Located in the Sierra de Alcarama of La Rioja, Spain, the Ampliacion a Victoria Mine is world-famous for producing exceptionally sharp, geometrically perfect cubic pyrite crystals within Cretaceous marl layers. Formed through hydrothermal metamorphism that mobilized sulfur within the sedimentary rock, the deposit has been actively mined for decades primarily to supply mineral collectors and museums worldwide with stunning, natural metallic specimens.
