Size Guide

Ring size guide

Every ring is made to order, so we make it in your exact size. Sizes below are US sizes; the inside circumference in millimeters is the same number as the EU size (for example, US 7 is about EU 54).

How to measure

  1. Wrap a thin strip of paper around the base of your finger, snug but able to slide over the knuckle.
  2. Mark where the paper overlaps and measure the length in millimeters. That is your circumference.
  3. Find the closest number in the table. If you are between sizes, choose the larger one, especially for wide bands such as the Wavy or Stellar rings.

Or measure the inside diameter of a ring that already fits you well.
