Group of sharp gypsum crystals, transparent, lanceolated, with defined faces and edges. A classic from Spanish mineralogy.

Size: 6.7 x 5.5 x 3.8 cm.
Main crystal: 1.4 cm.
Found in 1988.

Col. Manchion #421, J. Fabre, 1988.
Fluorescent and phosphorescent under long wave UV

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.
Main crystal: 42 x 15 mm.
Found in 1980's.

Fluorescent and phosphorescent under long wave UV

Group of water-clear gypsum crystals, one of them dominant, near to doubly terminated 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 phantom growths in the main crystal and a marked swallowtail twin. Very interesting and representative.

Fluorescent and phosphorescent under long wave UV

In this specimen we can observe different groups of pyromorphite crystals showing hexagonal prisms, some of them truncated by the pinacoid and others more acute. The green tone is presented in some crystals with good transparence and color zoning, while others are almost colorless.
In the town of Munébrega were worked some mines where sulphosalts were exploted. Currently they are collapsed. A specimen from a not common Spanish locality.

Size: 5,8 x 3,0 x 2,8 cm.
Main crystal: 4 x1 mm.
