Jérôme Bonneville's story is that of a passionate designer, fascinated by precious stones from an early age.
Born into a family of artists and craftsmen - his father a gourmet chef and his brother a perfume designer - he grew up in a world where rigour, artistic sensitivity and the quest for perfection were essential.
He began collecting stones at an early age, marvelling at their colours and uniqueness. This curiosity naturally led him to turn his passion into a profession.
To master the science of gemstones, Jérôme trained at the Antwerp Gemmological Institute (HRD), one of the most renowned centres in the world.
He obtained his diploma in gemmology (Graduate Gemmologist), specialising in the study of diamonds and coloured stones.
This rigorous scientific knowledge enables him to know each gem with precision and to guide his customers in their choice of each precious stone.
Jérome Bonneville is Meilleur Ouvrier de France (MOF), This is the ultimate accolade for craftsmanship.
This title, awarded following an exceptionally demanding competition, rewards technical mastery, creativity and the ability to achieve a level of perfection recognised at the highest level.
To be a MOF is to belong to a worldwide elite of craftsmen who perpetuate French excellence in the arts and crafts. It is also official recognition of rare expertise and outstanding creativity.
By setting up in Lausanne and Zurich, Jérôme Bonneville is bringing this unique label of excellence to Switzerland, a guarantee of confidence and prestige for his customers.
Always driven by the search for exceptional gems, Jérôme travels the world, from Asia to East Africa.
These trips have enabled it to gain direct access to mines and dealers, to select stones at source, and to build up a trusted international network over more than 20 years.
Each gem chosen is the result of a meticulous meeting and selection process. Whether diamonds, rubies, sapphires, emeralds or other rare stones, all are rigorously selected to the highest standards.
