This specimen is listed as a primarily willemite specimen since it is loaded with sharp, hexagonal, prismatic crystals of willemite in many cavities. It also has a 7mm wulfenite that is very sharp but intergrown with oxides at the showy edge. There is another nice willemite crystal but it is loose but captive and rolling around in a different cavity. The willemite crystals are the best feature here since the crystal shape is so good and defined! VERY fluorescent green and purple!
