This large thumbnail specimen consists of part of a single Morganite crystal. Even without the considerable breakage that is present, the crystal would not be complete due to the fact that it grew adjacent to the albite/pegmatite host rock and could not form completely, anyway. Thus, the only complete face that is present on this piece is a triangular secondary termination face that truncates the incomplete basal face. There are two smaller tertiary termaination faces adjacent to the secondary, but these are also incomplete. Two extremely thin but complete faces run between the secondary face and the two adjacent prism faces (which are also incomplete), which are in turn separated by another incomplete, thin face. All edges are straight and well-defined and all faces are clean and smooth. The main termination face is the only one that shows a vitreous luster; the rest are surprisingly dull, showing a pearly-to-vitreous luster at best. The surface that was adjacent to the host rock is flat but uneven and is coated with a thin crust that is likely made of albite. The crystal has a pale pink coloration and is transparent and partially clear, though it contains many internal fractures and flaws. There is only a small amount of crystalline albite present on the piece.
