Cerro Patillas, Fuentes de Ebro, Zaragoza, Aragón, Spain

Group of water-clear gypsum crystals, one of them dominant and with a good size. They show a magnificent luster and transparency and very well defined edges and faces. Disposed very aerial on a white alabaster matrix covered by small gypsum crystals. In this specimen we can observe a marked swallowtail twin in one of the crystals and defined terminal faces in others. Very interesting and representative for the best display.
Under short and long wave ultraviolet light sources these specimens show intense fluorescence and long live phosphorescence. Selenite specimens from Fuentes de Ebro quarries have been considered the best ones worldwide.

Size: 7,0 x 6,8 x 5,5 cm.
