This thumbnail specimen consists of a few small Cyanotrichite crusts that rest on what appears to be a brochantite base. The crust is made up of many tiny Cyanotrichite needles, most of which appear to be either crushed or matted down against the base. They do not exceed 0.1" (3 mm) in length, and are at least as thin as a human hair. They are too thin for me to effectively study their form. All have the classic pale blue coloration and pearly luster of their species, and are likely transparent as individuals. The base on which they rest is mostly massive in form, but a few areas contain many thin, green needles.
