Ring Size Guide

Whether you're shopping for yourself or looking to bring joy to someone's day, we're here to steer you in the right direction, please follow the steps below.


1. Grab a tape measure or strip of paper.
2. Wrap it around the finger you will wear your ring on and mark where it joins.
3. Lay the paper strip on a flat surface and use a ruler to measure the length. 


If you're in between sizes, we suggest to go the larger size for a ring. It's easier to size down than to size up later.
