MALACHITE PSEUDOMORPH AZURITE
A rare mineral specimen of Malachite Pseudomorph after Azurite. You can see that the Malachite is not in one of its natural forms, but instead is more like Azurite. A pseudomorph is when one mineral is chemically replaced by another mineral without changing the external form of the original mineral. In this case the Malachite has replaced the original Azurite mineral. Bright flashes of green from chatoyancy striations of the Malachite. Azurite shows good forms of chisel top tabular prismatic crystals jutting out from the matrix. Very collectible piece, both for it is a pseudomorph and a rare mineral from a great location. An excellent gift or treat for the mineral collector and a must for the Collection. For enhanced display is mounted on perspex pad, ready to go straight into your cabinet.
