An absolute knockout of a piece, the Pyrite octahedrons on here are stellar. Sharp, lustrous, and with modified tips, they range up to 2.3 cm on edge. The pics tell the story here of just how aesthetic this cabinet piece is. It is NOT another one of the "usual sort" of pyrites which come out by the ton. Art Soregaroli edited the magnum opus book on Peru mineral specimens, and this is from his prized collection of miniatures and small cabinet sized Peru pieces, most of which he obtained himself down there in the 1980s and 1990s.
