Layman's explanation:	Emerald is named after the Persian word for green, and is known as the "gem of Spring." The green form of beryl, emerald, is a precious stone that has been valued for a long time. They were previously mined in what was once known as "Upper" Egypt until around 1370. Egypt supplied the trading world, which was India and Europe, with Emeralds. Emeralds are generally dull, opaque stones and are oiled to shine the surface.
