Eisenkiesel quartz covered with hematite crystals, calcite, dolomite and siderite. Classic find (1920s) from Abraham shaft, Himmelfahrt mine, Freiberg, Saxony. Sample width: 7 cm. Although being "simple" gangue minerals good samples from Himmelfahrt mine (central Freiberg district) are as hard to find as good silver minerals from Freiberg. Especially in the case of district rarities as hematite xls. (Author: Andreas Gerstenberg)
