Portions of several Elbaite Watermelon Tourmaline crystals are embedded in the pegmatite matrix of this hand specimen. These pieces are heavily weathered and broken and are all incomplete. Their trigonal prismatic forms are almost indeterminate, and their luster is dulled by the breakage and wear. Almost all of them consist of a "core" of pink material that is surrounded by a dark green "skin", but one piece appears to be solid green in coloration. They are all effectively opaque due to their intense internal fracturing. Their pegmatite host is made up mostly of quartz, but there is a substantial amount of albite present, which contains quite a bit of muscovite.
