Floater rhombohedral Siderite crystal with apparent foliations that really are recrystallizations. Its honey color and the transparency are not usual for Siderite from this mine, generally it is more opaque. There is an associated growth of uncommon doubly terminated Fluorapatite crystals, between translucent and transparent, bright and white in color. These unexpected Fluorapatite crystals have been analyzed and we will send a copy of the analysis to the buyer.
