At least 20 rounded Ankerite blades make up the bulk of this specimen. Though at least half of them are damaged or broken, those that are complete show an excellent and very delicate form. The largest crystal has a diameter of nearly 0.5" (1.3 cm) and like the others, possesses very sharp edges and finely but intensely striated faces that give it a silky luster. All of the crystals have a cream coloration and a milky consistency that renders them only dimly transparent along their edges. This effect is also aided by the presence of some internal fractures that lie within most of the crystals. Among the Ankerites rests a single hexagonal prismatic quartz crystal that is colorless and has excellent form. It is transparent and very clear in the upper two-thirds of its length. Below that, it shows intense cloudiness due to inclusions. All of this rests on a base that consists mostly of broken, intergrown Ankerites. However, there are a few other bits of material present; a dull brown material provides a thin shelf on which the quartz crystal rests. I think that it may be siderite. There are also a few tiny smatterings of a green material present. Judging from its softness and its luster, I am guessing that it is made up of fuchsite or some other mica-related mineral.
