Washington DC - Natural History Museum - Indian Emerald Necklace

Emeralds are generally classified by the place they come from, so we would discuss about the types and mines of Emerald together.

  • Zambian Emerald – although discovered in the late 40’s was not commercially mined until the 1950’s. Zambia, today is one of the worlds’s leading producers of fine Emerald. Its known for its intense color, remarkable clarity and retains its magnificent hue even in small stones of less than 0.5 ct. This makes it most highly prized variety of Emerald.
  • Columbian Emerald – Columbia is the biggest producer of emeralds these days, both in terms of quantity and quality. These are mainly sought after for the large crystals and therefore bigger stones.
  • Sandwana Emerald – Coming from Zimbabwe, they have stunning color and are known for the inclusions inside. They look very similar to Zambian Emerald.
  • Brazilian Emerald – Brazil has been supplying emerald to the world market since the 1980s. Brazilian emeralds are generally lighter and yellowish in shade.

Emeralds are found in many other countries too – including Afghanistan, Australia, Austria, Brazil, Bulgaria, Canada, China, Egypt, Ethiopia, France, Germany, India, Italy, Kazakhstan, Madagascar, Mozambique, Namibia, Nigeria, Norway, Pakistan, Russia, Somalia, South Africa, Spain, Switzerland, Tanzania and United States.

Syenthetic Emerald – The first commercially successful emerald synthesis process was that of Carroll Chatham. However the process did not run out to be commercially much viable. Another process known as hydrothermal flux process by Pierre Gilson Sr., began to be used in the production of synthetic emerald since 1964.

So this was all we had for mines and types of Emerald, we will be back with more info on Emeralds sooner. If you want to share anything, do email us.
