Wulfenite in its Bipyramidal crystal habit on contrasting green Mimetite. Mineralization all around! Some Wulfenite crystals are truncated cubes, some terminate sharply. The deep internal space is both protective of the crystals inside and open from multiple sides for some amazing lighting opportunities. Unique and endlessly explorable!
