Léon Coulon was a French jeweller, employee of Boucheron until 1879, when he established his own Maison with Jules Debut, formerly a close associate of Fréderic Boucheron. Debut and Coulon produced incredible jewels of exquisite craftsmanship, renowned for their elegant design with innovative techniques. They continued to have international success and were awarded a gold medal at the 1889 Paris World Fair.
Later associated with M. Deverdun, Coulon established L.Coulon et Cie. Both hard-working personalities with great taste and a fantastic eye for beautiful stones, they could not fail to succeed. Their fine and impeccably manufactured jewels flourished.
Léon Coulon was again at the forefront of the 1900 Paris World Fair. Amongst the many remarkable jewels on display was an avant-garde black rose brooch, exhibiting a very similar design to lot 244; as well as an outstanding innovative diamond and aluminium feather brooch. Following the exhibition, Coulon received the prestigious French Legion of Honour.
