Description
A specimen with the Lead-Arsenic sulfosalt Jordanite, steel-gray in color and with a strong metallic luster. The rare species is embedded in layers of Schalenblende, which is by definition alternating layers of Galena, Sphalerite and Wurtzite. Included are two historic labels in German language which state that the specimen was obtained on May 4, 1933 from engineer Helmut Steck. Very classic polish material!
