De Beers diamond traders give up de facto monopoly

2011-11-23T02:10:00.001-08:00

Mine company purchased precious stones for price support

The South African diamond company De Beers is on its role as guardian
of the most sought-after gemstones in the world. 66 years controlled
the company through its monopoly sales organization, with the Central
Selling Organization (CSO) in London, nearly 65 percent of world trade
rough diamonds.

Now the company will function as the "buyer of last resort" to give
up. This, the Group announced in London. "Our strategic realignment is
one of the most important steps of development of the diamond industry
since the 30s," said Nicky Oppenheimer, chairman of De Beers.

Especially in the U.S. the group has repeatedly accused the monopoly
of the CSO. In future De Beers as a "supplier of choice" (supplier of
choice) act. This means that De Beers stopped buying up the excess
supply of rough diamonds on the market and hoarding in order to
stabilize the diamond price.

Now the mining company is trying to increase the demand for diamonds
by a massive marketing campaign through its subsidiary Diamond Trading
Company (DTC). The group plans to focus on the mining activities and
try to reduce its stock of rough diamonds. Late last year, after all,
this amounted to 3.9 billion dollars (8.2 billion DM / Euro 4.2
billion).

"We must act in a customer-oriented," Oppenheimer founded the step.
The new concept will De Beers for the challenges of the 21st Century
make.

Gary Ralfe, managing director of De Beers, pointed to the "enormous
untapped potential" back. The luxury goods market is growing annually
by ten percent. The participants in this sector usually give from six
to ten percent of their revenues on marketing. In contrast, the
diamond industry investing has been little more than one percent in
marketing.

At the same time, De Beers aims to introduce ethical standards. De
Beers' future demands of its 125 large customers, a written
certification that they comply with "best practice principles". This
means that the customers may not trade in diamonds that originate from
these war zones.

Star turns into a diamond planet

Astronomers have discovered a planet in our galaxy of diamond. The small satellite has a higher density than any previously known planet.

Astronomers have discovered a star that was umwgewandelt and compacted to a planet - probably in large part from diamond. The unusual Trabant had a far greater density than any other planet tracked says an international team of researchers at Bonn participation in the U.S. journal "Science."

Once again, super-diamond discovered in South Africa - diamond sales to buyers result.

The precious planet orbiting a star is also unusual, called a pulsar. Pulsars are burnt out suns, which are collapsed into itself. You send a focused beam of radio waves into space that sweeps regularly with the rotation of the stellar corpse on the ground.

The pulsar-planet pair is located about 4,000 light years away in the constellation of the Serpent (Serpens). A light year is the distance that light travels in one year, and corresponds to almost ten trillion kilometers. The planet was found with the 64-meter Parkes radio telescope in Australia.
What you should know about the cosmos

Is the universe infinite?

The cosmologists can not say for sure. Maybe so, according to new measurements, it has a diameter of at least 155 billion light years (in kilometers: 155 followed by 22 zeros). In any case, it is unlimited as a ball: you can move on her endlessly, without encountering a border. The shape of the universe, is unclear, a case for some form of a bean.

How far "out there" were we?

Equipped with visual and digital information about the earth and the human spacecraft "Voyager1" is located about 15 billion kilometers, thus leaving just up our solar system. It is located just where the solar wind, the deadly cosmic radiation slows down and distracted.

Are we alone in the cosmos?

So far been no evidence of life beyond Earth. There are two theories. One says: intelligent life is extremely unlikely, because to many conditions must be met. Moreover, the universe is billions of years old civilizations, however, perhaps only several thousand years old before they go under. Collect their signals is due to the narrow time window, extremely unlikely. Other researchers say: There are billions of planets, somewhere there should be too complex life.

How dangerous are asteroids?

Especially in the early days of the solar system many large asteroids are stamped on the earth. Since then the incidence has declined steadily. More trade was wiped out by asteroids, most of the animal and plant species. Currently, the researchers expect all 50 to 1000 years inflicts a strike, the local destruction. Every 100,000 years it is expected an impact, the civilization "zurückbombt in the Stone Age." Asteroid theory, could be a probe that bears a nuclear bomb to distract from the Earth's orbit.

What is the end of the earth?

