The name "emerald" originates from the Greek word "smaragdos" which
just meant "green gemstone". The English word comes from the French
Emerald belongs to the multi-colored beryl family, and is a
beryllium-aluminium-silicate with the Mohs hardness of 7.5 - 8. Its
green color comes from traces of chrome, vanadium or iron within
the usually colorless beryl mineral. Emeralds grew during
complicated tectonic processes whose traces are still visible
within the crystals: foreign, tiny crystals, fissures, fluids,
bubbles etc. These inclusions are called "jardin" (French word for
"garden"). A decent "jardin" doesn't reduce the value of an emerald
as long as it is not spoiling the color or transparency.
Egyptian pharaohs ran emerald mines (the "Zubara Mines") since the
13. century B.C. in the Assuan Valley in Egypt (south of Kosseir:
Jebel Sikait and Jebel Sabara). From there emeralds were sent
(probably until the 17. century) even to Europe, Iran, Turkey, and
Since hundreds of years emeralds were mined in Peru by the Incas.
They regarded emeralds as holy stones. In 1532 Francisco Pizarro
(1476-1541) and his Spanish conquistadors conquered the Inca
imperium in the Peru mountains. Because the Spaniards were
unsuccessful in finding naturally occurring emeralds, their
soldiers confiscated all available emeralds, sometimes as large as
pigeon eggs. To test their genuineness, they pounded the stones
with hammers because they believed that genuine emeralds could not
be broken. Sooner or later they learned that this "green glass" was
more valuable... Finally Spanish galleons carried enormeous
quantities of all available emeralds to Spain. Many ships sank, and
therefore a lot of finest and most valuable emeralds are still
"sleeping" at the bottom of the Carribean Sea.
Formation and Resources
Emerald crystals can grow in hydrothermal veins if all necessary
conditions and elements are present. When hydrothermal fluids
escape from the magma, and cool in deposit veins with fractures in
them, crystals appear. Colombian emeralds were formed in this
manner. They are associated with calcite deposits.
Other emeralds grew in pegmatite deposits similar to the
hydrothermal process. But here the hot water was replaced by magma
or molten rock. When the magma began to cool, the necessary
elements were left in solution and could also create emeralds.
Emeralds are found worldwide. The most sought-after gems come from
the "Emerald belt" in the Cordillera Oriental, a part of the
Colombian Andes, with its famous mining areas Muzo, Chivor, Cosquez
and La Pita. The Muzo area is located near the town Muzo, about 100
km northwest of Bogota. Muzo and Coscuez (about 12 km north of
Muzo) are the major mine areas in the Muzo area. The Chivor mining
area is located about 90 km east-northeast of Bogota. The two major
mines are Chivor and Gachala near the town Somondoco. Chivor is a
very old mine which was already ran by the Chibcha Indians in
pre-Spanish times. The mine was re-discovered in 1896.
Until today many illegal miners ("Guaqueros") are busy in the
Colombian emerald mining areas.
The second important locality of emerald deposits is the Takovaya
River in the Ural Mountains (discovered in 1830). Some Ural
emeralds are quite equal to Colombian stones regarding transparency
and color. Since 1883 the Marinky Mine was established (near the
village of Malischewo), the most important deposit of Russian
emeralds. Today Siberian emeralds play only a minor role in the
Valuable emeralds come also from Africa and Brazil. Some of them
even look like Colombian ones, and in general they are cleaner than
them. Today Zambia and Zimbabwe are important sources for good
stones. In the northern part of Zambia mines were established near
Kagem, Kitwe, Miku und Mufulira.
Since 1984 light green to yellowish-green emeralds were found near
Dayakou / Wenshan Mountains / Yunnan / China. They occur in up to
1.5 m thick pegmatite veins, accompanied by feldspar, mica, quartz,
scheelite, and tourmaline.
