Size Guide

Precision Fit for Every Piece

Our size guides are crafted with the same precision as the pieces themselves. When in doubt, our client advisors are always available to assist.

01 · Ring Size

Measure the inner circumference or diameter of an existing ring, or wrap a strip of paper around your finger.

01

Existing Ring

Place your ring on a ruler and measure the inner diameter in millimetres.

02

Paper Strip

Wrap a 6mm strip of paper snugly around your finger, mark where it overlaps, and measure the length — that is your circumference.

03

Best Time

Measure in the evening when fingers are at their largest. Avoid cold or early morning measurements.

* Pendant drop adds approx. 2–4 cm to the visual fall. Factor this when choosing length.

03 · Shoe Size

Measure your foot length from heel to longest toe while standing. We recommend measuring both feet and using the larger measurement.

Place a sheet of paper on a hard floor, stand on it with your heel against the wall, and mark the tip of your longest toe. Measure the distance in centimetres, then match below.
