Benoît Charbonneau

Trained as a jeweler and gemologist at GIA, Benoît invites you to discover his passion for gemstones. Fascinated by stones since his childhood, he never ceases to carry you away in his world of colors and unique journeys.

With more than 20 years of experience in jewelry and gemology, as a trader for the most exclusives jewelers at Place Vendôme in Paris and with artisan jewelers between Asia and France, he puts all of his trading experience and expertise at your service


Gemology was an integral part of Benoît Charbonneau’s education, at the end of 6 years of jewellery studies. After obtaining his graduation and winning several awards in jewellery, the young gemologist first worked as a jeweller in the prestigious workshops of the Place Vendôme in Paris, then for the famous jeweller "Chopard" in St Barths during 6 years. Before its return to France, he spent 6 months at the GIA (Gemological Institute of America) in the United States to perfect his technical expertise in gemology.

After his experience in St Barths with an elite clientele, this jeweller-gemologist settled in France, and several positions in the jewellery business, Benoît Charbonneau's experience, knowledge and personality found an effective way to express itself by specialising in the trade and opening his company GEM SELECTION in 2015 in France.
