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.
