We want you to feel completely confident when you shop with us. That’s why we offer FREE 30-day returns for refunds and 60-day exchanges across the UK and Northern Ireland.

If you’ve ordered a ring smaller than a size J or larger than a size Q, don’t worry — these are custom sizes, but we’re still happy to offer a free exchange or resizing if the fit isn’t quite right.

Cancelling an Order Before Dispatch

Changed your mind? No problem — you can cancel your order anytime before it’s been dispatched.

Just reach out to our friendly team via Live Chat, by email at customerservice@thediamondstore.com, or give us a call on 0345 084 1200 (or +44 345 084 1200 if calling from outside the UK). Please have your order number handy to help us assist you as quickly as possible.

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.

Our 5 Year Warranty.

We stand by the quality of our jewellery. That’s why all our pieces come with a 5-year warranty against defects in materials or craftsmanship. Every item is also fully hallmarked according to UK legislation, confirming its authenticity and origin.

We’ll always refund you via the same method you used to make your purchase — whether that was credit or debit card, PayPal, Pay4Later Finance, bank transfer, or another option.

To avoid delays, make sure to include the returns label print-out with your parcel. This helps us identify your return quickly.

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.
