Lovely Pyrite Mangano Calcite Couple. Two specimens from the same location were in an old stock box and here they are. One in a triangle crystal shape with mass coating of micro Pyrite on one side. Another light coloured crystals cluster with minor Micro Pyrite. Both of these specimens are fluorescent under the long and short of it. UVC and UVA, just for good measure a few pics showing very brief phosphorescence with a UV laser. Just the kind many crystal lovers choose over more perfect collectible pieces. A super nice piece and something different from the more commonly available.

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.
