A substantial amount of Annabergite rests on the green- and rust-colored host rock of this specimen. There is very little crystal form visible in it, so it is difficult to ascertain damage, if that concept even applies. There are a few tiny patches of radiating needles that are pressed against the host rock, along with several bits of a thin crust of the pale green material. Where crystal form is visible, there is a pearly luster, but the crusts all have a very dull luster. A substantial portion of the host rock seems to be permeated with veins of these crusts, and the rock in general in that area has a greenish coloration. Other areas of the host rock show a bright, almost rusty coloration that might be due to limonite. It is a rather odd specimen from a locality that I have never heard of before.