The sun is always shining stronger and expands it. In about two billion years, therefore, the surface temperature of Earth will be at 100 degrees. Finally they swallow Mercury and Venus and the Earth's surface transformed into an ocean of lava.

Why the stars are round?

All the stars, in particular, our Sun and all planets and moons are clustered together under the influence of the attraction of its own mass into a ball. That is the lowest energy and most stable form. However, this is only approximate. Because rotating planet like Earth, are flattened by the centrifugal forces in logistics at the equator something. The diameter of the Earth is between the poles less than 40 kilometers at the equator.

Black holes are dangerous?

Theoretically yes, practically no. Our solar system rotates initially at a safe distance around a black hole that sits in the center of our galaxy, the Milky Way. But this black hole sucks but gradually the surrounding matter to himself - billions of years in our solar system. But then life on Earth will be long gone.

What is dark energy?

An exact explanation for this has been a scientist at hand, yet it is certain that there is the so-called dark energy. She is responsible for ensuring that the stars in the universe fly apart faster and faster. Actually, it was assumed that the expansion of the universe after the Big Bang slowed by the gravitational attraction. Measurements showed, however: they accelerated. For the quasi-anti-gravity of dark energy is responsible.

Life came from outer space?

Researchers have actually discovered biomolecules in space - including amino acids. Therefore, there is the theory that molecules from space that came to Earth with asteroids, the origin of life have influenced. But this is not proven.

In the signal of the recently discovered pulsar PSR J1719-1438, astronomers discovered the characteristic fluctuations, indicating a massive companion. From careful analysis of these periodic fluctuations, the researchers conclude that this satellite is about half as big as the planet Jupiter in our solar system orbiting the pulsar and very quickly: One orbit lasts only two hours and ten minutes. Thus, the Planet of the pulsar are so close that its gravity would tear him actually.

Obviously it is a very compact, supermassive object. "The density of the planet is at least as high as that of platinum," said the head of the research team, Professor Matthew Bailes of Swinburne University of Technology (Australia) in a statement.

The research team believes that the planet is the tiny core of a once massive star that is only narrowly escaped complete destruction. It could only be regarded as a so-called white dwarf, which has lost 99.9 percent of its mass to the pulsar.

The remaining core probably consists mainly of carbon and oxygen in crystalline form. Diamonds are special, highly dense carbon crystals. A large part of the planet is therefore likely to be built like a diamond conclude the researchers.

Campbell's rough diamonds to the police

13 years kept under wraps

The story of "blood diamonds" that the British top model Naomi Campbell may have received from ex-Liberian dictator Charles Taylor goes into a new round. A day after the Campbell's statement before the Hague war crimes tribunal before which Taylor is accused of war crimes, are the diamonds in the South African police appeared.

13 years under lock

A trustee of the Nelson Mandela Children's Foundation, Jeremy Ratcliff has passed the ominous stones on Thursday, the South African police. Ratcliff confirmed in obtaining the three small stones in front of over 13 years ago by Naomi Campbell to have. Campbell wanted to donate the stones of the Children's Foundation. He was suspicious but the stones were so Ratcliff. He had suspected even then that it could have been a so-called blood diamonds. And do not bring to the Nelson Mandela Foundation with a donation in such disrepute that it had decided to keep the stones easily with you - now a total of 13 years. According to the testimony of the British top model Naomi Campbell at the Hague war crimes tribunal, he then decided to hand over the stones to the police.
Taylor or not?

Campbell had admitted in court on Thursday, 13 years ago after a charity dinner in South Africa to have received three diamonds, from unknown men who knocked on their hotel door at night. Whether the stones, as the prosecution of the tribunal suspects of Liberia's ex-dictator Charles Taylor came, who was then at the dinner also a guest, Campbell could not say definitely.
Allegations before war crimes tribunal

The prosecution in The Hague wants to show Campbell's statement that Charles Taylor has owned diamonds. The diamond is said to have obtained in the course of arms deals by the rebels in Sierra Leone. Taylor is accused of war crimes tribunal to have with weapons in the bloody civil war in its neighboring country of Sierra Leone supported the rebels active. Taylor is accused of war crimes and crimes against humanity.
