Description

A single crystal of azurite (58 mm) on a shard of iron-stained country rock. The azurite crystal has localised and concentrically zoned malachite alteration.

The specimen was number 1823 in the collection of Austrian industrialist Hans von Karabacek, part of which was purchased by Harvard University in 1935. This dates the specimen unequivocally to the first oxidation zone.
