This hand specimen consists of a chunk of albite pegmatite in which is embedded several Elbaite crystals. These crystals are generally in fair to good condition, as many are damaged, broken, or incomplete, and the largest one has visible dimensions of 1.1 x 0.4 x 0.4" (2.8 x 1.0 x 1.0 cm). All have excellent trigonal prismatic form, with well-defined edges, clean faces and a rounded triangular cross-section, but very few, if any, possess intact terminations. The smaller crystals are generally a pure pale green in color with a hint of gray or blue, but the larger crystals have a similarly-colored layer that surrounds a "core" of pink Elbaite. All have a slightly dull vitreous luster, and the smaller, green crystals tend to be transparent and very clear, whereas the larger "Watermelon" crystals are only dimly transparent at best due to internal fracturing. The Elbaites are accompanied by a large number of small, intergrown lepidolite "books" and platelets and several broken albite blades.
