EMERALDS
BY: JADE C.
The princicpal Emerald deposits are currently mined in Colombia,
Brazil, and Zambia. Emeralds are mined throughout the world (Pakistan, Afganistan,
Russia, Australia, United States) but these are three major sources.Colombia
arguably produces the finest Emeralds. As a general rule, Brazilian
Emeralds tend to be darker in tone and more heavily included.
The inclusions presents in Brazilian Emeralds may be dark inclusions, where
the light colored inclusions typically presents in Colobian Emeralds (Known
as jardin) are considered to be less of a factor in adversly impacting the
value.

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.
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.
