broche de Napoléon sold by Sotheby's on November 12 for CHF 3.5M, lot 665. Orange.
Asking Grok
Broche de Napoléon sold by Sotheby's on November 12, 2025, sale GE2509, lot 665. What is the estimated creation date for that brooch and the assumptions for who was its jeweler ?
Grok thought :
The brooch, a diamond hat ornament later adapted into a brooch/pendant, has an estimated creation date in the early 19th century . It is assumed to have been crafted by Bernard Marguerite, who served as jeweler to the crown from 1811 to 1815 and had taken over the business of Edme-Marie Foncier (personal jeweler to the Beauharnais family, including Empress Josephine) in 1804. This assumption is based on records of Napoleon's 1805 orders for jewelry, including a ganse and hat button totaling 362,060 francs, with the largest stone (25 carats, paid 180,000 francs) supplied by Marguerite .
