Princess Cut Diamond and Gemstone Engagement Rings

Our princess cut engagement rings come in a range of designs - they span solitaire, halo, pavé, and side-stone styles in 9k and 18k white and yellow gold, platinum, and sterling silver. The princess cut is defined by its square silhouette and brilliant-cut facet pattern, a shape that delivers exceptional light return and a geometric precision that suits both classic and contemporary settings equally well. The square outline makes a princess cut diamond appear bold and architectural in a four-prong solitaire, while in a halo or pavé setting the same shape becomes the anchor for something more elaborate. For those drawn to colour, the collection also includes square diamond engagement rings set alongside sapphire, emerald, and ruby, where the princess cut's clean lines draw out the depth of the gemstone.

Every ring is consciously crafted from recycled precious metals. Diamond rings are set with conflict-free natural diamonds, ethically sourced in line with the UN-backed Kimberley Process, or sustainably created lab-grown diamonds - chemically and visually identical to natural stones and equal in brilliance, beauty, and quality. Gemstone pieces feature stones handpicked for their colour and clarity. Each piece is designed and handcrafted in Britain with 70 years of fine jewellery expertise.

FAQs

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 or contact our customer service team.

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.
