Several tiny sprays of radiating Annabergite crystals rest in a hollow in the host rock of this specimen. The crystals are very small, as they do not exceed 0.1" (3 mm) in length, and are generally in good condition, though a few of the most exposed clusters are crushed and incomplete. Under a 10-power loupe, the crystals appear to have a good monoclinic, rhombus-shaped tabular form. They also appear to be transparent and moderately clear, though without magnification these traits cannot be determined. All have a bright green coloration and show glimpses of a pearly luster. The hollow in which they rest is lined with tabular calcite crystals that are stained a pale brown, and the host rock appears to be made of both calcite and possibly limonite.
