Be engaged in gem working to also calculate quite long, many friends had said to me about diamond the word that is the sale fraud and so on with 20 the oldest centuries, also have on the network many such article, some authors return ego even nominal " deepness good article " , " conscience uncovers secret " , be really such? If you were believed, you are too then innocent! Idle comes to happen to today without the thing, write a little article to say his notion, and throw those profound, as dry as a chip data, theory completely at the same time, use only simple " person word " talk about basic common sense, seeing diamond after all is a fraud.
The person that will see those fraud talk first people argument:
1, diamond is the crystal that carbolic element makes nevertheless, just following black lead essentially is one and the same; 2, diamond reserve is substantial, thing is not rare ought not to expensive; 3, diamond is Daibiersi of forestall, also Daibiersi goes to the price on hype; 4, synthetic diamond can replace diamond completely. To prove these thesis, the article listed much data, very much even chemistry is academic, appear scientific and rigorous, have conviction extremely, fact of feeling letting a person is such, be really however such?
Our one by one analyses below:
One, what is diamond?
Right, diamond is formed by carbolic element, carbolic atom union comprised diamond, seeing diamond from chemical angle is carbon only really, but does it follow black lead really same? Jest! The formation of diamond the condition differs completely with black lead, diamond is in 5- - 70 thousand atmosphere, 1200- - form below the natural condition of 1800 Celsius at the lithosphere deep 70 kilometers are the following, by carbolic atom the instant crystallizes and become. In the mine that extracts at present, the period that most diamond forms is to be 3.4 billion years ago with 12-18 between 100000000, be called so the oldest gem on the world. Celestial or heavenly body is opposite outside the high temperature of the earth that bumps generation instant, high pressure, also can form diamond. The formation of diamond is not in one day, all previous changes via earth of several years formed the diamond that we see now. Although carbolic atom is formed, but it and it is the black lead that carbolic atom forms does not have same physics feature together, diamond is only volume is highest hardness, strong refractive index, high in nature chromatic dispersion is worth the gem at a suit, its hardness is 10, it is the corundum hardness of 9 than hardness hundreds of times taller; The igneous colour of diamond is proper, shine and downy, shi Shan of rutile of both neither resembling, Mo Sang gets offending to the eye, wait for gem than ruby, sapphirine again strong, if say to learn to be the same as into split phase with graphitization should cheap, be the black lead Xi that carbolic atom forms likewise so why is price higher than gold? Besides, carbolic atom forms " diamond " crystal can not call diamond certainly, only colored, clean degree, piece degree arrived lapidary level ability calls diamond, can be diamond only otherwise; Same, red, sapphirine is alumina nevertheless, can why is price of ruby, sapphirine so expensive also?
2, how many does diamond reserves have?
The person that fraud is talked people think consistently, diamond reserves is tremendous, tellurian diamond is gotten more exhaustless, if allocating an individual each a few about a hundred carat is no problem, all on certain even heavenly body is diamond, raining repeatedly is stone of run the drilling tool into the well, content with rare for expensive, since diamond reserve is so large, that should not be worth so much money.
Diamond is general in Bai Liyan of consist in gold and porphyry of potassium magnesian brilliant, erupt to be taken by magma through volcano to the earth's surface, so diamond mine has two kinds of kind, was formed of ejective ground by magma secondary mine, through taxing the means mine that get; And was not extracted by the means that uses mining of ejective ground, now basically is former exploitation laying mine. Eye has ore deposit of 41 countries diamond on preexistence bound, among them 90% what the country such as Australia, Russia, Zaire, Botswana, south Africa holds whole world output. According to already the reserves of ascertain, 2.5 billion carat is shared on the earth, press existing exploitation level to extract quite 25 years, but as level of science and technology rise, can find new diamond ore deposit probably. But, even if can find new ore deposit, can be the price of diamond reduced? Does the exploitation cost of diamond have many tall are you built? Take the biggest diamond pit Russia on the world " peace " for diamond mine, since go up century 50 time the first batch of diamond from " peace " after be being come out by mining in diamond mine, up to now Russian collier already from the gouge in this mine the rock of 165 million stere. This pit diameter about 1600 meters, deepness amounts to 533 meters, helicopter also is prohibited from had flown above it, the air that because of this large hole creates swifts current engulf of enough general helicopter its interior. This shows, go up from this earth " the biggest burrow " in mining diamond is not an easy thing apparently, so, resemble character of place of the person that fraud is talked, diamond is completely on some heavenly body, if we go extracting on some heavenly body, how is that exploitation cost met?
