Product Measurements

Please note that for rings smaller than size J or larger than size Q, the width may vary slightly (up to 10%) due to the crafting process. If you need any adjustments, we’re happy to help.

RING SIZES & RINGS SIZERS

WHAT IS RING SIZE?

‘Ring size’ is a measurement that refers to the inside circumference of a ring. It’s important to know your correct ring size before buying a ring, otherwise it won’t fit properly.

Different countries use different standardised systems for denoting ring size.

On the right, there’s a chart with the 3 most common ring size systems used in UK, USA and internationally. For Australian sizes simply refer to the UK sizes, which are the same.

WHY USE A RING SIZER?

Ring size is one of those things we think we’ll always remember… but never actually do!

It is very important to find out the correct ring size whether the ring is for you or another person. This measurement enables us to provide you with a perfectly fitting ring. A ring that is so small you cannot get it on – or so big it falls off – can really ruin a big moment!

OUR RING SIZER APP

Our free Ring Sizer App is accurate and easy to use!

Find out a ring size in UK, EU or USA measurements. All sizes F – Z included, from smallest to largest finger.

Simply place your loved one’s existing ring on your phone screen, then adjust the circle until it fits the inside of the ring exactly.

This app helps you keep an engagement ring or a special gift a surprise and saves you a trip to the jewellers.
