As long as pearl jewelry have been known to people, they have been a highly sought commodity for their beauty. It's only in recent times however that the industry has taken the hunt for the perfect pearl to a whole different level. Today, the shiny orbs that we see on in display in jewelry stores have actually almost always been grown in farms. That's a far cry from the dangerous extraction and collection methods used before the invention of modern technology. In the past, not more than 100 years ago, the only way to retrieve pearls was by diving in lakes, floods and the ocean to pick them up, one at the time. The unfortunate divers who'se job it was to do this, were often poor and lured by the relative large sums they could get. The diver would sometimes have to dive as deep as 100 feet on one single breath of air. In order to preserve air and to stay submerged the longest, the divers would hold on to heavy stones on the way down. Naturally, this dangerous activity was reserved for the desperate or the powerless - in many cases slaves or extremely poor peasents. Today, this method is all but obsolete in most places of the world. The cheaper cultured pearls have become popular and are many times the only pearls available to the consumer. There are however still a few isolated areas that practice this old art of pearl diving. Some of the finest natural pearl speciments come from the gulf of Bahrain. Here, divers still risk their health to retrieve what are considered the top of the crop in the world. In fact, Bahrain wants no part of the sale of cultured pearls, banned from trade. Bahrain is one of the few places on earth that does an active job in trying to preserve the natural habitat and waters from pollution. It's an interesting story and one that continues to fascinate buyers around the world. Somehow, the beauty of the pearl grows when it's been retrieved from the depth of the ocean.

Buying pearl jewelry can be fun, exciting and confusing. Whether you're considering a gift of pearl jewelry for someone special or as a treat for yourself, take some time to learn the terms used in the industry. Here's some information to help you get the best quality pearl jewelry for your money, whether you're shopping in a traditional brick and mortar store or online. Pearls Natural or real pearls are made by oysters and other mollusks. Cultured pearls also are grown by mollusks, but with human intervention; that is, an irritant introduced into the shells causes a pearl to grow. Imitation pearls are man-made with glass, plastic, or organic materials. Because natural pearls are very rare, most pearls used in jewelry are either cultured or imitation pearls. Cultured pearls, because they are made by oysters or mollusks, usually are more expensive than imitation pears. A cultured pearl's value is largely based on its size, usually stated in millimeters, and the quality of its nacre coating, which give it luster. Jewelers should tell your if the pearls are cultured or imitation. Some black, bronze, gold, purple, blue and orange pearls, whether natural or cultured, occur that way in nature; some, however, are dyed through various processes. Jewelers should tell you whether the colored pearls are naturally colored, dyed or irradiated. Clams, oysters, mussels and many other mollusks with limy shells are known to produce pearls. But very few kinds yield gem pearls of jeweler's quality. The pearl is an abnormal growth of mother-of-pearl, or nacre, imbedded in the soft bodies of these shellfish. It is built up, layer upon layer, in the same way as nacre is added to the lining of the growing shell and always has the same color and luster. For example, over the country, hundreds of good-sized pearls are found each year in the oysters we eat. Unfortunately these have no commercial value regardless of whether they have been cooked or not because they are dull opaque white or purple like the shell of the parent oyster. In recent times almost all pearls of gem quality come from the oriental pearl oyster which has a bright shimmering translucent nacre. A pearl starts growing when some irritating foreign substance such as a sand grain, bit of mud, parasite or other object becomes lodged in the shell-producing gland called the mantle. Pearls formed in the soft flesh where nacre can be added on all sides are most likely to be spherical and the most highly prized. By far the great majority are flattened or variously distorted and have little value. Size, color, luster and freedom from flaws are other essential qualities. Unlike other gems, such as diamonds, pearls have an average life of only about 50 years. In time the small amount of water in a pearl's make-up is lost and its surface cracks. Because they are mostly lime, necklaces which are worn often are injured by the acid secretions of the human skin.

"(Manouchehr) Mottaki makes these declarations, then he reformulates them," the Frenchman went on. "They rarely provoke enthusiasm, they are rarely very positive.

