This piece consists of a cut and polished slab of pegmatite that contains several partial Elbaite crystals. These crystals are obviously incomplete, as they have been cut and polished along with the surrounding rock. Their trigonal prismatic form was likely good, as a few crystals show the standard rounded triangular cross-section. The largest sections are mostly red in color, but most of the crystals show the red "core" surrounded by the blue-green "shell" that is indicative of watermelon tourmaline. In their present thickness, they are essentially opaque and are intensely internally-fractured.
