Introduction and History
Emerald is derived from a Persian word meaning "green gem". It changed from Greek to Latin as smaragdus, then to esmaurde, esmralde, and in the 16th century to esmeralde.
Emeralds are ancient gemstones. According to the oldest book in the world, the Papyrus Prisse, "But good words are more difficult to find than the emerald, for it is by slaves that it is discovered among the rocks."
