Ring Size Guide
Our rings are made to European sizing. The letter shown on each product is the Australian and UK equivalent, and the EU number is printed after it so there is never any doubt about what gets made for you.

How to measure at home
Wrap a strip of paper around the base of your finger, mark where it overlaps, and measure the length in millimetres. That figure is your inside circumference — match it to the table above.
Measure at the end of the day, when your fingers are at their largest, and make sure the strip slides over your knuckle. If you fall between two sizes, take the larger one.
Rings listed as Adjustable need no measuring at all: they open at the back and fit most fingers.
