Henan Synthetic Diamond Industry Upgrading

"Diamonds are forever, one piece will last forever", the advertising slogan of the diamond brand Debeers has become the reason why many Chinese people are willing to pay for diamonds. However, Debeys, who started with natural diamonds, has also opened up a new brand Lightbox, selling a kind of "laboratory-grown diamonds". Henan is a province with a large production capacity of synthetic diamonds. In fact, some companies have entered the field of "laboratory-grown diamonds" long ago and have become suppliers of synthetic diamond rough.

In addition to being able to make jewelry comparable to natural diamonds, synthetic diamonds can also be used in semiconductors, medicine, cosmetics, etc. by using their characteristics in sound, light, electricity, and heat. For Henan, a province with a large production capacity of synthetic diamonds , The conversion and upgrading of new technologies and new processes will open up space for downstream applications for these enterprises.

Brilliant "laboratory-grown diamonds" produced in Henan

A one-carat natural loose diamond, if the color, clarity, and cut are not bad, the price can reach more than 100,000 yuan. However, at VINKKI Jewelry Experience Store on Zijingshan Road, Zhengzhou City, the price of a one-carat diamond of the same quality is only 50,000 to 60,000 yuan.

“The diamonds we sell here are all laboratory-grown diamonds. They have the same physical properties, chemical composition, and crystal structure as natural diamonds. They also have diamond identification certificates issued by authoritative testing agencies such as GIA, IGI, and NGTC. They are not zircon or diamonds. Moissanite.” The person in charge of the VINKKI jewelry experience store said that in addition to colorless diamonds, there are many varieties of laboratory-grown diamonds such as yellow and blue.

The cultured diamond technology originated in the 1950s. After more than half a century of scientific research, artificially cultivated diamonds have only reached the market level in terms of quality and cost. Laboratory-grown diamonds are still a blue ocean in the jewelry industry. The well-known natural diamond brand Debeers also launched the laboratory-grown diamond brand Lightbox in June this year, specializing in the sale of laboratory-grown diamond jewelry.

However, many people may not know that many of these brilliant laboratory-grown diamond roughs are actually produced by Henan artificial diamond enterprises.

Industrial companies enter the diamond fashion consumer market

There is a saying in the synthetic diamond industry: the world's diamonds look at China, and China's diamonds look at Henan. Since the establishment of the "Three Grinding Institute" in Zhengzhou in 1958, the agglomeration of Henan's superhard materials industry has continued to increase. Under the background that China's superhard material production accounts for 90% of the global total, Henan's synthetic diamond production has accounted for 80% of the country's total, becoming the world leader.

Through the world's leading technological advantages, Zhengzhou Huajing Diamond Co., Ltd. (stock abbreviation: Yu Diamond, stock code: 300064, hereinafter referred to as "Huajing") has been able to cultivate colorless diamonds with high purity and very rare diamonds in nature. colored diamonds.

As early as November 2016, Huajing issued 527 million additional shares and raised 4.567 billion yuan for the annual production of 7 million carats of gem-quality diamonds. At present, a total of 1.845 billion yuan has been invested in the raised funds. The equipment of the first phase of the project has entered the production stage, and part of the main workshop of the second phase of the project has been completed.

For the laboratory-grown diamond market, Liu Yongqi, the general manager of Huajing Company, is very optimistic. According to the 2016 Diamond Industry Analysis Report by Deberes, China, the United States, India and Japan have been promoted to the world's four major diamond consumer markets. The total demand accounts for 73% of the global total. Among them, the millennial population is close to 1 billion, of which more than 220 million people have reached a level of affluence and are active consumers of diamonds.

"Light luxury fashion and independent personality have become the positioning of cultivated diamond jewelry, which is very in line with the consumption demands of the millennial generation. In addition, more and more brands have entered the artificially cultivated diamond market, so that the demand for artificially cultivated rough diamonds has grown rapidly." Liu Yongqi told Henan Business Daily reporter, Huajing cut into the rough supply of artificially cultivated diamonds, and entered the diamond fashion consumer market through cooperation with brands.

The high value-added outlet for synthetic diamond is not only the artificially grown diamond market, but also has many application scenarios in many new materials.

"Previously, artificial diamonds were mostly used for their high hardness. In fact, artificial diamonds have also begun to be used more and more in sound, light, electricity, and heat." Liu Yongqi said that Huajing has obtained Cooperate and sign a cooperation framework agreement to expand and enhance the application of diamond materials in the fields of optics, semiconductors and new energy through the joint construction of the "Huajing Diamond Laser Application Engineering Center".

In many daily use scenarios, Huajing has also found the application scenarios of artificial diamond.

In the first half of 2018 alone, Huajing obtained patents including anti-hair loss shampoo containing nanodiamondene and its preparation method, comprehensive functional toothpaste containing nanodiamondene, Chinese herbal toothpaste containing nanodiamondene, nanodiamondene Oxygen 3D printed bone and its production method, etc.

"Taking nanodiamondene 3D printed bone as an example, this technology can add a layer of nanodiamondene to the surface of 3D printed dentures, and use the anti-inflammatory effect of nanodiamondene to make implanted dentures more comfortable to wear." Liu Yongqi said that with many functions such as whitening, anti-aging, and pore improvement, the future of nano-diamondene in the cosmetics industry is limitless, and Huajing will also gradually transform from an artificial diamond synthesis enterprise to an artificial diamond new material in the future. Production capacity seeks space for downstream applications.
