About the stamp design: The images on the Minerals stamps were created by Leonard Buckley, a designer at the Bureau of Engraving and Printing. The minerals were photographed by a Smithsonian photographer. The minerals Buckley chose to feature are Azurite, copper, Variscite, and Wulfenite.
First Day City: The First Day of Issue ceremony took place at the Smithsonian’s National Museum of Natural History. Lillian Turner, who had pushed for stamps showing minerals, was an honored guest.
Unusual fact about this stamp: Lillian Turner was the driving force behind these stamps as well as the 1974 Mineral Heritage stamps (#1538-41). She hoped the stamps would publicize the new Hall of Geology, Gems and Minerals at the Smithsonian.
History the stamps represent: Four minerals - azurite, copper, variscite, and wulfenite - were featured on this set of stamps.
Variscite is a rare mineral formed when water rich in phosphate reacts with aluminum rich rocks. It was first discovered in 1837 near a German town then known as Variscia. Its color is similar to turquoise, though usually greener. Variscite has been found in the Western US, including in the states of Utah, Nevada, and Wyoming.
