JFD23AN6: Although later more sphalerites with Fluorite were found in the La Viesca mine, when the first ones were found they caused much excitement among mineral collectors in Spain due to their novelty. I remember that they were very sought after and that in the end I was able to get one thanks to the deeply missed José Ramón García. Some time later, more pieces of Sphalerite with Fluorite came out, some even with relatively large crystals, although perhaps not as light in color as these first ones.
