Ring Size Guide

Not quite sure? Let us help

In order to get started with your order, we’ll need to know the UK ring size that you would like your ring/s made in. The chart below will help if you’re converting from a different country’s ring measurement system or from actual measurements.

Before ordering we recommend that you have your finger/s measured at a local jewellers, ideally trying on a ring that is the same width as the size you intend to order, as the width of a ring can affect the way it fits over your knuckle, and therefore the size that you need. Definitely try to avoid working out ring size by using very narrow measuring ring sets, which can be either metal or plastic, as these only give you a ballpark size and aren’t accurate enough. They’re also normally much narrower than the rings to be ordered. Bits of string and rulers to measure existing rings doesn’t tend to get close enough either!
