20073 Azurite, Malachite, Calcite, Triako open cut, Mineral Hill, Condobolin district, New South Wales

Not all mineral specimens are perfect. This one has suffered a little, perhaps when mined or perhaps when collected. One of the azurite crystals (the one on the right) has a couple of breaks. One of these shows the perfect cleavage property of azurite (in one direction anyway). The second is a ragged crack that runs through both the quartz matrix and the azurite crystal. This is certainly not a cleavage plane! Ex Margaret Brown Collection. Width of view 3.5mm. Stack of 60 images.
