Size Guide

When sizing a ring, it is worth considering several factors:

Thickness A thicker ring will displace more of your finger, creating a tighter fit than a thinner band. If you are certain of the size in a thinner band, we’d suggest going half a size or possibly a size bigger.

Temperature In warmer weather our fingers swell, in the cold they contract. A ring that fits in winter might feel a little more snug on holiday in a hotter climate. When trying on a ring consider the temperature of your hands. We recommend trying a ring for size when your hands are at a moderate temperature.

Finger shape A wider knuckle might require a tighter ring which is slightly difficult to push over the knuckle but fits nicely at the base of your finger.
