Solitaire Engagement Rings with Mined or Lab-Grown Diamonds

A solitaire engagement ring - a single stone on a simple band - is considered a classic engagement ring style, and for good reason. The clean design enhances the stone's cut and sparkle, often making it appear larger and more luminous.

In this collection, you will find the stone takes centre stage. Choose from silver, platinum, and gold solitaire engagement rings - consciously crafted from recycled precious metals and set with either ethically sourced, conflict-free mined diamonds or lab-grown diamonds that match in brilliance, beauty, and quality. We also offer a range of diamond cuts, including the timeless round cut that maximises brilliance and fire.

Browse our solitaire engagement rings and find one that puts your love - and your diamond - at the heart of it all.

Our Returns Policy

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 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.

How Refunds Work

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.
