Bespoke Yellow Gold Signet Ring in Nantes: A Napoleon 20-Franc Coin

At the start of my career, every request for a transformation filled me with keen curiosity and an almost excessive desire to do things well. The years have passed, and that feeling has never left me. I found it intact the day a client walked into my workshop in Saint-Sébastien-sur-Loire, near Nantes, with a Napoleon 20-franc coin in the hollow of his hand.

A meeting over a Napoleon 20-franc coin

He did not put it down on the counter straight away. He held it for a moment first, the way one hesitates before entrusting something that matters. Then he explained his idea: he wanted this coin to become a signet ring. He was not looking for a showcase piece, but for an object that would carry the weight of history while bearing a personal touch.

I took the coin, turned it under the light, and sensed its potential. The emperor's profile, the relief of the metal, that discreet patina: all of it deserved better than a drawer. A Napoleon 20-franc coin signet ring is anything but an ordinary commission. It calls for balance, because the jewel must enhance the coin without ever betraying it.

Gold brought by the client, full of memories

My client had also brought his own gold. It is a gesture I always receive with a certain respect. Gold entrusted to a jeweller is never simply metal: it is a silent witness, one that has been through happy or difficult moments in the life of its owner.

So we spoke about the project in low voices, almost with modesty. The idea was a beautiful one: to unite two pieces of history, the emblematic coin and this personal gold, in a single jewel. For me, it was a challenge I was more than happy to take on, and the promise of a bespoke yellow gold signet ring in Nantes that would truly resemble the person who wore it.

From casting to closed setting: making the signet ring

Melting the gold to give it a new form

I began by melting the gold my client had brought. When metal turns liquid, something happens that I have never ceased to admire: it flows slowly, gleaming, almost alive. Each time, I think of those who owned it before him. Once the gold was ready and purified by the flame, I worked on the base of the signet ring.

This base had to be robust. A coin has volume and presence, and the band that holds it must carry it for years without tiring. I therefore forged the body of the ring with care, constantly checking its seat, its hold and its comfort on the hand.

The closed setting, a work of patience

Then came the most delicate stage: the closed setting. Setting a coin in a closed mount is no small matter. One must create a sturdy and elegant bezel that holds the 20-franc coin firmly without crushing it and without hiding it. The metal surrounds the coin around its entire circumference, and that is precisely what makes the exercise so demanding.

Here, every millimetre counts. An angle too closed, and the coin is smothered. An angle too open, and it no longer holds. I proceeded slowly, going back, adjusting, looking closely and then from a distance. After hours of meticulous work, the coin finally found its place, firm and true, in its gold housing.

Polishing to reveal the yellow gold

Polishing remained. This is the moment when the yellow gold takes on its warm light, when the surfaces soften and the edges melt into the overall line of the jewel. I took care not to erase the relief of the coin: Napoleon had to keep his character, and the metal of the band had to frame him frankly, without masking him.

A signet ring between past and present

When I placed the finished signet ring under the lamp on my bench, I stayed a while simply looking at it. The glow of the gold and the majesty of the emperor answered one another, as if each had always been made for the other. I felt a deep satisfaction, the kind one feels when the craftsman's hand disappears behind the obviousness of the object.

What I love about this kind of commission is that it links different eras. On one side, a coin struck long ago, which has passed from hand to hand. On the other, personal gold, melted in my workshop and reshaped for today. Together they form a jewel which, I hope, will be cherished and handed down to generations to come.

This story also shows what bespoke work makes possible: to transform a coin into a jewel while respecting both the original metal and the person who will wear it. It is not a matter of applying a template, but of listening, designing, then building piece by piece, gesture by gesture.

Come and talk about it at the workshop

If you keep an old coin at home, a piece of gold you no longer know what to do with, or simply a wish for a signet ring that suits you, you are most welcome at my workshop in Saint-Sébastien-sur-Loire, near Nantes. Bring what you have, even if the idea is still vague: we will take the time to talk it through, quietly, at the workbench.
