emerald

emerald, the green variety of beryl, of which aquamarine is the blue variety. Chemically, it is a beryllium-aluminum silicate whose color is due to small quantities of chromium compounds. The emerald was highly esteemed in antiquity; the stones were used for ornaments in early Egypt where some of the first emeralds were mined. The finest emeralds are found in South America in Colombia, where they have been mined for over 400 years. The gem was a favorite in pre-Columbian Mexico and Peru, where it was cut in intricate designs. The treasure taken back to Spain by early explorers included emeralds. Good emeralds are the most highly valued of gem stones. Zambia and Brazil are also significant sources of the natural stones. Synthetic emeralds are also manufactured in Germany, France, and the United States. The Oriental emerald, a different gem, is the transparent green variety of corundum.

Emerald

Emerald

One of the most highly esteemed precious stones, known to ancient Egyptians, Hindus, Greeks, and Romans. In India emeralds were used to adorn images in temples, and Moslems used emeralds as amulets, inscribed with verses from the Koran. Emeralds were believed to change color when surrounded by deception and treachery. They were also believed to be preservatives against decay, dysentery, and the bites of venomous creatures and to promote easy childbirth. In ancient Rome the emperor Nero was said to have had an unusually large emerald that he used for viewing gladiatorial contests. Presumably he was shortsighted and used it as a lens.
