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.
