This large hand specimen is composed of orange and yellow crystals of orpiment, coating both sides of a plate of a black host rock. While the crystals are intergrown and incomplete, there are several large ones, including a book of flat crystals with a clean face. The color and luster of this specimen is quite good, although most of the exposed surfaces are fracture, and only a few crystals have natural terminations. The specimen has a crack that nearly penetrates it, and I suspect that some flexible crystals of orpiment are the glue that holds it together. Likewise, the nice large crystal (see the closeup image) is also somewhat loose, so care should be taken when handling this specimen.
