A limestone matrix covered on one surface with cobaltian calcite forms the host for several nodules of kolwezite on this specimen. Several of the kolwezite nodules are damaged, exposing a dark greenish-black interior. Were it not for this, they might easily be mistaken for malachite. The back of this specimen has been sawed,revealing small vugs of cobaltian calcite. Nothing can be seen of kolwezite's monoclinic form on this specimen, but this is not really surprising. These rounded nodules are the norm for this species.
