Ring size guide
Our rings use EU sizing: the number corresponds to the inner circumference in millimetres. Use a ring that fits the same finger to find your size below.
How to measure
Measure the inside diameter of your ring, from one inner edge to the other through the centre. Do not include the metal. Compare the measurement with the table; the diameters shown are approximate.
A comfortable ring slides over the knuckle and sits securely at the base of your finger. Measure when your hands are at their usual temperature. Wider bands can fit more snugly; if you are unsure, have your size checked in a boutique.

Size availability varies by design. Measurements are a guide; an in-person fitting gives the most reliable result.
