Three fascinating pale sea-green Fluorite crystals sit on a milky Quartz matrix sprinkled with 1 to 3 mm Galena and Chalcopyrite crystals. From the Naica mine at Mun. de Saucillo in Chihuahua, now famous for its discovery of gigantic gypsum crystals in the ‘Cave of Swords’. The Fluorite crystals show octahedral growth but are overgrown with epitaxially aligned cubic crystals forming neatly stacked pyramids. A great specimen and a good and rare example of epitaxial crystal growth.
