Tamuy and Yves are the most talented, down to earth, and hard working jewellers I’ve had the pleasure of working with. I’ve designed multiple pieces of jewellery and am always in awe of the craftsmanship and experience. Can’t wait to design my next piece
If I could give Tamuy and Yves 10 stars I bloody well would!! They are the kindest and most professional of jewellers and their workmanship, stunning. My fiance are returning customers and can’t ever see ourselves going elsewhere because they are just That good at what they do!
The most commented on piece of jewellery I own!!
I took a sentimental piece of family jewellery in to be redesigned and a month later I am still blown away with the result. The entire process from concept to design and presentation was a first class experience. Tamuy and Yves your artistic professionalism should be celebrated. Thank you so much. I look forward to the next piece, because I will be back.
5 star review honestly falls short
I cannot speak highly enough of Tamuy and Atelier Diamant!
This was a whole new world walking in for a consult around having a ring designed/made and I felt slightly like a fish out of water. Very quickly, Tamuy put me at ease and walked me through the whole process and discussed the different options available. Tamuy had so much wisdom and was able to pull out a design that I couldn’t be more thrilled with, despite me not knowing a whole lot other than most likely only the basics. The designs that were sent through looked incredible and my ring looked even better in person when I went in to pick it up!
Aside from the actual service, Tamuy was incredibly friendly and down to earth and it was an absolute pleasure chatting with her as she helped pull out all the ideas I had scattered in my mind around what I was hoping to have designed.
If you’re in the market for any bespoke jewellery, the team at Atelier Diamant is second to none and I cannot recommend them highly enough!
It’s an absolute pleasure to deal with Tamuy, Yves and the team. A authentic and personable service, which only matches their highly skilled and detail driven approach, in the work they do!

From bold statements to timeless classics, Atelier Diamant represents you.
A truly magnificent ring, featuring three exquisite old European-cut diamonds set across the finger in a singular, beautifully understated setting. Crafted in platinum and 18ct yellow gold, the combination of the antique-cut diamonds and timeless design is simply breathtaking.
There is something incredibly elegant about its simplicity — refined, sophisticated, and effortlessly chic. A rare piece with an old-world glamour that feels both distinctive and utterly timeless.

Rain’s rings.
We’ve had the absolute privilege of creating the most magnificent wedding set for Rain — pairing a beautiful Old European Cut engagement ring with an Old Mine Cut diamond curved wedding band.
Crafted in platinum and 18ct yellow gold, the design beautifully blends antique character with timeless elegance, allowing these exquisite stones to truly shine.
Thank you, Simon, for trusting us with such exceptional stones and for continually pushing our skills, creativity and creative horizons. It’s clients and projects like this that remind us just how grateful we are to do what we love.
A truly radiant and unforgettable set. 💎✨
With the most heartfelt thanks and congratulations!

We gave these antique stones a new life as an articulated fluid pair of earrings, set in platinum—where old-world character meets modern movement. Designed to move with the light.
From another century, reimagined for this one.

This remodel is the kind of piece that stops you in your tracks, the kind that reminds us why we sit at the bench, why we refine, why we chase precision until it becomes instinct. Jenny’s ring has become a capsule of everything we’ve learned, earned, and fought for: skill, talent, and the grit that only years of making can give you.
Built from her diamonds and sapphires, we sourced a marquise of beauty and custom‑cut her sapphires to lock perfectly into this antique‑inspired silhouette. Every stone, every curve, every millimetre is considered. It’s the ultimate remodel, a piece that honours her past while stepping forward with purpose and elegance.
Truly, we couldn’t imagine anyone more deserving of one of the most beautiful rings to leave our studio.

The dreamiest ring we’ve ever seen! We are so in love with this ring. ✨ We had the pleasure of restoring it, resetting five old-mine diamonds and carefully repairing all the settings to perfectly fit the original stones. A truly special piece brought back to life. 💎
