Beautiful minerals of the GDR The Ministry of Posts and Telecommunications of the GDR publishes a series with six multicolored special postage stamps on which beautiful minerals from the German Democratic Republic are depicted. Minerals of the GDR Many types and varieties of minerals have been described in the scientific literature for the first time in the Ore Mountains, the Thuringian Forest and the Harz. A large number of minerals occur in the territory of the German Democratic Republic in excellent quality and special beauty. For these reasons, minerals of our homeland can be found in all the major collections in the world. As in recent years again and again interesting findings of minerals were discovered in the GDR, the issue of a stamp series with mineral motifs is of particular relevance. The minerals displayed on the stamps were all found on the territory of the GDR today. The steps are stored in the mineralogical collection of the Geosciences section of the Bergakademie Freiberg. 10 Pfennig Value: Fluorite (fluorspar) CaF2, Grube Aid, Halsbrücke near Freiberg (Saxony) (No. 56 658) Fluorite is a widely used mineral that stands out for its expressive colors and high gloss of glass. Yellow, green, purple, pink and blue shades are to be found in a variety of nuances. As a rule, the fluorite crystallizes in well-formed cubes. The step shown on the stamp has a size of about 65 x 60 mm, the large area of the cube is 40 x 40 mm. The ink blue color of the crystals is extremely typical of fluorites from the neck bridge and does not occur with this color on other deposits. The illustrated minerals give a little insight into the richness and beauty of the mineral deposits of the GDR. The exhibitions of the mineralogical collections at the Bergakademie in Freiberg (Saxony) and the Humboldt University in Berlin provide a much broader overview of this area of nature.
