The Josefa-Veneros vein is a classic vein of the central Asturian fluorite district and the most famous of those found there. Mineralization is dominated by Fluorite, associated with a hydrothermal system developed along fractures and veins hosted in Paleozoic carbonate and clastic rocks. Low- to medium-temperature fluid circulation led to the formation of fluorites of great quality and mineralogical interest. The discoveries made there between 1970 and 1974, consisting of Fluorite crystals with well-defined crystal developments and often associated with Calcite, so characteristic of the La Collada area, are still one of the world references for collectible Fluorite specimens, both for their crystallographic richness and their beauty.
