Heterogenite from La Encontrada Mine, Spain

Heterogenite from La Encontrada Mine, Molvizar, Granada, Andalusia, Spain

Nice little specimen pieces of Heterogenite from La Encontrada Mine, often associated with Malachite or Azurite.

Heterogenite is a cobalt-bearing hydroxide mineral which is often botryoidal - but from this locale, it typically occurs as branching dendrites.

Potentially toxic to handle, as it contains cobalt.
