A moderate dusting of tiny Libethenite crystals rests on the host rock of this specimen. Under 10-power magnification, one can see that the crystals have a definite form, but their intergrowth and small size make it difficult to define their shapes. According to my best estimations, though, they appear to have the standard orthorombic prismatic form with a diamond-shaped cross-section and a shallow, 4-faced dome. Their color is the dark forest-green that is common for Libethenite, and they appear to have a pearly to vitreous luster and are at least translucent. While examining the crystals under magnification, I also saw several small, rounded orbs of material among the Libethenites that have a much bluer, almost emerald-green coloration and are likewise translucent. I do not know what they are made of. There are a few substantial spots of damage on the cluster due to impact, but most of the crystals are in excellent condition. They rest on an almost granitic mixture of feldspar and quartz.
