FINDING YOUR FIT
For the most reliable fit, ask a jeweller to measure your finger with a proper gauge or measure the inside of a ring worn on the same finger. Band width and profile can affect the result.
These UK, millimetre and approximate US equivalents are a guide. For more measuring advice, read the full Ring Size Guide.
