1. Some economists believe that the price of diamonds has been artificially raised, which is not determined by the supply and demand of the market. It is natural for monopolists like De Beers to play with the price of diamonds. Since its inception in 1888, De Beers has become synonymous with diamonds. De Beers also assesses diamonds and sells most of the world's uncut diamonds to diamond cutting centers, which cut and grind these diamonds for jewelry. De Beers is the leader in the global diamond mining instry. It operates 19 diamond mines in the world and proces more than half of the diamonds in the world. The diamonds mined from these mines and the diamonds obtained from other channels are all sold by De Beers' London based centralized sales organization< In fact, the U.S. Department of justice once sued De Beers for monopoly crimes. Now, the company's top executives generally dare not set foot on the U.S. territory, otherwise they may receive a subpoena from the court at the airport. It is undeniable that De Beers does control the market price of diamonds by controlling the supply of diamonds. De Beers only allows 125 jewelry cutting companies to buy diamond raw stones directly from them. All of these 125 diamond cutting companies are customers of the unified sales organization of De Beers center. People in the instry call them "De Beers 125". Every year, De Beers' central unified sales organization holds 10 diamond appreciation activities to sell uncut diamond raw stones to its customers. Meanwhile, De Beers' central unified sales organization often keeps close contact with the world's major diamond cutting centers. The selling price is entirely determined by one side. De Beers sells diamonds together. Diamonds of different sizes and qualities are put in sealed plastic bags with a price tag on them“ De Beers 125 has no right to bargain. They can only decide whether to buy or not. Only when the weight of a single diamond is more than 10.8 carats, can there be extremely small bargaining space. De Beers actually controlled the price of diamonds from the source

in the past, some small companies tried to sell their own diamonds, but they were madly retaliated by De Beers. The method of retaliation was very simple. As long as De Beers asked its central unified sales organization to release a large number of diamond reserves in a short time, the price of diamonds would drop sharply, and small companies could not afford such a price war. Now, however, some diamond miners are beginning to compete with De Beers. These companies mainly concentrate on drilling in Africa, Australia and Canada, and their business is booming day by day. All the diamonds cabenkir bought in Angola were sold to an Israeli Diamond tycoon who started 30 years ago. Now the diamond dealer has completely shut De Beers out of Angola, and has begun to threaten De Beers' traditional control over Russian drilling. In order to regain its absolute monopoly position, De Beers began to enlarge the trading volume again. From 1999 to 2000, De Beers suddenly launched a diamond inventory worth 5 billion US dollars to the market. The market price dropped sharply, but did not completely collapse. This proves that the relationship between supply and demand can still restrict the price of diamonds, At the same time, De Beers' competitors are growing up. De Beers himself tasted the bitter fruit of arbitrary price manipulation. In 2000, the company faced the problem of insufficient supply of raw stones and had to start its emergency reserves<

global attention to "blood diamonds"
diamonds are associated with blood and war at many times. As early as in ancient times, tribal leaders in southern India fought for the ownership of diamond mines there and launched the most tragic civil war in Early India. The most famous diamond war is the civil war in Lebanon between 1970 and 1980, which was secretly financed by Lebanon's dealers and Sierra Leone's diamond smugglers. In the 1990s, the civil strife in Angola was still caused by diamonds. Jonas Savimbi, a diamond tycoon in Angola, formed his own army to fight against the government in order to seize the diamond rich areas in the country. In 1992, Jonas Savimbi and the government reached a cease-fire agreement. In the following seven years, he employed more than 100000 semi slave diggers to work for him. The total value of diamonds mined in the seven years was about $4 billion. There are also some African rebels who use the bloody means of civil war to seize the diamond procing areas, illegally exploit and sell rough diamonds that are unprocessed or simply cut and only partially polished to raise military expenses. The diamonds flowing into the market from their hands are called "blood diamonds". Now the international community has launched the Kimberley Process international certification scheme for rough diamonds, which has been officially implemented in 39 countries and regions, including China. This system stipulates that the exporter must issue an official certificate for the exported rough or semi-finished diamonds, indicating the value, quantity, weight and grade of the diamonds. Only after the importer has verified that the official certificate of the exporting country is correct, can it be allowed to import.
