This lovely hand specimen is made up almost entirely of intergrown Cylindrite needles. These needles reach nearly 1.5" (3.8 cm) in length and are generally in good condition - though many are noticeably damaged, several have complete terminations, including one particularly exposed crystal. All have a thin, cylindrical habit and are considered trigonal in form. Their gray color and dull metallic luster are standard for the specie, and all are, of course, opaque.
