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.

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’.

When it comes to engagement rings, platinum has always been the most popular choice—accounting for over 60% of the rings we make today. Durable, naturally bright, and low maintenance, this precious metal makes platinum engagement rings last a lifetime. A platinum band with a unique ring is a match made in heaven, sure to make any centre diamond look its best for years to come.

Radiant diamonds are loved for their symmetry and internal fire, having been developed by combining an emerald cut diamond with a round cut. Our range of {{metal_type}} radiant diamond engagement rings have all been designed to best showcase this uncommon diamond shape, resulting in rings that look unlike any other. Because of their rectangular shape and brilliant facet structure, a radiant diamond engagement ring is the way to go for someone who doesn’t want to compromise on sparkle.
