Exhibition - The Pink Diamond
From October 17, 2026, to January 3, 2027, the Condé Museum at the Château de Chantilly, in partnership with L’École des Arts Joailliers, is presenting an exhibition tracing the history of a legendary historical diamond: The Pink Diamond.
Known as the “Grand Condé,” the Pink Diamond is a historic stone weighing over 9 carats, documented in the collections of the Princes of Condé since the 18th century. This jewel, renowned for its exceptional color and provenance, was stolen in October 1926 but recovered shortly thereafter, hidden inside an apple.
A century later, the Pink Diamond is once again on public display as part of this special exhibition. To mark the occasion, the Musée Condé and L’École des Arts Joailliers have undertaken an extensive interdisciplinary research project—the first of its kind for a diamond of this caliber. Thanks to wide-ranging gemmological and historical analyses, all of its secrets are now being revealed.

Visit this exhibition in the Gallery of Psyché and the Gem Room. Explore these two spaces dedicated to art and collections.
In partnership with L’ÉCOLE, School of Jewelry Arts, supported by Van Cleef & Arpels
With the support of GRoW @ Annenberg Foundation and the Friends of the Domaine de Chantilly.
