According to the editor, the news of the discovery of giant diamond mines has caused fears in the industry. The quality of diamonds and the amount of diamonds have a direct impact on the supply and demand of diamonds in the world. If a large number of gem-quality diamonds enter the market, the current price system of diamonds will inevitably be affected. The rarity and preciousness of diamonds will also follow. The "China Gold News" reporter conducted an in-depth follow-up on the origin of this news. The investigation found that the so-called "trillion-carat carat diamond mine" has many doubts: the reserves are unknown, the naming is wrong, the concept is vague... Which one is the trick? Or artificial hype? â– Event direct hit: Recently, the British "Daily Mail" published a message that Russia recently announced a crater called Popigai discovered in the 1970s, with a diamond mine. Located in a crater more than 100 kilometers (60 miles) in diameter in eastern Siberia, the mine is estimated to exceed teraflops and meets the 3,000-year global gem market demand. Once the news was revealed, it was reprinted by many media, which triggered an uproar in the jewelry industry, especially the diamond industry. Many people are beginning to worry that if this news is true, it will inevitably have a huge impact on the diamond industry. In addition, the world rough diamond market has been declining since the fourth quarter of last year. Once the news spread, it will add to the diamond industry. In order to convey the correct industry information, the reporter interviewed some professionals and corrected the misunderstandings in information dissemination. The picture is ambiguous: It is not stated that there is a picture in the article "Daily Mail" with large diamonds . In the picture, a hand holds a few large-grain diamonds. Many people misunderstand the large production of this Perpigh diamond mine. Granular diamonds. But in fact, a closer look at the picture shows that it is not difficult to tell that each of these diamonds over 50 carats belongs to the Yakutia region. The picture only points out that the scale of the Yakutia diamond mine cannot be combined with the published Pippa diamond mine. Comparable. Liu Houxiang, chief representative of China's HRD Antwerp China Council, believes that the diamond mine formed by the “Meteor Impact†is unlikely to have large-grain diamonds, which should be “particlesâ€. He explained that there were diamonds that had been found in craters before. No large-grain diamonds were found, and according to the law of diamond formation, large-grain diamonds could not exist after being impacted by meteorites. Liang Weizhang, director of the Chemical Inspection and Appraisal Office of the Guangzhou Entry-Exit Inspection and Quarantine Bureau, told reporters that in his information, the diamonds in the pebbles of the Perpignan were actually discovered before the 1970s, but the large-scale study is from 70. At the beginning of the decade, the geologists were initially attracted simply because it was a crater caused by meteorites hitting the Earth 35 million years ago. Later, during the slicing of the meteorite samples, many very hard particles, diamonds, were discovered. Liang Weizhang believes that it is possible to have diamonds in the crater. The tremendous pressure and high temperature caused by the impact of meteorites can convert graphite into diamonds, but other conditions are needed to convert into gem-quality diamonds. Liang Weizhang told reporters that the materials he has in his records indicate that the diamonds in the pebbles of the Perpita are small-grain diamonds, mostly less than 10mm in diameter and 0.5mm~2mm in thickness, most of which have a black or gray appearance, regardless of size or appearance. Not suitable for jewelry. The reserves are not proven: "Decryption" is being questioned. At the same time, Liu Houxiang also suspects that the reserves of the Perpigh are really as much as reported. The original translation of the Daily Mail is as follows: "Scientists estimate that there are trillions of carats lying under a crater hit by an asteroid 35 million years ago in Siberia, which is more than 10 times the current global reserve." It is not difficult to see The so-called reserves are only estimates of scientists and have not been confirmed. Liu Houxiang also believes that the real reserves are still "waiting for further exploration." He also reminded the industry that news about Russia's announcement of diamond mines is worth noting. At present, Russia's largest state-owned diamond mining company, Alrosa, is planning to privatize and enter the capital market, taking into account the use of this news by Erosa. The possibility of speculation. A jewellery practitioner also said that "this report of the Daily Mail is to cooperate with a soft news that Erosa listed on the GEM, and I don't know why it will cause such a big response in China." It is worth pondering that the "Daily Mail" specifically mentioned that "the former Soviets have also been producing a variety of synthetic diamonds, the industry has proved to be lucrative", this short paragraph is above, "The Kremlin from 20 Since the 1970s, it has been known that there may be huge reserves of diamonds in this crater, but at that time, because diamonds were already a high-margin industry, the diamond market was strictly controlled. In order to avoid affecting the entire industry, this discovery has been kept secret. "The following is," the government finally gave the information of geology and mineralogy of the Novosibirsk Institute to the public through a press conference last weekend. But Liu Houxiang sneered at the reasons for keeping the "diamond" mine secret. It is unreasonable to think that Russia has kept the "diamond" mine secret for so long. Liang Weizhang is more cautious in facing this problem. When he comes to see if there is news hype, he still needs to see the mineral rights of the Perpigne mine. At present, the mineral rights of the Perpiga diamond mine are still inconclusive. If it is really hype, there will be a series of operations in the follow-up, there will be new relevant news, and the industry may wish to actively pay attention and carefully distinguish. Liang Weizhang analyzed that scientists' research on