Several Elbaite crystals are embedded in the pegmatite matrix of this hand specimen. All of these crystals are damaged and incomplete, and the largest, having visible dimensions of 1.4 x 1.0 x 0.4" (3.6 x 2.5 x 1.0 cm) is the least complete. Only a few small crystals show any trigonal prismatic form, as damage is too severe in most. The largest crystals possess a dark green skin that surrounds a pink core, denoting watermelon tourmaline, and are translucent at best and intensely internally-fractured. The smaller crystals are generally a dark, slightly olive-green color and likely dimly transparent. A small amount of mica is also embedded in the pegmatite matrix.
