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.

Unique Platinum Diamond 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’.

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 unique 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.

When you find the love of your life, you know there’s nothing else like it on earth. Unmatched and one of a kind, the bond you share is unique in ways known only to the two of you—so why not choose a unique platinum engagement ring that feels the same? Our unique engagement ring designs celebrate the original and unexpected through diamond clusters, asymmetrical designs, and pavé styles like you’ve never seen before. Far from trendy, these handcrafted rings take timeless designs and turn them into something that’s uniquely yours.
