The author’s museum is a result of the passion of the owners Ewa and Dariusz Siemoński. It’s one of the largest and most beautiful museums of this type in Poland. More than 1000 mineral specimens, precious stones and fossils displayed in 6 exhibition rooms on over 200 square meters of surface.
All specimens in the collection are of high quality. Mostly shown in its natural forms in the matrix, but not only. Among them there are also polished stones, faceted, cabochons, sculptures and in jewelry.
A lot of tables, descriptions and images were placed at the exhibition to help you explore the world of minerals.
Tourists can also count on the expertise and professional information from two guides and service of the museum shop.
The exhibits come from all over the world and are grouped according to crystallochemical classification. The most represented group are the ones that are most common in nature, i.e. oxides and silicates. Among them, the quartz variety is topped with a 100-kilogram twinned  Arkansas rock crystal (probably the largest one to see in Poland) and a large, half-meter-long plasters and geodes of agates, amethysts and brazilian citrines (among them a specimen weighing about 400 kg). You can also see a lot of rare and precious minerals like more than 3 carat diamond crystal, colorful varieties of corundum (rubies and sapphires), beryls, spinels, tourmalines, garnets and more common feldspar or Indian zeolites with fascinating forms and colors. Mineralogists will find here also extremely rare minerals such as crocoit, cornetite, neptunite, benitoit or fluorocanilonite and many other curiosities.
Minerals from the world are prominent in the collections, but we have also many polish specimens, in particular those from the Świętokrzyskie Mountains, among them varicites and wavellites from Wiśniówka, various specimens of calcite, aragonite, malachite from Miedzianka, jet or our regional – striped flint. The museum has a unique collection of this stone.
The fossils represent a smaller part of the exhibition but equally impressive. The trilobite collection (3-30cm long), nautilidae (7-100cm long) and pyrite ammonites Speetoniceras versicolor 40cm-diameter from Russia, as well as natural dinosaurs bones from the group of sauropods (Tazoudazaura). Every year the owners buy new specimens, for example, recently a collection of Polish ammonites from the legendary location of Łuków and a very rare specimen of a beautiful barite from a non-existing Stanisławów location, as well as sculptures from Chinese jade. Information about new specimens can be read on the blog or facebook.
