How to choose from our engagement rings?

So when you browse our collection of lab-created diamond engagement rings, you’ll find lots of ideas, looks and styles to try on and see how they fit your personality and aesthetic. If you’re shopping as a surprise, speak to our team to help match your love to a ring they’ll be sure to love, by booking a virtual consultation.

Which style of lab-made engagement ring is right for you?

We’ve created classic and elegant styles of engagement rings all crafted with genuine diamonds that have been made, not mined. Rings with clean cuts and clean lines, that feature centrally set stones as well as feminine, subtle accent diamonds across the band. By contrast, we’ve also crafted striking, unique styles that play with cut and convention, in wraparound bands and off-centre pear-shaped stones. There is so much to choose from, reflecting the diversity and uniqueness of every woman.

Why buy a lab-grown diamond engagement ring?

As well as a wide range to choose from, you’ll be choosing an ethically-sourced diamond ring set in fully recycled 18 carat gold. Another thing to feel good about as you propose to the one you love. And of course, we offer all of the customisation and personalisation services you would want in choosing such a key piece of jewelry. So whichever style you choose, you’ll be able to set the cut, carat, shape and size of your lab diamond. As well as selecting the right size and colour band it sits within. As well as our customisable service, you can choose to work with our designers to create a unique band from scratch by choosing our bespoke engagement rings service.
