Clausthalite with Calcite

ID: CC28065
Clausthalite is a very rare lead selenide with the simple yet elegant chemistry of PbSe.  The Clausthalite occurs as a dark grey, fine granular impregnation in white cryptocrystalline Calcite overlying a lower half of brick red massive Calcite.  Although there are no Clausthalite crystals, there does appear to be several tiny crystal faces scattered throughout the granular druse.  This small cabinet specimen is from Brummerjan mine in Saxony, Germany and is accompanied with two very old looking labels written in German.  It has to be said one label is in the most beautiful and precise copperplate handwriting one could ever wish to see.
