About the ring
Archetype: Off Axis
A triple knife-edge bypass setting.
Commission with Sital Jansson
Complimentary cleaning and inspection for life. One year craftsmanship guarantee, terms apply. Resizing assessed case by case.
Every ring is made to order in US sizes 4 to 11, including half sizes. You can find your size at home, with a ring you already wear or with a strip of paper.
Measure a ring you already wear
Choose a ring that fits the intended finger well. Measure the inside diameter in millimetres, straight across the centre of the band. Then read your US size from the table below.
Measure your finger
Wrap a strip of paper or a length of string around the finger and mark where it meets. Lay it flat and measure the length in millimetres: that is the circumference. Measure at the end of the day, when fingers are at their largest, and be sure the ring will pass over the knuckle.
