Jean-Marc Tarnaud
J'aime Stone
Meet the Founder
Bonjour, my name is Jean-Marc TARNAUD, and I am « franzose ».
After many years in Germany and an international career that took me to places such as Paris, Frankfurt, Heidelberg, and Dubai—where I lived for four years and led a team of over 30 people—I decided to turn my passion for gemstones and jewelry into my own business. That’s how I founded “J’aime Stone” in 2021.
With nearly 30 years of experience in executive roles in sales, business development, and P&L leadership in the energy and infrastructure sector, I’ve had the opportunity to work in over 60 countries—including Central and Eastern Europe, the “Stan” countries, the Middle East, Israel, and several nations in South Asia.
How did my passion for jewelry and gemstones begin?
It all started with a special encounter: I had the opportunity to acquire the collections and life’s work of an experienced diamond dealer and gemstone & diamond cutter who wanted to pass on his jewellery collections amassed over more than 30 years.
Moreover, my passion is grounded in solid expertise: I am an engineer and geologist with a Master of Science (M.Sc.) in Geosciences, specializing in geology and crystallography. My scientific background allows me to see gemstones not only as works of natural art but also as geological marvels—and to integrate this knowledge into my work.
With J’aime Stone, my mission is to create exceptional pieces of jewellery using natural, untreated gemstones—for people who value authenticity, craftsmanship, and true beauty.
Inside la collection
The fascination with gemstones began with a special encounter: several years ago, I had the opportunity to acquire a collection of natural gemstones as well as the life’s work of a diamond dealer and gemstone cutter who, after more than 30 years of creative jewelry craftsmanship, wished to pass on his knowledge.
My natural gemstones—particularly the rubies—come from depleted deposits in Thai and Burmese mines that have been closed for over 20 years.
With J’aime Stone, I’ve made it my mission to create exceptional jewellery, placing the mineral world and its most noble representatives – natural stones, exclusively – at the heart of each piece

Some testimonials
"Bei großen Juwelieren war ich unsicher, ob die Steine echt und unbehandelt sind. Bei Herrn Tarnaud wusste ich, dass ich echte, hochwertige Edelsteine bekomme – seine Kollektion bietet nicht nur beste Qualität, sondern auch faire Preise. Gemeinsam mit meiner Verlobten haben wir den Ring entworfen – sie wünschte sich einen Saphir mit Diamanten. Ein Modell eines bekannten Juweliers hatte es ihr angetan, und wir haben ein sehr ähnliches Design gewählt – perfekt an die gewünschte Steingröße angepasst. Besonders begeistert hat uns die individuelle Beratung und die Möglichkeit, den Ring ganz nach unseren Vorstellungen anfertigen zu lassen. Perfekte Qualität, volle Transparenz und ein einzigartiges Schmuckstück. Absolut empfehlenswert!"

"Hello, I am Jean-François,
I did not discover "J’Aime Stone" by chance; my mother had previously worked with Mr. Tarnaud’s predecessor, who then put me in touch with him.
The exchanges were quite straightforward. I sent a few pictures of jewellery models that my wife liked. A project was then established with some essential conditions: the stones had to be red [Rubies], preferably Pigeon Blood if possible, and most importantly, natural. J.S. selected the stones accordingly and created two 3D models to help us visualize the designs, presenting us with different alternatives for a final decision.
During the production process, a change in the clasp was requested by my wife, as she preferred a Cartier-style clasp. This request was taken into account in the final creation of the earrings. We even received photos during the production phase. The deadlines were met, allowing me to gift the earrings to my wife on her birthday.
My wife was completely satisfied with the craftsmanship and even more so when her best friend reassured her about the ruby color, confirming that the stones were indeed predominantly Pigeon Blood rubies, which have a red-violet hue rather than bright red.
I am very satisfied with the result and the quality of the work. I am already considering commissioning another piece from "J’Aime Stone", and I will continue to choose natural stones, despite the significant price difference compared to synthetic or treated stones."
Jean-François

"Durch gemeinsame Freunde wurde ich während eines Abends direkt dem Inhaber von „J’aime Stone“ vorgestellt. Wir konnten uns kurz zurückziehen, sodaß ich ihm persönlich erklären konnte, wie ich mir meinen Ring vorstellte. Ich möchte anmerken, dass ich zuvor keinerlei Schmuck getragen hatte.
Unter Berücksichtigung meiner Wünsche – und mit Hilfe einiger Fotos von Modellen, in die ich mich auf den ersten Blick verliebt hatte – wurde mir ein 3D-Modell vorgeschlagen, das all die Elemente vereinte, die ich mir für meinen Ring wünschte. Nachdem ich das Modell bestätigt hatte, zeigte mir Herr Tarnaud mehrere natürliche Edelsteine aus seiner Kollektion – alle in Tropfenform und von identischer Größe: grüne, blaue und rote Steine (wobei mir Letztere etwas weniger zusagten). Nachdem ich mich für einen Stein entschieden hatte, legten wir auch das Metall fest: 18k Gelbgold.
Zufrieden mit der Qualität der Arbeit und der Auswahl an Edelsteinen, gönnte ich mir einen zweiten Ring – und plane nun, einen dritten anfertigen zu lassen, den ich meiner Schwester zu ihrem 40. Geburtstag schenken möchte."
