Ring Size Guide

To ensure your ring is an impeccable match, we craft each piece to standard US sizing. This guide provides three refined methods to help you determine your size with confidence and precision.

Three Paths to Your Perfect Fit

1. The Professional Measurement

For unrivaled accuracy, we recommend visiting a local, reputable jeweler. A professional fitting is the most reliable way to determine your true size and is a service most jewelers are delighted to offer.

2. The At-Home Method

Wrap a thin, non-stretchy piece of string or a strip of paper snugly around the base of your finger. Mark where the end meets, then lay it flat against a ruler to measure the length in millimeters (mm). This measurement is your finger's circumference.

3. The Ring Sizer Tool

A dedicated ring sizer offers a simple and precise way to measure at home. Follow the instructions provided with your tool, ensuring a comfortable fit that can still slide over your knuckle without difficulty.

A Note on Comfort & Precision: Your ring should feel secure, yet slide over your knuckle with ease. For wider bands (over 6mm), we often recommend selecting a half-size larger for optimal comfort. Should you have any hesitation, our client advisors are always at your service.
