The copper shist district Mansfeld-Eisleben-Sangerhausen (Saxony-Anhalt) is - among other things - famous for its gypsum specimens. Most collectors know the colorless and grey crystals from Eisleben. From Sangerhausen (Thomas Müntzer shaft) brown elongated crystals are frequent. A certain variety are "Weißkopfgipse" (white-headed gypsum) from that locality - black crystals with colorless tops. There are big samples with crystals standing closely packed: a feast for the eyes! (Author: Andreas Gerstenberg)
