Our story
From the Jura to rue de la Paix
From his childhood in the Jura, the cradle of gemstone cutting in the early twentieth century, François Deprez was captivated by the art of the lapidary.
01 — A childhood in the Jura
From his childhood in the Jura, the cradle of gemstone cutting in the early twentieth century, François Deprez was captivated by the art of the lapidary.
02 — Trading precious stones
His proximity to Geneva deepened this passion: at the age of 7, he discovered the famous Rue du Rhône and its renowned jewellers. That experience kindled in him an enduring desire to become a dealer and found his own jewellery house.
03 — The jewelry house
Founded by François Deprez, a renowned expert in the field of precious stones, our house is distinguished by its commitment to quality, authenticity and singularity.

Our philosophy
Our philosophy
The philosophy of Maison Bonnot Paris rests on three fundamental pillars: Excellence, Authenticity and Singularity.
Excellence
We believe in excellence — not only in our precious stones, but in everything we do. Each gem is carefully selected and every piece of jewellery is conceived with meticulous attention to detail.
Authenticity
At Bonnot Paris, authenticity is an absolute standard. Each of our precious stones is rigorously selected at source, accompanied by its certificates of origin and chosen for the integrity of its story as much as for the brilliance of its fire. We refuse compromise and uphold transparency at every step, from mine to setting.
Singularity
We believe that an exceptional piece of jewellery should be as unique as the person who wears it. At Bonnot Paris, every creation is conceived as a singular work, designed to reveal the character of a rare stone and the spirit of the one for whom it is destined. Far from standardised production, each piece is born from an intimate dialogue between our stone dealers, our partners and our clients. It is this pursuit of the bespoke and the inimitable that makes every Bonnot piece a signature unto itself.
Certification by partner laboratories
At Bonnot Paris, every precious stone passes through our certification laboratory.
Through rigorous analysis and state-of-the-art equipment, we guarantee the authenticity, purity and quality of our gemstones. Each stone is accompanied by a certificate of authenticity issued by our experts, ensuring our clients complete transparency and absolute confidence in their investment.
Contact usFAQ
Every Bonnot Paris piece is designed in Paris and brought to life in France, Italy or Bangkok, in keeping with the codes of French haute joaillerie. From the first sketch to the final setting, each stage is overseen to ensure an irreproachable standard of quality.
Our stones are selected directly through our offices in India, Bangkok and Sri Lanka. We work with trusted partners, upholding the highest standards of traceability and ethical sourcing. Each gemstone is accompanied by an authenticity certificate issued by an independent, recognised gemmological laboratory.
