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.
Damaged or Defective Items
If your item arrives damaged or defective, we’ll make it right — fast. We’ll either repair or replace it at no cost to you, or provide a refund once it’s been assessed by our head jeweller.
Our standard returns policy is 30 days to return, and 60 days to exchange.
Our 5 Year Guarantee.
We stand by the quality of our jewellery. That’s why all our pieces come with a 5-year guarantee against defects in materials or craftsmanship. Every item is also fully hallmarked according to UK legislation, confirming its authenticity and origin.

5 Year Guarantee
The Diamond Store prides itself on its superior jewellery. Ours is skillfully and carefully crafted to last a lifetime and longer.
We guarantee that….
Any defect in the craftsmanship of our jewellery is fully covered for 5 years from purchase.
If a fault or a defect is found in the way our jewellery was crafted, we will correct the defect or exchange or remake the jewellery at no cost to you.
Please know, whilst our jewellery is robust to suffice daily wear, it is not a maintenance free commodity. Care needs to be taken with all jewellery, especially rings that contain gemstones all the way around.
Our diamonds are conflict free.
Our silver, gold and platinum jewellery is hallmarked in the UK.
Our jewellery is backed by a 30-Day Money Back Guarantee (except when we make an item especially for you).

Please note that our guarantee does not cover accidental or intentional damage or loss caused by the customer or a third party.
It also does not cover any jewellery that has been taken to another jeweller or craftsperson for work, alteration or resizing.
We can give you some real life examples that have not been covered by our guarantee: such as catching a ring on a door frame, accidentally dropping an earring into a waste disposal container or vacuuming up a bracelet.
If anything does happen to your jewellery, whether it’s your fault or ours, the best thing to do is send it back to us for an assessment. We will then either repair the item for free under our guarantee, or we will charge you a small fee for the repair if the damage was caused by you. We will always be forthright and let you know beforehand if there are any charges.
One way or another we will always do our utmost to help.
WHAT OUR GUARANTEE COVERS
All repairs and postage costs for any problem that can be attributed to the way your item was originally made.
WHAT OUR GUARANTEE DOESN’T COVER
Any loss or damage to your jewellery caused by you, or by another person’s actions.
WHAT IF I ACCIDENTALLY LOSE OR DAMAGE MY JEWELLERY?
Jewellery insurance with worldwide cover including accidental loss or damage is available through our recommended expert partners, Assetsure. Find out more about jewellery insurance.
Is the jewellery sent in plain packaging?
To keep your surprise safe, the outer packaging that we deliver your jewellery in is plain.
On the outside, our plain postal package does not say The Diamond Store anywhere, nor state what the contents are.
So if you’re buying a gift for someone who lives in the same address as you, your secret will remain safe – as long as they don’t open the package!
On the inside, however, you’ll find your beautiful jewellery, along with our stylish gift presentation set, ready for your special occasion.
(We’re also proud to say that our sustainable packaging is Forest Stewardship Council approved, which means its production hasn’t harmed the world’s forests – find out more here.)
Watch the video below or click here to discover exactly what’s inside the inner gift presentation box.
Our Gift Message Cards
When you purchase any item of jewellery from our website, you can choose to include a FREE personalised gift message card with your order.
Along with our elegant, free gift packaging you’ll be able to personalise one of our stylish credit card sized gift message cards to include with your order.

HOW DOES IT WORK?
Once you have completed checkout, you’ll reach the Order Confirmation Page.
Here, you’ll be prompted to request the free Gift Message Card.
Simply write your message in the space provided, and submit it. We’ll make sure the card is included with your order.
CAN I WRITE ANY MESSAGE ON THE CARD?
You’ll be able to personalise the card with a message of your choice, up to the space available.
However, we can only print the British alphabet and numbers from 0 to 9, and no special characters or emojis are supported.

DO YOU ALSO SUPPLY GIFT PACKAGING?
Yes, beautiful presentation of your jewellery is very important to us. We want you to feel delighted when it arrives!
That’s why every item we sell comes nestled within one of our FREE exclusive gift sets, while the outer packaging is plain so as not to spoil any surprises.
