Fine aquamarine crystals have been found at the Fernandes Quarry, Mimoso do Sul, Virgem da Lapa mine, and Linopolis area of Minas Gerais, Brazil; Jos mine, Nigeria; Mt. Antero, Chaffee County, Colorado; Alabashka, Ural Mts., Russia; and at Dusso, Gilget division, Pakistan. Dusso is extremely remote and very high at about 4,270 meters. Numerous pegmatites have produced many wonderful pale blue aquamarine crystals in euhedral form. Doubly-terminated crystals are quite common. Many aquamarines are jacketed at the center with white albite leaving the terminations exposed. Some deposits are still being worked. Aquamarine, which has been found in Egyptian, Greek and Roman Tombs, was highly prized by the ancients and was called the 'sweet tempered' stone. It was thought to cure numerous ailments and to guide the wearer through all manners of difficulties.
