The original Keystone silhouette, reimagined with four bezel-set diamonds across its sculptural gold face. Featuring UbyKate’s proprietary Tri-Cut alongside pear, oval and round-cut lab-grown diamonds, each stone brings its own brilliance and character to the design.

A generous gold dome and crisp central ridge create the signature Keystone profile, while four individually bezel-set diamonds introduce a considered balance of bold gold and light. The result is a substantial diamond ring with a strong architectural presence and plenty of room for its own meaning.

The Keystone started with four diamonds, each representing one member of a family.

From there, the idea became something bigger. Four stones set confidently across the face of the ring create a strong, graphic silhouette that feels just as good worn simply for the love of diamonds.

The four stones can represent whatever you want them to. People, places, milestones, chapters, lucky numbers or nothing at all.

The name Keystone references the architectural stone that holds an arch together, a nod to the idea of separate pieces becoming one considered whole.

As each piece is custom made especially for you, bespoke and made-to-order jewellery is not eligible for exchange or return.

A Note From Kate

Twenty four years ago I was encouraged to follow my passion and create the jewellery range of my dreams.

We are a multi-generational family run small business, pouring heart and soul into handcrafting and designing heirloom-quality pieces U and your loved ones will cherish for years to come.

Our in-house manufacturing gives us greater freedom and flexibility to work with our community of customers, listen to feedback and deliver customer jewellery requests in real-time.

I have loved every minute of creating beautiful jewellery for U. Pouring my passion into each piece and watching it come to life is deeply satisfying, with each piece always inspiring me with ideas for the next new creation.
