Yes, we offer returns on engagement rings within our standard return period. This gives you peace of mind if the ring isn’t quite right. For full details, please see our returns policy (https://www.thediamondstore.co.uk/policies/refund-policy) or contact our customer service team (https://www.thediamondstore.co.uk/pages/contact-us).
The best metal depends on your style and lifestyle. Platinum engagement rings are durable and naturally white, making them ideal for everyday wear. 18K white gold offers a bright, modern look, while 18K yellow gold provides timeless warmth. All of our metals are recycled and chosen for both beauty and strength.
Don’t worry - it’s very common not to know your partner’s size when planning a surprise proposal. You can secretly measure a ring they already wear or ask a close friend or family member for help. Many of our engagement rings can also be resized later, and we allow you to take advantage of our generous return and exchange policy, too.
Yes, many of our engagement ring designs have matching wed-fit wedding bands available. These are crafted to sit perfectly alongside your engagement ring, creating a seamless bridal set. Our collection includes plain, pavé-set, and shaped bands to suit your chosen design.
Every engagement ring over a certain carat weight comes with a certified diamond, graded for the Four Cs – cut, colour, clarity, and carat weight. We also provide IGI or GIA certification for many designs, giving you full assurance of quality and authenticity.
In many cases, yes. Most classic engagement ring designs can be resized, though certain eternity bands or intricate styles may not allow it.
When you return your ring to us, if resizing isn’t possible, we’ll issue a replacement ring in your desired size instead. This is the best approach for the majority of orders.
If you would prefer your original ring to be resized, usually for sentimental reasons, please let our Customer Service team know when you get in touch. We’ll do everything we can to see if this can be arranged and will keep you informed throughout the process.
We don’t currently offer bespoke or custom-made rings. However, our collection includes a wide variety of engagement, eternity, and wedding rings in different styles, metals, and precious stone shapes and colours — giving you plenty of choice to find a design that feels personal and unique to your story.
Delivery times depend on the design and sometimes size of the ring. Many of our diamond rings in standard sizes are available for fast or even next-day delivery. Estimated delivery times are available on the product pages, but you can always reach out to our customer services if you’d like to know the lead time on a specific item.
Yes, every ring comes in a luxury presentation box, perfect for gifting or marking life’s special moments.
We offer both lab-grown and ethically sourced natural mined diamonds, so you can choose the option that best suits your budget and values. All natural diamonds are sourced in line with the Kimberley Process to ensure they’re conflict free, and all our stones are set in recycled precious metals.
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.
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.
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.
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.
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.
Once we’ve received and inspected your returned jewellery, we’ll process your refund right away and email you to confirm. Depending on your bank or payment provider, it may take 3 to 5 working days to show up on your statement.
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.
We’re proud to say that all our diamonds are conflict-free and fully compliant with United Nations regulations. When you buy from us, you’re choosing ethical beauty.
We’re here whenever you need us.
