Description
A radiating spray of sharp, composite, prismatic azurite crystals (to 140 mm), completely replaced by malachite. A little indeterminate (carbonate) matrix adheres at either end of the specimen.
Neither the provenance of this specimen nor its location in the mine are recorded. However, the size and habit of the crystals and the apparently complete replacement are typical of the first oxidation zone although this cannot be confirmed.
