This specimen consists of a flat, partly-polished slab of tourmalinated quartz, consisting of a white quartz matrix in which are embedded several Elbaite pieces. The Elbaite sections are generally in good condition, though a few are damaged or broken, and measure up to 0.6" (1.5 cm) in diameter. Most of the pieces that are present consist of cross-sections of the trigonal prismatic crystals- these show the standard rounded, triangular shape. Almost all of the pieces are of the variety known as Watermelon Tourmaline, in which a "core" of red or pink material is surrounded by a "skin" of dark green material. They are essentailly opaque and show a pearly luster on the few natural, exposed edges. The quartz host is translucent and cloudy, and shows substantial internal fracturing.
