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.
