Selected
specimens from the U.S. National Museum (Smithsonian)
| Enjoy this exciting
selection of original specimens from this renowned source. Through active trading in the Sixties and Seventies, we provided the U.S. National Museum with several important specimens and got many exciting minerals in return. Several of the specimens below originate from even older collections, e.g. the Bosch Collection, and carry dates as old as the 1890s. |
