Azurite Azurite Azurite Azurite Azurite Azurite

Cluster of large, partially etched Azurite crystals from Tsumeb. Fully crystallized all around, even part of the bottom is recrystallized! There is a small indentation showing Malachite on the lower front face (possibly damage, possibly natural), and the lower backside of the back crystal has some indentations/contact from another former Azurite crystal. Otherwise good all around. These good large Tsumeb Azurites are very hard to come by now.

Gemmy, pale yellow Tarnowitzite crystals associated with Malachite. In great condition and colorful. There is a small area on the mid left side where the matrix from the opposite pocket wall contacted. An unusually nice Tarnowitzite that I think is better in person than the photos.
