width and size of your desired ring, helping eliminate sizing errors before production.
Remake Policy & Fees
If your ring does not fit, remake eligibility and fees depend on whether you used our custom sizers:
If You Ordered Custom Sizers with Your Ring:
- ✔️ If your ring arrives in the wrong size despite using our custom sizer, we will remake it for free (one-time) if returned within 30 days of delivery.
If You Did NOT Order Custom Sizers with Your Ring:
- Rings : 50% of the current retail price
- Signature Styles Collection: Eligible for a one-time exchange to a whole or half size within 30 days, subject to availability.
🔔 Important: If you choose not to use a custom sizer and determine your ring size independently, the applicable remake fee will be required if resizing is needed.
