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.

There are big samples with crystals standing closely packed: a feast for the eyes! (Author: Andreas Gerstenberg)
