"Man-made diamonds" are almost too hard for the real thing on the mark
Noble and brilliant Diamond Can be said to dream of every woman's accessories. But its expensive price Queshi discourage most people. Today, however, clever scientists have been able to produce relatively inexpensive "artificial diamonds," which even the experts make it difficult to distinguish between true and false diamond appreciation.
Leo is a bald man, his English with a thick Israeli accent. Identify the authenticity of diamonds and diamond valuation to be his "champions." At this point, he is a New York jewelry store diamond trading range as a guest identification of three small diamonds, each weighing less than one carat: one is pink; one is transparent, no color; have a is light green.
Leo proficient with the index finger and middle finger inside out sinking, pink diamond, put it gently on the glass case? On careful observation through the eyepiece as well as reflective diamond clarity diamonds , the shape and cutting surface. He used the same methods that can identify the other two diamonds. Then he put down eyepiece, said slowly: "They are really, quality is not bad. If there is another big point diamond, come back here, I will give you a good price."
Leo Diamond appreciate the ability and experience is after years of diamond trading and cumulative. But he never imagined his "sterling reputation" How many pieces of man-made diamonds actually defeated on. In fact, Leo How many pieces of that just to identify a small diamond is a laboratory in Boston, spent a few days and created the "man-made diamonds", not the crustal movement over millions of years to form a "natural diamond." The guests who are only the United States, "Newsweek," a reporter, he only wanted to try the man-made diamonds "indistinguishable" to the extent where. How many pieces
this small man-made diamonds are distributed by the "charm" even greater than that Leo the veteran was brutally "Waterloo" in the diamond trading range of several other jewelry connoisseurs have taken the bait. Chemtov is the owner of a jewelry store in the area, How many pieces of this man-made diamonds closer look at him, looked for a long time later, said: "How much do you want?" Another jewelers diamond connoisseur Alex Brooks carefully observed after artificial diamonds, very definitely, said: "not. They are not artificial."
Weight 88.88 kt of pristine natural diamonds, worth about HK million in 4200-4800 between the High temperature
generate artificial diamonds In the end the scientists what "magic" can create almost the same as natural diamonds, synthetic diamonds? Currently in the lab, there are two ways to create artificial diamonds. "Apollo Diamond" is a Boston company that has developed a diamond in the manufacture of high-voltage device in the method: In a high pressure, such as dishwasher-sized device, the use of chemical gas phase deposition method to heat and hydrogen gas Then it will produce a carbon plasma; plasma will then be the same as the rain lies here and at the bottom of the carbonation of high-voltage substrate layers. Plasma piled up, and slowly harden, and finally the formation of crystals like diamonds.
Another method of making artificial diamonds is located in Florida Gemesi Corporation (GEMESIS) developed. High temperature and high pressure is still a key manufacturing technology. In a ceramic container, the hydraulic machine can provide high pressure, but the electric heat can produce. In the high pressure and high temperature state of the carbon crystal. It actually provides a simulation of the formation of natural diamond in the earth's crust in the environment. In addition, it allows people excited is Gemesi companies are selling colored by its production of artificial diamonds, including the extremely rare yellow diamonds and blue diamonds. It now produces more than a week to a total of 100 karats of diamonds. And the price is relatively lower natural diamond. For example, the price of synthetic yellow diamond is about 4800 U.S. dollars one carat.
Apollo Diamond company also plans to launch this summer, colored and colorless diamonds. The price may be lower than natural diamonds, one percent to three percent. Experts believe that, despite the production of synthetic diamond instruments are very expensive, but compared to a diamond mine or mining to be much more cost-effective.
Difficult to be replaced natural diamonds
Face man-made diamonds "invasion", the surface of natural diamond vendors pretending to be calm and hegemony that natural diamonds will not be replaced, they still can not help a bit worried, fear cheap and good Artificial diamonds away their customers.
Many people think that natural diamond is expensive mainly because it is extremely rare and need to go through the cumbersome process multi-channel can be "published." Yes of course people think so. Little did they realize the price is actually a natural diamond merchants is behind the "trick." In fact, sapphires and rubies rare than diamonds, thousands of times. But why their prices are better than diamonds low? Mainly because several of the world diamond sales giant diamond in the strictly controlled production.
Five diamond mining companies in the world including South Africa's De Beers (DEBEERS), Russia's Alrosa Company (ALROSA), Israel, Levi Scott Company (LEVIEV), Australia and the Australian RIO BHPBILLITON TINTO. According to the American authorities report (RAPAPORT DIAMONDREPORT), these companies control 90 percent of the world diamond market share. The South African De Beers is the first of five. It is the world's largest diamond mining business. In addition, the "diamonds are forever" slogan phrase deep impression is that it's a masterpiece. Moreover, the De Beers diamond sales in order to further promote, launched a fierce advertising campaign, the Diamond is defined as "a symbol of love." In the United States, the diamond sales in the 85% is used as a gift.
However, if those in the laboratory-made artificial diamonds really a market capitalization of 60 billion influx of natural diamond market, the consequences of what will happen? Washington's Carnegie Institute of Technology scientist Robert said: "If man-made diamonds are really a lot to enter the market, so the natural diamond industry may collapse."
Natural diamond vendors, but this was dismissed. Chief Executive Officer of De Beers marketing Stephen. Loessl that, according to a survey company, 94 percent of women will choose to "natural diamond" instead of "man-made diamonds." Scientists may think that the chemical properties of synthetic diamonds and natural diamonds with the same appearance. But Loessl said: "They (man-made diamond producers) do not even understand a natural diamond on a pair of lovers, or couples the meaning implied
