There’s something so special about seeing how each client makes the Living Signet their own.

Some have paired yellow gold with rose gold, some have chosen diamonds, while others have set birthstones into the face, a little piece of their loved ones carried with them.

No two are ever quite the same.

And perhaps that’s what we love most about the Living Signet, watching it become a reflection of the person who wears it and a piece that can continue to grow and evolve with the client🤍

WE JUST MADE DIAMOND HISTORY💎

Tonight, UbyKate unveils not one, but TWO world-first diamond cuts:

The Tri-Cut™ Rose Cut Diamond.
The Tri-Cut™ Portrait Cut Diamond.

Centuries ago, Rose Cut diamonds glowed beneath candlelight, while rare Portrait Cut diamonds protected miniature paintings and precious keepsakes.

We took these two extraordinary vintage cuts, honoured their history, and transformed them through the striking geometry of our signature Tri-Cut™.

Antique soul.
Modern architecture.
Diamonds the world has never seen before. Available exclusively through UbyKate.

Because some diamonds follow history. Others create it.

Stay tuned to see the Portrait cut Diamond xx

There were happy tears in the atelier this week… (and a few were mine!)❤️

I worked with our beautiful client J to take a collection of family stones from pieces that were no longer being worn and turn them into two completely new heirlooms. Pieces that honour where they came from, but feel entirely like her now.

First, the pendant.
We brought together emeralds, sapphires and diamonds from multiple pieces to create this incredibly detailed rose gold pendant, with her largest diamond taking centre stage in a white gold bezel.

My favourite part? We designed it specifically to hang from J’s vintage rose gold fob chain. The moment we put them together, it felt like the pendant had always belonged there.

Then came the ring.
We chose a beautiful feature sapphire, two rubies, two sapphires and two smaller diamonds and created a solid yellow gold Liquid Ring, setting the stones asymmetrically into the gold.

Not symmetrical, but beautifully balanced, something I absolutely love in a piece like this.

When J came into our Kirribilli atelier and we put both pieces on her for the first time, there were tears. Hers. And yes… mine too🥹

There is something incredibly special about taking stones that already carry so much family history and creating pieces that allow those stories to keep being worn.

And the best bit?
J still has more family stones waiting for us.
So I have a feeling this story isn’t quite finished yet. ❤️

What an honour.
