Although the Mineralogical Museum was founded with the gift of the collection of Irenee du Pont, Sr., it has grown to encompass specimens gifted or made possible by many generous donors, including Mrs. David Craven, Alvin B. Stiles and Frederick Keidel. Because of our intimate space, we have chosen to focus on individual displays that illustrate particular mineralogical concepts or themes. These include gem minerals from the du Pont collection mined in the early 20th century, as well as more recent finds of minerals from North America. Newly installed display cabinets with fiber optic lighting provide accurate color balance for specimens from the wire silvers to the vivid orange wulfenites.
