NXP16CD6: Very aerial floater Fluorite specimen made up of cubic crystals with well defined faces and edges and polycrystalline growths of a bluish color typical of La Viesca, forming staggered growths on which Quartz crystals have grown in a very aerial way, probably by epitaxial growth on an ancient Calcite crystal already completely dissolved when the Quartz was precipitated.
A very characteristic and notable example of what the La Viesca Mine, which closed in 2021, used to offer.
