The Jouy-en-Josas Geological Association invites you to the 49th International Mineral, Fossil and Jewellery Fair, which it is organising on 29 and 30 November 2025 at the Théâtre du Vieux Marché, Place de la Marne in Jouy-en-Josas.
Around forty French and international exhibitors will present their collections of minerals, fossils, cut stones and designer jewellery. You will be able to purchase items that will delight collectors and those looking for beautiful pieces to display or give as gifts, not to mention younger visitors.
- Activities and games for young visitors will be held every afternoon during the fair in the form of quiz games, where they can try to win mineralogical prizes.
- Small mineralogical welcome gifts will be distributed to young visitors at the entrance.
- Raffle tickets (€1), valid for all draws taking place on the afternoons of the two days of the exhibition, will offer visitors the chance to win a mineral prize to add to their collections.
A bar and fast food will be available.
Access: The Transilien V line (formerly RER C) serves Jouy en Josas station, as do numerous bus routes. All information is available at https://me-deplacer.iledefrance-mobilites.fr/fiches-horaires/bus
