This large hand specimen consists of a chunk of pegmatite in which are embedded several broken and incomplete Elbaite crystals. Due to their lack of completeness and partial exposure, their trigonal form is evident but quite poor in most areas. Both the intact and broken faces show a vitreous luster, and though some of the smaller crystals are purely dark green in color, the larger ones tend to be watermelon tourmalines, consisting of a dark green "shell" of material that surrounds a red "core". All are essentially opaque due to intense internal fracturing, though portions are translucent or even transparent.
