FERBERITE, QUARTZ, TOPAZ, ARSENOPYRITE, MUSCOVITE

In this specimen we can enjoy several hyaline quartz crystals, with an excellent transparence, brilliance and very well-defined faces and edges. We could say that they form the matrix of some tabular ferberite crystals, very well-defined and of an intense black color. Along with these two species we can observe numerous crystals of topaz, very transparent, brilliant and well-faceted. They are accompanied by arsenopyrite and muscovite.
