Ring Size Guide

Every ring is made to order in the size you choose, so the size matters more here than it does on a shelf. This page has two ways to measure at home and the full conversion table. If you land between two sizes, tell us and we will talk it through before we start cutting.

Measure a ring you already wear

This is the more reliable of the two methods. Take a ring that fits the finger you have in mind and measure the inside diameter across the widest point with a ruler that has millimetres on it. Match that number to the inside diameter column in the table below.

Measure the inside edge to inside edge, not the outside of the band. A 1 mm error at this step is roughly half a ring size.

Measure the finger

Cut a strip of paper about 5 mm wide, or use a length of string. Wrap it around the base of the finger, snug but not tight, mark where it overlaps, then lay it flat and measure to the mark in millimetres. That figure is the inside circumference — the second column in the table.

Do this at the end of the day when the hand is at its largest, and not straight after exercise or a cold walk. Fingers change size through the day by up to half a size.

Two things that change the answer

Wide bands run tight. Anything over about 4 mm wide takes up more of the finger. On a wide band go a quarter size up.
A large knuckle wins. The ring has to pass the knuckle, so measure there too and take the larger of the two readings. If the gap is more than a full size, write to us — that is a fit problem we can design around.

What we make

We cut US sizes 3 through 10 1/2 as standard, in quarter steps. That covers the great majority of hands. Outside that range is not a problem, it is just not on the dropdown — write to us with the size and we will quote it.

Ring size conversion table

Inside diameter and inside circumference are the two measurements you can take at home. The remaining columns are the national sizing systems, in case the ring you measured was bought elsewhere.

Description

A large marquise in green, set high and lengthwise, with small stones running the band up to it. This is the engagement version of the shape: bigger than the everyday marquise rings, and raised so the points sit clear of the shoulders. Choose your size when you order. Made to order in solid 10K, 14K, or 18K gold.

Materials

Solid gold, never plated — 10K, 14K, 18K in rose, white, yellow gold
Stone: Cubic Zirconia (Emerald Green)
Cut: Marquise

This is the only piece in this group with a stone, and the setting is built around protecting it. A marquise has two points and points are where stones chip; raising the stone clear of the shoulders means the tips are held rather than sitting against metal that can knock them. The small stones running up the band lead the eye to the centre instead of competing with it. Around 1.4 grams in 14K.

The centre stone is AAA Cubic Zirconia (Emerald Green), a marquise cut. It is cut in solid Gold (10K, 14K, 18K), in yellow, white or rose, hallmarked inside the band and never plated. The finished piece weighs about 1.4 grams in 14K; 10K runs a little lighter and 18K a little heavier. You will also find it in Engagement Rings, Cubic Zirconia Rings and May Birthstone Rings.