Perpigue was concentrated in the 70s and 90s of the last century. For such a long period of time, relevant information has not been paid attention to, because on the one hand, the diamond particles and color purity are not exhausted. As expected, Russia may have always believed that geological research in this area is more important than research on diamond ore. Although academic research materials have been published along with other research materials, they have not been officially released, so there are fewer people. On the other hand, because of the difficulty in mining, the input-output ratio of mining is difficult to predict, so it has not been taken seriously. According to Liang Weizhang, even if it is used as an abrasive for industrial use, the cost advantage of the Pippe diamond is still difficult to accurately compare with the synthetic industrial diamonds that are now quite mature. In addition, Perpigh is located in the extremely cold Siberian region. The diamond is scattered in a vast area of ​​100 kilometers, but the particles are smaller than the sesame. The mining difficulty can be imagined. Therefore, under the huge mining cost, the quality of the diamond produced is Not high, the input-output ratio is a factor that must be considered, and may also be a reason for Russia not to open and exploit the Perpigh. Inaccurate naming: Actually , the original volume of industrial diamond "Daily Mail" mentioned that these estimated reserves of more than one trillion carats can meet the needs of the global market for 3,000 years, but in some reprints, they were misrepresented. To meet the needs of the global gem market for 3,000 years. In fact, the diamonds produced in Russia's Perpigne diamond mine are only industrial diamonds, mainly used in high-precision scientific and industrial markets, non-gem diamonds. The original stone of a diamond is a rough diamond, also known as diamond, which is divided into industrial and non-industrial (generally referred to as gem-quality). Gem-grade is generally the diamond that our consumers usually call, and the clarity is generally higher. Industrial diamonds, also known as industrial diamonds, are the same as the main components of gem-quality diamonds. They are carbon crystals and industrial diamonds. Usually the quality is poor. Consumers who see Chinese-reported diamonds naturally associate with gem-quality diamonds, causing certain industry panic. At the same time, Liu Houxiang also suggested that if this report is true, and eventually the Perpigh diamond mine really has such a large reserve, it will have an impact on the jewelry market, but this effect is also indirect, not direct of. He analyzed that once the large industrial diamond reserves are mined, it will inevitably lower the price of industrial diamonds, which will affect the industrial diamond synthesis producers, and they will turn to synthetic gem-quality diamonds, which will affect the jewelry market. But this indirect effect is clearly inferior to the direct impact of the discovery of a gem-quality diamond mine that can supply 3,000 years, so the jewelry industry does not need to panic. In an recent report, Rapaport, the authoritative industry media that publishes diamond prices and market information, pointed out that it is still too early to talk about the status of the Pippi's diamonds. The impact products found so far. It is not suitable for making jewellery, so it is impossible to discuss its impact on the world diamond market and price. The concept is vague: Is it a "harder"? According to the translation of the Daily Mail, the Pipiga diamond in Siberia is twice as hard as ordinary diamond, making it ideal for high-precision scientific instruments and industrial applications. In response to this formulation, Liu Houxiang said that the hardness of diamonds has been 10 so far, and no material that is harder than diamonds has been found. Therefore, there is still some doubt about the hardness of twice as much as ordinary diamonds. In the English manuscript of the Daily Mail, it is only mentioned that it is twice the hardness of the ordinary "gemstone", and the true meaning of "gemstone" is a gemstone, not a diamond. This vague statement once also puzzled the insiders. : Diamond hardness is twice as normal as other kinds of gemstones. Is this the Daily Mail? Or is it really twice the hardness of a diamond? In response to this problem, Liang Weizhang provided reporters with more direct information: The Daily Mail article was derived from the news release issued by the Tass news agency at noon on September 16, and the press release has a clearer description of the diamond hardness: In the 1970s, former Soviet scientists discovered the first super-hard "diamond" produced by Perpigue, which has an unusual structure and twice the hardness of ordinary diamonds, and has a large reserve. It is confirmed that the diamond hardness produced by Perpigue is twice as high as that of ordinary diamonds. As for why, Liang Weizhang believes that further research and analysis is needed, and it is not yet possible to make an evaluation. Regarding why this has not been said, the Tass newsletter stated that this was “decryptionâ€, that is, “confidentiality†was carried out in the past. The reason was that the former Soviet Union was developing synthetic diamond technology, so the research data of Perpigue was kept secret. In the news article of the Tass news agency, experts also claimed that Russia has the only resource of superhard materials from the world's unique outer space source. Although the size and aesthetics of the diamonds currently discovered in the Perpita Mine are not optimistic, mining is difficult, but Liang Weizhang also admitted that with the further study of Perpigue, it is uncertain whether more valuable diamonds can be found. If official information reveals more valuable industrial diamonds, it may also have a significant impact on the industrial diamond market. As for the production of diamond by Perpigue is twice the hardness of ordinary diamonds, it is a direction worth studying, but the status quo cannot be ignored. At present, ordinary diamonds are enough to meet the hardness required for cutting or drilling, if it is twice as common. The hardness of the Pippe diamond with diamond hardness is deeper.
