The dark gray, banded host rock of this specimen hosts one of the largest clusters of Libethenite crystals that I have seen! Though the cluster is incomplete and has some visible damage, I am pretty sure that most of the damage occurred prior to the mining of the specimen. It has a generally spherical shape and consists of at least 10 small, orthorombic prismatic crystals. These crystals do not exceed 0.1" (0.3 cm) in any dimension, but are pretty large as far as Libethenite crystals go. They appear in the form of four-sided pyramids, many of which are intergrown. Their color is a deep, deep green that appears nearly black, and they have a bright, vitreous luster. Due to the intense depth of color, the crystals are almost completely opaque.
