This hand specimen consists of a pale brown base rock on which rest several small Aurichalcite clusters. These clusters are generally in very good condition, as one or two show some light or moderate damage. Each cluster is made up of dozens of radiating Aurichalcite needles that do not exceed 0.1" (3 mm) in length. Their orthorhombic, spiky form is reasonably good, though a bit irregular, and all have a pale blue color with a hint of green and a pearly to silky luster. They are translucent, too. The Aurichalcite clusters rest on a druse of tiny calcites that coats a substantial portion of the host rock.
