Where are emeralds found?

The principal Emerald deposits are currently mined in Colombia, Brazil, and Zambia. Emeralds are mined throughout the world (Pakistan, Afghanistan, Russia, Australia, United States) but these are the three major sources.

Where are Emeralds Found?Colombia arguably produces the finest Emeralds. As a general rule, Brazilian Emeralds tend to be darker in tone and more heavily included. The inclusions present in Brazilian Emeralds may be dark inclusions, where the light colored inclusions typically present in Colombian Emeralds (known as jardin) are considered to be less of a factor in adversely impacting the value.

Zambian Emeralds tend to have more of a bluish cast than either Colombian or Brazilian Emeralds, and tend towards a slight grayish cast, which is not present in either Colombian or Brazilian Emeralds. The Zambian and Brazilian Emeralds may also be colored due to the presence of vanadium, whereas Colombian Emeralds usually achieve their coloration from the presence of chromium.

Chivor and Muzo are the two major mining districts in Colombia. Chivor, northeast of Bogota, is in a very rugged terrain with thick forest vegetation. The two major mines of the district are Chivor and Gachala. In this area, the rock is primarily shale and sandstone. Emerald crystals can be found in veins containing pyrite, quartz, and albite.

Muzo is the most famous mining district in Colombia. It is located 60 miles north of Bogota. The climate is hot and humid with relentless rainfall. Muzo, Cosquez, and Pena Blanca are the major mines. Emerald crystals can be found in calcite deposits in shale.

Most of the Emeralds we offer are of Colombian origin, as these tend to have the most widely accepted popularity and represent the best value for our Customers.

Colombian emeralds will typically be the most expensive followed by Brazilian and Zambian stones. The reasoning is related to the color. Colombian emeralds get their color primarily from the trace amounts of the element chromium which is responsible for some of the purest greens in gemstones. Brazilian emeralds get their color primarily from trace amounts of the element vanadium and Zambian emeralds get their color from iron. Brazilian emeralds typically have a slight brown or gray cast and only sometimes match the pure green hue that many Colombian emeralds offer and Zambian emeralds often appear too blue due to their iron content. In reality though, emeralds from all three sources may be colored by more than one element.
