Xinhua News Agency, Zhengzhou, February 14 (Reporter Wang Zichen, Shi Linjing) Recently, the reporter visited China's artificial diamond research and development production and gathering area in Henan Province and learned that China's artificial diamond production industry has a strong technical base and capacity advantages, the industry believes this It is an opportunity for the transformation of new and old kinetic energy in the industry. Diamonds made in China are expected to reshape the global industry in the future.
“Artificial diamonds should start from its original stone – synthetic diamond. China has independently developed and manufactured synthetic diamonds in 1964. By 2017, China’s production capacity has been ranked first in the world for more than a decade, accounting for the world’s total output. More than 90%." Liu Yongqi, general manager of Zhengzhou Huajing Diamond Co., Ltd. said.
On January 30th, at the Diamond Brand Experience Center of Zhengzhou Huajing Diamond Co., Ltd., the staff displayed artificial diamond jewelry.
As one of the largest artificial diamond manufacturers in China, Zhengzhou Huajing produces 2 million to 3 million carats of gem-quality diamonds (ie artificial diamonds). The current annual production of 7 million carats of gem-quality diamonds has also been partially put into production.
Hu Junheng, manager of another large artificial diamond company in Henan Huanghe Cyclone Diamond Division, said that before the advancement of artificial diamond technology to the consumer sector, it was widely used in aerospace manufacturing, petroleum exploration, electronic chip and other scientific and technological industries, which also allowed domestic hatching. A lot of companies.
This is the grinding workshop of Zhengzhou Huajing Diamond Co., Ltd., which was shot on January 30. The workers are cutting and grinding rough diamonds.
“Artificial diamond is an industrial synthetic drill, also known as cultivating diamonds or growing diamonds. It is the principle of simulating the growth of natural diamonds, allowing carbon to be produced in a high temperature and high pressure environment.†said Chuan Yiyi, an associate professor at the Physical and Chemical College of Henan Polytechnic University. A common analogy, the difference between natural and artificial is like the difference between ice in a river and ice in a refrigerator."
This is not a statement. In 2018, the US Federal Trade Commission revised the definition of "diamond." The diamond industry guidelines, published in the US Federal Register, read: "According to changes in the market, the final version of the guide removed the word 'natural' from the diamond definition because it was made in the laboratory and has the same optics as the mined diamond. Products of physical and chemical properties are also diamonds."
This is the production workshop of Zhengzhou Huajing Diamond Co., Ltd., which was shot on January 30. The six-face press is operating under high temperature and high pressure.
In the same year, De Beers, who had long occupied a monopoly in the industry, changed his mind that artificial diamonds were not diamonds or fake diamonds, and began to actively sell artificial diamonds.
Paul Jinniskey, an independent analyst in the diamond industry in New York, told reporters: "The vast majority of industrial diamonds in the world are made in China, and the annual production capacity is about 10 billion carats. The diamond supply for international jewelry use is now There are only a few million carats per year. Even a small fraction of China's production capacity is upgraded to diamonds used in jewelry, which will greatly affect the international diamond supply."
The news that De Beers began selling synthetic diamonds also caused shocks in the Chinese industry. They said that this is a huge boost to the artificial diamond industry, which is objectively conducive to the accelerated development of artificial diamonds in China. "From the current sales data, the positive has already appeared, the sales of artificial diamonds in the last quarter of 2018 increased significantly." Hu Junheng said.
This is the grinding and drilling workshop of Zhengzhou Huajing Diamond Co., Ltd., which was shot on January 30. The workers are operating the automatic edger.
Liu Yongqi believes that this industry is mainly based on the original stone for the production of synthetic diamonds, but many enterprises have expanded the industrial chain to form a diamond-wide industrial chain with raw stone production and processing services such as grinding and inlaying.
“The quality of artificial diamonds produced in China is progressing very fast,†said Paul Jinnischi.
“Cultivating diamonds has become unstoppable in the jewelry market because of its unique advantages.†Chuan Yiyi said that whether it is from price or mining protection, cultivating diamonds has the incomparable advantages of natural diamonds.
On January 30, in the grinding workshop of Zhengzhou Huajing Diamond Co., Ltd., workers were showing loose diamonds.
Some experts said that the current timing of shaping the image of artificial diamonds and cultivating consumer concepts, if seized opportunities, will break the monopoly of foreign investment in diamond supply and reduce the pressure on diamond consumption of consumers, especially young people.
“At present, the entire international consumer market is still in a process of accepting synthetic diamonds. Consumers’ awareness of artificial diamonds is still scarce. It is necessary to continuously popularize artificial diamonds to the public in terms of news reports, public opinion guidance, and advertising regulations. Relevant knowledge, eliminating the blind spots of consumption." Yu Chuanyi said.
