Ring Size Guide

Choosing the correct ring size is at the discretion of the customer as some prefer to wear them loosely, while others wear them tighter.

The thicker the ring, the tighter the fit. So if you choose a ring with a deep band width, you will likely need to go one size up.

Here is a fail-safe method to help you determine your right size. Quick tips: measure your ring size at the end of the day when fingers are at their largest, and do not measure your hands when they are cold as they may have shrunk up to half a size.

Using one of your favourite rings, measure the inner diameter of this ring (in millimetres), match it to the options in our ring size guide below and you will be able to find your ideal size. If your ring falls between two sizes, we recommend selecting the larger size available.
