Important Emerald Mines In The World @ Jewel Info 4 U
SUMMARY: Emerald deposits
are found all over the world, the
primary mines being in parts of USA,
Brazil, Madagascar, Africa, India
and Australia.
Emeralds - Their use and their
origins have been traced back to
India and Egypt, to about 5000 years
ago with the name being derived from
the Greek word 'smaragdos' meaning
the 'green stone'. The 2205 carat
"jug", cut from a single crystal in
the Viennese treasury is one of the
famous crystals. The May
birthstone
and the stone for
20th and 35th
anniversaries is the Emerald.
 Courtesy: Orbital Joe Emerald is a 'cyclosilicate' and it
is mostly found in a crystal form
and it is a hexagonal prismatic. An
emerald is a deep green beryl with a
vitreous luster that comes in a
hardness scale of 7.5-8. The
emeralds chemical composition is
aluminum beryllium silicate Al2Be3
(Si6O18). It is sensitive to heat
and pressure due to which it has a
brittle tenacity and conchoidal
fracture. Beryl has a specific
gravity of average to medium high
2.66 - 2.87 with a refractive index
of 1.562 - 1.602 and may have an
uneven distribution of color, though
its color is stable in heat and
light. It is also possible to have
cat's eye and asterism stones also.
The chromium, also called the
impurity element and possibly some
vanadium give
emeralds their green color. The
general belief is that chromium is
what defines the emerald whereas
vanadium is just green beryl.
Emerald, with a dispersion of 0.014,
is transparent but generally clouded
with inclusions with a blue green
and a yellow green color due to the
presence of
Pleochroism. It is advisable
never to clean emerald in steam
cleaner or an ultrasonic bath due to
its tendency of being brittle.
Cutting of emeralds is an art in
itself. It can be either step cut,
faceted or fashioned "en cabochon".
The emerald cut is a step cut that
was developed in the 17th century.
Private Emerald Mine Russia
The Urals Mining Co. was founded in
2005 and now they hold the rights
for the development of the
Sverdlovsk emerald deposit, located
near the village of Malyshevo. It
has been found that this deposit has
reserves to the tune of over 600 kgs
of emeralds in the C1 and the C2
types. This private company is the
first to be seen in the Russian
market for emeralds. No other mine
is operating in Russia as of now.
North Carolina
In the United States, the Emerald
Hollow Mine is open for prospecting
and it is the only mine to do so.
This mine sits snug at the foothills
of the Brushy Mountains in North
Carolina in the small town of
Hiddenite. On the North American
continent this place holds the first
place as one of the most unique and
fascinating geological location.
There are over 60 types of minerals
and gems that occur naturally and
you will find some rare gems like
the garnet, topaz, aquamarine,
citrine, amethyst, sapphire, quartz
crystals to name a few. Hiddenite is
a very rare gemstone and it can be
found only in Hiddenite the village.
Columbia
There are the various geological
conditions in which beryl is found
and this includes conditions like
metamorphic schist, greisens and
volcanic rhyolites which are hydro
thermally formed. The Columbian
deposits are hydrothermal in origin
and the hot water passes through the
calcite rich rocks. The Columbian
mines have deposits of emeralds that
can be distinguished by their matrix
rock. The deposits are hand worked
and the gems are unearthed from the
white and gray calcite of the
pegmatic veins and from carbonaceous
shale. Unfortunately about 70% of
these are lost in the process of
faceting.
Minas Gerais Mining Locations
Brazil
Minas Gerais means "general Mines"
and the state of Minas Gerais was
created by the Portuguese colonists
in the year 1720 while on a quest
for gold, gems and other treasures.
To the north East lie the cities of
Teófilo Otoni and Governador
Valadares and these hold the
reputation of being among the major
industries of gemstone, as they are
located very close to some of the
richest gem mines of Brazil. There
are large amounts of gems like
diamonds, kunzite,
aquamarine and emeralds,
Chrysoberyl and tourmaline and
also morganite.
Emeralds from Madagascarrr
The emerald mines of Kianjavato are
situated in eastern Madagascar in
the rain-forest about 60 km west of
the coastal city of Mananjary. This
mine sits a little north of a town
called Irondro in the region of
Vatovavy in the province of
Fianaranatsoa. These Emerald
deposits found at Kianjavato are
about 3 billion years old and they
are pegmatite rocks. The emeralds of
Madagascar Emeralds are mined 350 km
east of Toliara town at the Ianapera
deposits in the Tuléar Province.
There are a lot of other emerald
deposits in the world and they are
found in the African nations of
South Africa, Ghana and Zimbabwe.
There are others in Mozambique,
Namibia, Nigeria and Malawi. Also
India, Australia and Pakistan too
boast good
emerald deposits.
