The expertise behind the masterclass
François Deprez is a precious stone dealer and the founder of Bonnot Paris, a fine jewellery house specialising in exceptional gemstones.
Known as the French Gem Hunter, he has spent years travelling the world's great trading centres — Bangkok, Jaipur, Sri Lanka — to source the finest stones directly.
He built his path entirely on his own, forging a trusted international network step by step. After launching a first company in B2B stone trading, he founded Bonnot Paris with a clear vision: to open up access to quality gemstones and offer a genuine alternative to the established traditional circuits.
His dual perspective — that of a hands-on stone dealer and that of a luxury brand creator — allows him to share a singular expertise: understanding market flows, buying with precision, avoiding costly mistakes, and turning a passion into a lasting endeavour.
François is a member of the ICA, the International Colored Gemstone Association.
