Lenticular Azurite crystals forming an interlaced cluster of crystals, on matrix, of a very uniform and intense electric blue color, bright, and accompanied by green Malachite crystals that provide a beautiful color contrast.
The specimen, of high quality for the locality, comes from the collection of Fermín Clemente.
Santa Flora Mine belongs to the Sierra Norte mining district of Seville, within the Ossa-Morena Zone, a Paleozoic geological domain affected by the Variscan orogeny. Mineralization is mainly hydrothermal vein-type, hosted in fractures and shear zones developed in Hercynian metamorphic and igneous rocks.
The veins are dominated by metallic sulfides, mainly of lead, zinc, and copper, with gangue minerals such as Quartz, Calcite, and Baryte. This mineralization style is typical of Variscan hydrothermal systems in the area, historically worked through small to medium-scale mining operations controlled by regional structures.
