It is a precious gemstone and a variety of the mineral beryl. Colored green by trace amounts of chromium and sometimes vanadium. Most emeralds are highly included and are a relatively strong gemstones, registering 7.5 - 8 on the Mohs scale. While they are fairly resilient to knocks, they can be chipped or scratched. Emeralds usually have numerous inclusions and surface breaking fissures. Due to the inclusions within an emerald, it is not wise to clean these gems in an ultrasonic cleaner. Instead, clean gently by hand using warm water. If an emerald has no visible inclusions to the eye it is considered flawless. Stones that lack surface breaking fissures are extremely rare.
The first known emeralds were mined in Egypt around 1500 BC. It was the favorite gem of Cleopatra, the Queen of Egypt. The Emerald mine in Upper Egypt, rediscovered a hundred years ago near the Red Sea, was one of the earliest Emerald occurrences in human history. Colombia is the world's largest producer of emeralds, constituting 50–95% of the world production. In the US, emeralds have been found in Connecticut, Montana, Nevada, North Carolina, and South Carolina.
