This small thumbnail specimen consists of a single hexagonal Goshenite crystal. It is in excellent condition, showing almost no damage, and has a well-defined, almost tabular crystal form. Most of its edges are well-defined, but there are a few whose formation was spoiled due to some intersecting albite blades. Their faces are generally smooth, though one or two are pockmarked from intersecting albite or muscovite books that were since worn away. Both basal termination faces (yes, it is double-terminated) and all of the prism faces have a glassy, vitreous luster, and the secondary termination faces have a primarily matte luster. The crystal is colorless and transparent, though there is not very much clear material within; it has many small internal fractures, flaws, and inclusions. It is, however, a good crystalline example of beryl.
