The Mineral Vault, with its deep ceilings, brick columns and arches, is a unique space with its own special atmosphere. The museum’s historic architectural structure provides the perfect setting for the gemstone and mineral collection. This presentation is based on the collections of Oldenburger Hans Lüschen and is supplemented by the extensive holdings of the State Museum. Organized by mineralogical groups, the collection offers a comprehensive overview. Intrigued? A selection of colourful and decorative stones is also available in our museum shop.
