Emerald is a gemstone variety of the mineral beryl. Its green colour occurs from trace amounts of chromium & sometimes vanadium. The name Emerald is derived from the Ancient Greek word smaragdos (σμάραγδος) which means green stone. For an Emerald gem to be considered top quality gem material it must possess a pure verdant green hue & a high degree of transparency. Flawless faceted emeralds exceeding 5 carats are very rare. In antiquity Emeralds have been mined in Egypt since 1500 BC. Mining in India & Austria dates to at least the 14th century BC.
Emeralds are formed by hydrothermal processes associated with magma & also through metamorphism. Often found near Quartz & with biotite schists, clay shales, in lime stones & with pegmatites. Emeralds are found all over the world, however modern day mining sees Colombia responsible for 50–95% of world production & by far the world's largest producer of Emeralds. Rare 'trapiche' emeralds are found in Colombia. They are distinguished by a six-pointed radial pattern that consists of ray-like spokes of dark carbon impurities.
The gem industry has created a distinction between Vanadium-bearing Emeralds & Chromium-bearing Emerald. The term Colombian Emerald is attributed to the Vanadium variety. The UK & Europe do not consider Vanadium Emerald / Colombian Emerald to be true Emerald, however the USA does. Many fakes are circulated on the market. Both hydrothermal & flux-growth synthetics have been produced as well as method for producing an emerald overgrowth on colourless beryl.
