Stacked skeletal cubes and modified cubo-octahedra forming a curved "monster" of Galena. Remarkable geometric structures in a complex structure. This is mostly Galena but dark Sphalerite and white Quartz are a nice contrasting matrix. Matte metallic luster and slightly melted edges on one side of the specimen with a brighter and sharper display on the opposite side. In fine undamaged condition, this is a far better in person, a striking and unusually esthetic Galena from finds in 2015. A choice modern classic.