"We have been waiting for light at the end of the tunnel for almost three years. We will wait until we decide that freshwater pearl jewelry enough is enough a nd that the process is exhausted."

Enrichment of uranium is the most controversial aspect of Tehran's nuclear programme since it can be used both to generate electricity - as Tehran says it is doing - or to make the fissile core of an atom bomb.

Tehran has defied five UN security council resolutions on its controversial nuclear programme, including three with sanctions attached.

"Even if it is clear that talks cannot go on forever, no one wants to give Iran a deadline that is too precise, because otherwise Tehran could just play with it," added another European diplomat.

"I don't want to answer what is going to pearl jewelry wholesalehappen, but I hope they say yes," underlined the EU's foreign policy supremo Javier Solana. "I hope that by the end of the month we'll know something."

Luxembourg - Iran is "wasting time" as the West waits for it to deliver its response on a UN-brokered deal for overseas treatment of low-enriched uranium (LEU), French Foreign Minister Bernard Kouchner said on pearl strandTuesday.

"Iran is wasting time because now is the time for talking," Kouchner said on arrival in Luxembourg for a meeting of European Union foreign ministers. "One day, it will be too late," he added.

"We need answers. We have all shown a great deal of patience."

Foreign Minister Mottaki on Monday said Iran was mulling a United Nations-brokered deal which envisages sending Tehran's low-enriched uranium (LEU) abroad to be converted into nuclear fuel, as a UN team ended its inspection of a newly revealed atomic plant.

Iran's Fars news agency on Tuesday reported that freshwater perl jewelry Tehran will deliver its response within two days.

He said that Russia was concerned by the "lack of transparency" surrounding the Iranian nuclear programme and the sterling silver jewelry possible intensification of the nuclear crisis.

Deputy Foreign Minister Sergei Ryabkov had on Monday said world powers should show maximum patience in the Iranian nuclear crisis and stop accusing the Islamic Republic of time-wasting.

Russian officials have refused to commit publicly to a December deadline laid down by some Western powers for Iran to akoya pearl jewelryease the international concerns over its nuclear drive.

Iran is due to give an answer in the next days to a UN atomic agency-brokered plan for Iranian uranium to be further enriched abroad in states including Russia which is seen as a possible solution to the stand-off.

Western powers suspect Iran could be seeking to develop an atomic bomb under the guise of a civilian nuclear programme, but Tehran strongly denies the allegations that it is seeking a  freshwater pearl strands nuclear weapon.

Moscow - Further UN sanctions on Iran are unlikely in the near future, a top aide to Russian President Dmitry Medvedev said on Wednesday, amid continued Western concern over Tehran's nuclear programme.

"Sanctions on Iran are unlikely in freshwater pearl the near future," Medvedev's top foreign policy advisor Sergei Prikhodko told Russian journalists, according to the Interfax news agency.

The United States has in recent weeks been seeking a concrete commitment from Moscow to freshwater pearl jewelry tough sanctions against Tehran should the current diplomacy aimed at ending the nuclear stand-off fail.

Prikhodko did not give further details on Russia's position, saying he could only repeat a statement made by Medvedev in the United States last month that had initially gladdened Washington.

"Sanctions rarely result in the necessary result but in some cases the use of sanctions is inevitable," Prikhodko said. "This formula remains in freshwater pearl earrings force," he added.

The disclosure of its existence on September 21 triggered widespread outrage in the West, which suspects Iran is enriching uranium with anpearl strand ultimate goal of using it to make atomic weapons.

Tehran strongly denies the charge.

Iran has already been enriching uranium - the most controversial aspect of its nuclear project - for several years at another plant in the central city of Natanz, in defiance of three sets of UN sanctions.

Enriched uranium produces fuel for  cultured pearl jewelry civilian reactors, but in highly extended form can also make the fissile core of an atomic bomb.

The IAEA experts had wanted to compare the information of the plant provided by Iran with what they actually found at the facility.

They also wanted to take environmental samples from around the plant to analyse if any radioactive material has been moved into the facility.

Iranian officials have previously said that no wholesale pearl jewelry radioactive materials have been put inside the plant as it is still under construction.
