This specimen has orange Wulfenite crystals in a shape that I have never seen before; they are long and prismatic, occuring in a form that reminds me of the elongated four-sided bipyramidal crystals that the mineral anatase often occurs in. Most of the points on the pyramid tips are truncated by small basal faces, but one or two crystals terminate on an edge. They all have a uniform pearly luster and are translucent, and though several crystals are damaged, those that are intact have good crystal form. They rest on a brown limonite matrix that sparkles due to the fact that it is coated with a fine layer of microscopic crystals- I think that they are dolomite, as there are some larger, white crystals of the mineral on part of the specimen. These are some weird little crystals!
