| What
diferences are between Natural, Cultured pearls and imitations
? |
 |
|
All Natural Pearl is produced by pearls Oyster, alive beings. Each pearl
is a true
gift of the Nature. Within pearl is distinguished between Cultured pearl,
Natural pearls. The only difference among them is that Natural pearls
begin to take
place by a natural accident whereas the Cultured pearls are initiated
by
the action of the man. In addition to the boot of the generation of pearl,
the man also takes part in the development of the same one,
preparing to the Oyster in farms adapted in temperature, currents and
hygiene,
to favor the pearl development . Cultured pearls approximately represent
a 95%
of the commercialized amount. A generally experienced jeweler can observe
by the hole that crosses to per it and to determine its origin. Nevertheless,
the only
safe way to differentiate between a Cultured or Natural pearl is through
x-rayses.
On the other hand, imitation pearls are done by the man through industrial
and mechanical processes. One is repetitive and identical pieces that
lack the value
of a true jewel. The best ones imitation pearls are done of accounts of
glass, covered
ceramics, shell or plastic with a varnish generally made of lacquer and
grudges of fish
crushed to simulate the shine and the color of pearl. Imitation pearls
are known by
many names. Some of these names, unfortunately, are used to deceive the
consumer.
Simulated ", "organic" the words "fashionable",
"of style", "false" (faux), ",
"done by the regional man", "Majorca", or other names,
are all terms that are
applied when made of imitation pearl. Most of the experts in pearls can
appreciate
the difference between imitation pearl and an authentic one with seeing
it.
Nevertheless, thanks to sophisticated manufacturing techniques and completion,
the consuming means can be difficult to at first distinguish between an
authentic pearl
and a good imitation. A way easy to find out is making it the "TEST
Of the TOOTH":
• If a string of imitation pearl with the teeth is close slowly,
the tact will be smooth.
• a string of Per them Authentic will feel a little sandy. This
"sandy" sensation
comes from the crystalline structure of the nacre that forms the authentic
pearl.

| What
diferences are between Fresh
and Salt water
pearls ? |
|
The biological process that are developed for the generation of a pearls
in an Oyster,
as well as the techniques of cultive, are exactly equal, independently
in question of cultuive in salt water or fresh water. The differences
between pearl of
salt water and fresh water are not in generated pearl, therefore, it is
necessary
to look for them in the conditions of surroundings:
The seas of the Australian Continent, where sister generated the Australians
pearls
and Tahitians, characterize themselves by their tempered and calmed waters
that is suitable for the development and express growth of pearl.
The rivers of the southwest of Asia, from where they come the great majority
of Freshwater pearls, they reunite suitable characteristics for the cultive
of pearls,
characterizing itself by the barren water detents which the rivers are
constructed together. The Japanese rivers and lakes nested the cultive
of
the pearl of Biwa. They were produced fresh water pearls of the high quality
in the
Biwa lake in Japan. The production has stopped, basically due to the contamination.
The seas of Japan, are the source of the Akoya Pearl. At the present time
the frequency of the red tides and other plagues, together with the problems
of the
contamination that are generated in Japan, have taken to a decrease in
the production
of the farms, going off the prices of this type of per them, without quality
improvement.
Some rivers of the South center of North America and the oceanic coast
of the
northwest of Mexico and California, are scenes where it is successfully
beginning
activities of culture of different Oyster.
Cultured pearls of fresh water they suffer of stereotypes. Most of people,
when
it hears speak of " fresh water pearls" thinks about which commercially
"rice grain"
is called . These cheap pearls were produced massively in fresh water
in the Eighties.
The fashion of this type of pearl happened, and the fresh water farmers
were
themselves led in a deep crisis that motivated to them to improve their
techniques,
obtaining a progressive and drastic increase of quality, that at the moment
equals
and surpasses to some types of cultive in salt water.

| How a pearls borns? |
|
The birth of a pearl is a wonderful event. Unlike precious stones or
metals that must
be extracted of the Earth, per they are created them by ostras alive in
the depths of the sea. The precious stones must polish before they show
his beauty; pearls do not need
them such treatments to reveal his enchantment. Mothers with luste
are born of oyster and smooth internal brightness that is not equaled
to any other
gem in the world. Natural pearl life begins when a strange object, like
a parasite
or a particle of sand, lodges by accident in the smooth body of oyster
from which
it cannot be expelled. In a effort to alleviate this annoyance, the body
of oyster
initiates a defensive action. Oyster begins to secrete a smooth and simultaneously
hard crystalline substance around the irritating object, with the purpose
of protecting
itself. This substance is called nacre. While the strange body remains
within the body of
oyster, this one will continue secreting nacre around the object, castrates
after layer.
After several years, the irritating object will be locked up totally within
this silky
crystalline layer. The result: appraised and the shining called gem pearl.
But, how the precious pearls form of which one oyster considers simple
protection
against the irritation, he is one of the appraised secrets more of the
nature.
Since nacre is not only one tranquilizing substance. He is compound of
microscopic
crystals, each one aligned perfectly with the other so that the light
that happens
through the axis of one is reflected and refracted by other to produce
a rainbow
of light and color. Cultured pearls form by oyster of almost identical
way.
The only difference is that the hand of the man surgically implants the
irritating
object - a small piece of polished shell - in oyster, instead of leaving
it at random to it,
and soon it is made to a side to leave nature it and oyster builds the
miracle.

| How old are pearls in
jewelry ? |
 |
Many thousands of years ago, long before written history, human beings
probably
discovered the first pearl while searching the seashore for food.
Countless references to the pearl can be found in the religions and mythology
of cultures from the earliest times.
The ANCIENT EGYPTIANS prized pearls so much they were buried with them.
Cleopatra reportedly dissolved a single pearl in a glass of wine and drank
it, simply
to win a wager with Mark Antony that she could consume the wealth
of an entire nation in just one meal.
In ANCIENT ROME, pearls were considered the ultimate symbol of wealth
and social standing.
The GREEKS held the pearl in high esteem for both its unrivaled beauty
and
its association with love and marriage.
During the DARK AGES, while fair maidens of nobility cherished delicate
pearl necklaces,
gallant knights often wore pearls into battle. They believed the magic
of these
lustrous gems would protect them from harm.
Throughout history, pearl has been one of appraised and coveted gems more.
The Renaissance saw the royal courts of Europe awash in pearls. Because
pearls were
so highly regarded, a number of European countries actually passed laws
forbidding anyone but the nobility to wear them.
During the European expansion into the New World, the discovery of pearls
in Central American waters added to the wealth of Europe. Unfortunately,
greed and
lust for the sea-grown gems resulted in the depletion of virtually all
the American pearl oyster populations by the 17th century.
Until the early 1900's, natural pearls were accessible only to the rich
and famous.
In 1916, famed French jeweler Jacques Cartier bought his landmark storeon
New York's
famous Fifth Avenue -- by trading two pearl necklaces for the valuable
property.
But today, with the advent of pearl cultivation, pearls are available
and affordable to all.
Cultured pearls have the same properties that natural pearl
and are cultured in oyster alive. The only difference is just a little
bit of
breath that puts the human being.
