In the organizer's words:

Sparkling gemstones, mysterious rocks from outer space and minerals found in smartphones - all this and much more will be the focus when Dr. Stefan Peters, Head of Mineralogy, reads from his new book "WAS IST WAS: Minerals and Rocks - Treasures of Nature". Short reading passages and a lively lecture will provide insights into the formation of minerals, the diversity of rocks and the special features of rare raw materials.

Afterwards, books will be signed, finds will be examined by experts and minerals and rocks from the book will be presented in more detail at information stations. The afternoon also offers the opportunity to find out more, try things out and discover the mineral world of the museum. The end is open, so that the urge to discover can be lived out extensively.

With exciting stories, impressive pictures and many moments of discovery, this event shows the fascinating world of minerals and rocks in all their diversity. Free admission.
