Ring sizing, done once

Measure at the end of the day when fingers are at their largest, and measure the same finger you intend to wear the ring on.

Three ways to measure

Existing ring: measure the inner diameter in millimeters across the widest point and match it to the chart.

Paper strip: wrap a 6mm strip around the base of the finger, mark where it overlaps, and measure the length in millimeters — that is your circumference.

Free sizer: request a reusable ring sizer with your appointment inquiry and we mail it at no charge.

Wide bands over 5mm and full eternity rings run tight — size up a quarter to a half. Eternity bands cannot be resized after setting, so we confirm sizing twice before casting.

First resize within 12 months is complimentary
