Get the fit right
We make our rings in Australian and UK letter sizes, from J to U, in half sizes. That is the system we use, and the one to order in. If you know your US or European size, the chart below converts across. Every ring is made to order in Melbourne, so we cast it to the size you choose. Browse our 9ct gold rings and sterling silver rings.
01
Cut a thin strip of paper or take a piece of string. Wrap it around the base of the finger, snug but not tight. Mark where it overlaps and measure that length in millimetres against a ruler. Match it to the circumference column below.
02
Take a ring that already fits the right finger. Measure straight across the inside, edge to edge, in millimetres. Match it to the inside diameter column below. This is usually the most accurate method, and the best one if you are buying a gift.
Fingers swell through the day and in warm weather. Measure in the evening for the truest result. If you land between two sizes, take the larger one.
Order in the AUS / UK column. Australia, the UK, Ireland and New Zealand share the same letter scale. US and European sizes are the closest equivalents, given for reference. European sizing is the inside circumference in millimetres, which is the ISO standard.

A note on conversions. The letter scale and the US number scale do not line up exactly, so the US column is the nearest equivalent rather than an exact match. Millimetres are the only exact measure. When you are converting, match on diameter or circumference rather than on the number.
We will send you a sizer at no cost. It reads in whole and half letters, matching the sizes we make. If you land between two, size up.
A wider band takes up more of the finger, so it can feel snug at your usual size. On the Baxter and the Dome, consider going up half a letter.
We can make smaller and larger, and we can make quarter sizes on request. Get in touch and we will make it for you in Melbourne.
If the fit is not right, we resize within 30 days of delivery. Every piece also carries a 12-month warranty.
Wrap a strip of paper around the base of your finger, mark where it overlaps and measure the length in millimetres. Match it to the circumference column in our chart. Or measure across the inside of a ring that already fits and match it to the inside diameter column. For the most accurate result, order our free ring sizer.
Take the larger size. Our rings come in half sizes from J to U, and we can make quarter sizes on request if you need something in between. Just get in touch.
Find your US size in the chart and read across to the AUS / UK column. The two scales do not line up exactly, so if you can, match on inside diameter or circumference in millimetres instead.
Often, yes. A wider band covers more of the finger and can feel snug at your usual size. On the Baxter and the Dome, consider going up half a letter.
Borrow a ring they already wear on the same finger and measure across the inside in millimetres. Match it to the inside diameter column. If you are unsure, size up, as we resize within 30 days of delivery.
Yes. We resize within 30 days of delivery, and every piece carries a 12-month warranty. Contact us to arrange a resize.
