 This aim came to fruition with the creation of a museum in 1980 under the impetus of Béatrice de Plinval.The museum's archives contain 200 items of jewellery, 19,800 original invoices, 80,000 drawings, 2,500 diadems and replicas of diadems in nickel silver – hundreds of which have been created since 1780.The museum is not open to the public but regularly organises events or exhibitions based on its collections.
