 Napoleon's exile caused Nitot, a fervent royalist, to withdraw from the jewellery house, selling the business to his foreman, Jean Baptiste Fossin (1786–1848).Assisted by his son Jules (1808–1869), Fossin elegantly interpreted romantic jewellery pieces inspired by the arts of the Italian Renaissance and the French 18th century, but also naturalist-themed pieces.The elite of the period were won over and the family of Louis-Philippe, King of France from 1830 to 1848, as well as the Duchesse de Berry, succeeded Napoleon on the list of famous clients of what was to become Chaumet.
