Engagement Rings

The quality of a diamond is assessed using the 4Cs: cut, colour, clarity and carat weight. These help you understand a diamond's brilliance, appearance and overall characteristics. Selected engagement rings also come with independent diamond certification, giving you added confidence in your choice.

With a heritage rooted in London's renowned Hatton Garden jewellery district, we're committed to exceptional quality and craftsmanship. Our engagement rings are also backed by our jewellery warranty, offering extra peace of mind when choosing a ring to last a lifetime. You can find diamond specifications and certification details on each product page.

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.

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.

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.

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.

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.
