Description
An attractive combination of Galena cubes and octahedrons with partial step-like textures. The sharp, steel-gray crystals have a dull metallic luster. Some faces are adorned with tiny black Sphalerite crystals and brass-colored Marcasite "Sperkise" which is a specific kind of "spearhead"-shaped twin on the {101} face. The term is a historic mining term used by German miners. The specimen shows no contact, it is perfect all around.
