Several Elbaite crystals permeate the pegmatite host rock of this small cabinet specimen. These crystals are difficult to measure and effectively study, as those parts that are exposed are either damaged and broken or heavily worn. Many have definite trigonal prismatic form, however, with either 3- or 6-sided cross-sections. Their luster is dull where broken, but a moderate to dull pearly where intact. Most have the classic "watermelon" coloration, in which a red "core" of material is surrounded by a dark green "skin". There are also patches of purely pink Elabite, however, and one patch of what is either black schorl or a very dark green Elbaite. The pegmatite host in which they are embedded is made up of albite and quartz and contains a very small amount of muscovite.
