Several Elbaite crystals rest on the albite base of this specimen. These crystals range in size from a few millimeters along each axis up to 0.8 x 0.6 x 0.5" (2.0 x 1.5 x 1.3 cm). Most of the larger and more exposed crystals have been damaged and broken, whereas the smaller, needle-like crystals that rest between the albite blades are intact. All have good trigonal prismatic form, with rounded triangular cross-sections. Their color is generally a very dark green, but the largest crystal contains the deep red "core" that is indicative of "watermelon tourmaline". The smallest crystals are generally transparent and clear, but the larger crystals are very dark in color and generally contain too many internal fractures to be anything but dimly translucent at best. The albite base is made up of many partly intergrown pseudohexagonal blades, most of which are broken. There are also two small, rounded lepidolite "books" present.
