The   specimen is developed as floater, it consists of two generations - first   generation was responsible for the aesthetic architecture of the piece and is   already in a later stage of alteration. The second generation developed   larger and sharp terminated octahedrons - one larger in the center of the   piece, a second exposed at the top of the specimen. Some of their faces show   a brownish layer, which makes these 2 crystals stand out.
