Emerald is a variety of the mineral beryl, coloured green by trace amounts of chromium and sometimes vanadium. Beryl has a hardness of 7.5–8 on the 10 point Mohs scale of mineral hardness. Most emeralds are highly included, so their toughness (resistance to breakage) is classified as generally poor.

Emeralds, like all coloured gemstones, are graded using four basic parameters – the four Cs of Connoisseurship: Colour, Cut, Clarity and Crystal. A fine emerald must possess not only a pure verdant green hue, but also a high degree of transparency to be considered a top gem.

In the 1960s the American jewelry industry changed the definition of 'emerald' to include the green vanadium-bearing beryl as emerald. As a result, vanadium emeralds purchased as emeralds in the United States are not recognized as such in the UK and Europe. In America, the distinction between traditional emeralds and the new vanadium kind is often reflected in the use of terms such as 'Colombian Emerald'.

Emeralds come from three main emerald mining areas in Colombia: Muzo, Coscuez, and Chivor. They are also found in Afghanistan, Australia, Austria, Brazil, Bulgaria, Cambodia, Canada, China, Egypt, Ethiopia, France, Germany, India, Italy, Kazakhstan, Madagascar, Mozambique, Namibia, Nigeria, Norway, Pakistan, Russia, Somalia, South Africa, Spain, Switzerland, Tanzania, United States, Zambia and Zimbabwe. In the US, emeralds have been found in Connecticut, Montana, Nevada, North and South Carolina. In 1998 emeralds were discovered in the Yukon.

The Emerald stands for love, health and money.
