Iridescent maroon fluorite cubes on rhyolite matrix, hematite included and visibly zoned.  The cubic faces show composite growth in the middle of the face, tending to smooth sharp faces at the edges. The fluorite glows blue-purple and the calcite a bright orange under UV. The specimen comes from the Canada Fluorspar Inc. Mine, which was, until recently, mining a fluorite vein in a cluster of fluorite veins that have been mined on and off for decades.  The company identified a significant fluorite bearing structure hosted in the meta-sediments which has been intruded by rhyolite sills and dykes. The Mine is currently closed and it may open again, sometime in the future.
