This large hand specimen consists of a chunk of pegmatite in which are embedded at least 10 portions of large Elbaite "Watermelon Tourmaline" crystals. These crystals are all badly broken and mostly incomplete, but have good trigonal prismatic form where it can be determined. All show a dull pearly to waxy luster where they are broken, but possess a brighter, pearly luster where intact. All are generally alike in color, containing a pink "core" that is surrounded by a green "skin" of Elbaite. The pegmatite host in which they rest is made up mostly of quartz, but there is a small amount of elbaite present.
