Description
A fairly dense deep blue color mass of crystalized Posnjakite from Spania Dolina. This ancient Copper mine has been worked for over 1000 years and probably even in the Neolithic era. At times known as Herrungrund (German periods often seen on old labels). This deposit is very large and has many old mines along a belt of several kilometers. This zone has produced a number of colorful Copper species along the oxidized zone of the deposit. Thgis is a choice specimen for the area.
