How do you figure out you or your partner's ring size?

You’ve decided to pop the question and take the first step to spending the rest of your life together, but what ring size is my partner?! We have some invaluable advice for choosing that perfect ring available on our ring size guide – even if you’re planning a surprise proposal.

Do we get inspired by celebrity engagement rings?

Engagement rings are so special because they’re more than just a jewellery purchase. They’re a tangible mark of the intention to get married, while a wedding ring symbolises the union. We understand how sentimentally valuable an engagement is and we love that this symbol of commitment can be so personal to each couple. As designers, we’ve always looked to the high-profile jewellery of celebrities, royals, and cultural icons to kickstart our creativity. And lots of our customers feel the same! Browse through our collection of celebrity engagement ring guides to how you can incorporate some new ideas into a design that suits your price point. Additionally, we’ve collected some of the most popular bespoke designs from our Instagram page into one place so that you can get the design ideas flowing.

18ct White Gold Oval Diamond Gemstone Sides Engagement Rings

We want the process of finding a ring to be a creative act, one that gets to the heart of what makes your love unique. Our collection of engagement rings features a diverse range of styles, metals, and ring shapes, making it easy for you to feel confident that you’ve found ‘the one’.

White gold engagement rings are second to none when it comes to classic romance. Refined and bright, gemstone sides engagement rings look their best set in white gold as this precious metal can bring light and detail to each handcrafted design feature. Ideal for intricate metal work such as milgrain and filigree, 18ct white gold is perfect for the romantics at heart.

Engagement rings with colourful side gemstones are the perfect way to make a ring design truly yours. With a spectrum of dazzling hues and shapes, it’s no wonder there’s a white gold colourful side gemstone design to capture every love story. Choose a design that features your partner’s birthstone or their favourite colour to symbolise the colour of your love.

The second most popular diamond shape for gemstone sides engagement rings is the oval diamond. We adore the way this shape brings all of the curving lines and internal fire of a round diamond, while still offering something unique. Our curated selection of oval diamond gemstone sides engagement rings are especially flattering as the elongated shape of the oval diamond moves with the natural line and curve of your hand.
