Size Guide

You can use this chart to help find your ring size. Use a piece of paper to measure the circumference of your finger, carefully mark where the ends meet and then straighten against a ruler to measure the length in millimeters (mm). If you are in between sizes we recommend sizing up. Our rings can be custom ordered in whole, half and quarter sizes. Please note: certain sizes may affect the price. For information & pricing about custom sizing and sizes smaller or larger than listed on this chart, please contact us. If you are unsure of your ring size, we recommend that you visit a local jeweler to have your finger sized.
