Promote your mineral show on our page !

We offer you the opportunity to list your show for free* in our online calendar. To do so, simply send us the following information by email :


  • Precise location (full address)
  • Event short description
  • Dates and opening hours
  • Entry fees
  • Contact information (website, phone, email)
  • A digital version of the event poster, at least 1024 pixels wide (png, jpeg, webp)

Send your details to contact@le-comptoir-geologique.com, and we will quickly integrate your event into our dedicated page.

Join our initiative to promote mineral fairs and allow an enthusiastic audience to discover your events. Take advantage of this offer—it’s entirely free*!

Your event will appear as shown on the Mineralshows Calendar, and once the event has passed, it will be removed from the listing.

 If your event is canceled, it is your responsibility to inform us without delay. Failure to do so will result in us no longer listing events organized by you.

Please note that we will resize all image files to 1024 pixels wide and convert them to WebP format to ensure smooth and fast display across all digital platforms. Including an image is not mandatory but highly recommended to improve the visibility of your listing. For quality purposes, we do not accept photos or scanned images of printed posters.

   Nota bene

The fact of sending a request does not constitute a reservation of the specimen(s) which can find purchasers in the meantime.
