A significant specimen of the rare silver mineral, Stephanite. This RAZOR SHARP cluster is composed of lustrous hexagonal crystals up to 1 cm in length. Such good crystallization and definition is uncommon, and these crystals are even slightly hoppered for added geometric complexity. An important and aesthetic thumbnail that is competition quality and would fit in any top collection. It is fullsized, 3-dimensional, and imposing visually in person. One of my favorites in the collection!