Daibiersi forestall be is global diamond produced and sold?
We see Daibiersi first is how of get rich: Dai Bier's brother bought next farm 1860, sell to the Englishman brother cleans out Luo Deci later auger, because the government regulates every mine at that time advocate exploitation limits is 30 feet only, after digging certain deepness so, cannot continue to extract, brother of Er of collect at present buys the mine of photograph adjacent come down, limitation cancelled 1876, brother of Er of collect at present incorporates ceaselessly other company, establish Daibiersi formally 1888 to combine mining industry company. In an initial period, daibiersi really forestall the diamond mine of the whole world and sale, but later, its monopoly position is challenged stage by stage, russia, Australia, Canada all discovered diamond mine, and should controlling these national diamond completely to produce is day of square night simply talk (resemble oil, the oil to the whole world produces Ou Peike to mastering very great speech to counterpoise with the sale, but the oil that says Europe admire captures complete forestall whole world, also rather too trifling matter) .
The person that fraud is talked still thinks, be Daibiersi " diamond constant is ages ago, one always circulates " sale binds diamond and love in together, make diamond represented love, but in fact, it is diamond not just, on the history, what a lot of gem such as ruby, violet brilliant ever were acted according to to be love is indicative, does that serve as what is there so for advertisement incorrect? And diamond serves as the advantage that there is other gem to be able to not be rivalled really for gem.
4, can synthetic diamond replace natural diamond?
The person that fraud is talked says, the lubricious step with synthesize diamond to having better than natural diamond and spend completely, and cheaper price, can replace diamond completely so. We see diamond first is how complex. The synthetic method of diamond basically has two kinds: One kind is CVD law, one kind is HTHP law, but no matter which are planted,the method is not an easy thing. The United States, before the country such as Russia, China, Japan ever cost financial resources of huge manpower material resources to study diamond synthesizes a method, the country that can master diamond to synthesize a technology at present also a few, of the others all is synthesis a few industrial diamond, cannot use as at all lapidary. Remove 10 thousand conditions, technology of diamond of even if synthesis arrived very adult rate, synthesizing diamond to want to replace natural diamond also is one's own wishful thinking, we saw ruby know the synthetic technology of ruby is very mature, ruby of a natural and high grade columbine blood red the price of one carat tens of thousands of go to ten yuan, and the synthetic ruby of coequal grade one carat just ten money, why to synthesize ruby to cannot replace natural ruby? This showed natural gem to be remained in the memory of people precious, rare some, valuable, and this was not to synthesize what gem can replace. Can use as gem into diamond so, OK of course, daibiersi had rolled out the special brand gem that synthesizes diamond, 1/3 what the price is natural diamond only, but this still cannot say to synthesize diamond to be able to replace natural diamond.
So by what the price of diamond is decided? The market decides the value! The price of diamond still is decided finally by the market, gem market increases continuously to the demand of diamond, so the price of diamond also is relatively stable. Old WJ ever was in " century fraud " the article is pleasant to the eye, the diamond cost price of 1 carat also with respect to 300 yuan of RMBs, the value that does not know these 300 yuan of RMBs is how of numerate, I know only is to extract cost also is counted this not merely merely, the cost plus cut burnish, cost of appraisal, want to know, present artificial so expensive, build even unskilled laborer everyday salary also gets 200 yuan. Why is that met is somebody written " deepness good article " ? I had the honor to read a few, discover a clew eventually, a word is mentioned repeatedly in having an article " Mosangshi " and also mentioning Mosangshi for many times in the comment is better than diamond, igneous colour strong, hardness is tall, low-cost, if replacing diamond to make jewelry, do not look completely, immediately I understood, this popularizes Mosangshi one piece namely " flexible language " , just, shi Yike pulls the Mo Sang with synthetic so mature technology to also want hundreds of, is one carat less than natural diamond are 300 yuan how of numerate?
