This specimen consists of many small, flattened clusters of radiating Aurichalcite needles that rest on a pale-to-dark brown host rock. These needles are generally in good condition, though a few clusters appear to be crushed, and do not exceed 2 or 3 mm in length. They are too fine and intergrown for me to effectively study with a 10-power loupe, but likely have good orthorhombic form. All have a pale blue coloration and a bright pearly luster, and are at least translucent.
