The word emerald comes from the Latin smaragdus which means green.
Emeralds come in various shades of green, from deep darkish green to pale green. The most valuable emeralds are a pure, vivid green with a concentrated, pure hue which does not include traces of other shades such as brown or yellow. Emeralds are relatively strong gemstones but can be chipped or scratched.
Emerald is the birthstone for May. It is also a traditional gift for those celebrating 20th or 35th anniversaries.
Emeralds are thought to be the preservers of love and symbols of hope. The color of nature, they are said to relax a troubled mind.
