JFD06AN5: One of the best pockets at La Viesca, of the many found at the beginning of this century, was the one called 'Coquera de la Calcita' which produced large Fluorite crystals with a lot of color zoning and a lot of transparency. There was a lot of calcite in that vug so this piece (the one I kept from that vug) shows small white coatings of that mineral. A quite spectacular piece that has made me very happy all these years.
