Harzer Mineralien-und Fossilienbörse Clausthal-Zellerfeld

The Harz Mineral and Fossil Fair is a long-established trade and public exhibition that transforms the Stadthalle in Clausthal-Zellerfeld into a vibrant center of geological diversity every autumn. Organized by the Montangeological Association Harz (Montangeologischer Verein Harz e. V.), the fair has, for many years, brought together collectors, dealers, scientists, and enthusiasts of the geosciences from across the German-speaking world. It is a firmly established date in the calendar of the scene – notable for its unique combination of regional heritage and international offerings.

At the heart of the fair are carefully curated mineral specimens from around the globe – including crystals with extraordinary growth forms, rare mineral clusters, and scientifically significant pieces. This selection is complemented by a wide array of impressive fossils that fascinate not only collectors but also serve as tangible records of Earth’s history. A particular focus is placed on the geological heritage of the Harz Mountains: regional rocks and ores, both scientifically and historically important, give the fair its distinctive character. This local grounding highlights the event’s educational and museum-quality standards.

A broad range of exhibitors showcases not only minerals and fossils, but also unique jewelry crafted from natural materials and artisanally processed one-of-a-kind items. The fair is far more than a marketplace: it is also an exhibition space, a knowledge hub, and a meeting point for the geoscience community.

Scientific exchange plays a central role. Geologists, collectors, amateur researchers, school groups, and educational institutions use the fair as an opportunity to learn about recent discoveries, new sites, and current scientific developments. The consistently high level of these conversations has become a hallmark of the event.

The audience includes professionals from geology, mineralogy, paleontology, museology, education, and artisan jewelry design. Families and school classes are also regular visitors, thanks to the fair’s engaging and well-structured presentation of its content.

Clausthal-Zellerfeld is not only the geological heart of the Harz region but also a place of academic tradition. The Clausthal University of Technology, with its long-standing expertise in the geosciences, adds a special dimension to the fair’s atmosphere.

The Stadthalle is centrally located and easily accessible by car or public transport. Nestled in the picturesque landscape of the Upper Harz, it provides an ideal setting for a highly specialized event that unites natural sciences, regional history, and aesthetic appreciation. The Harz Mineral and Fossil Fair is a must-attend for anyone with a passion for the treasures of the Earth.

The Harzer Mineralien-und Fossilienbörse will take place on 2 days from Saturday, 27. September to Sunday, 28. September 2025 in Clausthal-Zellerfeld.
