#Emerald is the green gem variety of the minerl beryl, and is mined predominantly in Colombia, Zambia, Brazil, Zimbabwe and Pakistan. In selecting an Emerald, color is the most important factor, and most Emeralds, even of the highest quality, will contain tiny fissures and flaws which do not detract from the value of the stone.
Emerald is the birthstone for May and is rated fair to good for everyday wear. Extremes of temperature and aggressive forms of cleaning may damage the stone.
