Arborescent and herringbone crystallization of Safflorite in 4cm rods suspended in matrix. Nickeline has replaced some of the cores of the Safflorite rods.  Truly an amazing specimen with interesting ore genesis and great for ore microscopy. The face is sawed flat. The flip side is natural and rough.
