Silver, Platinum, and Gold Princess Cut Engagement Rings

With sharp, clean lines and a modern vibe, a princess cut engagement ring delivers exceptional fire and brilliance — making it one of the most sought-after diamond cuts.

Each ring in our collection is consciously crafted from recycled precious metals, with bands available in platinum, silver, and 9k or 18k gold. You can choose between conflict-free mined diamonds or lab-grown diamonds that are chemically and optically identical, offering the same beauty and enduring quality.

From the timeless solitaire — where a single princess-cut diamond sits in a classic four-prong setting — to pavé bands that add extra sparkle, our designs highlight the stone’s radiant shape. For those who love the richness of yellow gold, our gold princess cut engagement rings offer a striking blend of warmth and brilliance.

Shop our range to find your princess cut engagement ring - one that makes you feel like royalty.

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.
