The Beryl group of minerals is a powerful stone group with
differing properties for each gem of the species.

Beryl crystals have been known to grow to 18 metres in length.

Emerald is a gemstone and a variety of the mineral beryl coloured green by trace amounts of chromium and sometimes vanadium. Emeralds, like all coloured gemstones, are graded using four basic parameters – the four C‘s of connoisseurship:
color, clarity, cut and carat weight.
Normally, in the grading of coloured gemstones, color is by far the most important criterion. However, in the grading of emeralds, clarity is considered a close second.

A fine emerald must possess not only a pure verdant green hue as described below, but also a high degree of transparency
to be considered a top gem.

In the 1960s, the American jewellery industry changed the definition of emerald to include the green vanadium-bearing beryl. As a result, vanadium emeralds purchased as emeralds in the United States are not recognised 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 in antiquity were mined in Egypt at locations on Mount Smaragdus since 1500 BCE, and India, and Austria since at least the 14th century CE. The Egyptian mines were exploited on an industrial scale by the Roman and Byzantine Empires, and later by Islamic conquerors. Mining ceased with the discovery of the
Colombian deposits; only ruins remain.

Colombia is by far the world's largest producer of emeralds, constituting 50–95% of the world production, with the number depending on the year, source and grade. Emerald production in Colombia has increased drastically in the last decade, increasing by 78% from 2000 to 2010. The three main emerald mining areas in Colombia are Muzo, Coscuez, and Chivor.
Rare "trapiche" emeralds are found in Colombia, distinguished by ray-like spokes of dark impurities.

Zambia is the world's second biggest producer, with its Kafubu River area deposits (Kagem Mines) about 45 km (28 mi) southwest of Kitwe responsible for 20% of the world's production of gem-quality stones in 2004. In the first half of 2011, the Kagem Mines
produced 3.74 tons of emeralds.

Emeralds are found all over the world in countries such as 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, the United States, Zambia, and Zimbabwe. In the US, emeralds have been found in Connecticut, Montana, Nevada, North Carolina, and South Carolina. In Canada, in 1997 emeralds were discovered in the Yukon. Emerald occurs mostly in mica schists and silica rich granites associated with feldspar, mica and quartz.
