Riondet offers a wide range of antique jewelry from the main artistic movements of the 18th to the 20th century (jewelry from the two Empires, Art Nouveau, Art Deco…). Its key words are authenticity and rarity. This singular requirement leads her to present a selection without any jewel resulting from a standardized production, nor any re-edition.

In addition, a selection of signed jewelry (Van Cleef & Arpels, Cartier, Boucheron, Chaumet…).
