Sphalerite with Galena, Chalcopyrite and Quartz.
A great example of Sphalerite with Galena, Chalcopyrite and Quartz from the 2nd Sovetskii Mine, Russia. The Sphalerite is just superb with high lustre and razor sharp crystallization. It appears as thought the Sphalerite has grown over the Chalcopyrite, which is also well crystallized in some parts. The cube-octahedral crystals of Galena are just exquisite and are highlighted by the interpenetrating twins at the top!
