"Fire" excellent large-grain artificial cultivation of diamonds for the Yellow River Group Diamond Division
"Diamonds are long-lasting, and one is forever." This classic advert highlights the preciousness and dignity of diamonds, but the high price of diamonds has discouraged many people. Recently, the international online Henan channel came to the artificial diamond base in Changge, Henan. At present, the mature high-tech synthetic diamond technology makes diamond jewelry gradually become a popular gem that ordinary people can own and wear.
With the development of science and technology, industrial synthetic synthetic diamonds began to enter people's lives. The Yellow River Group in Changge, Henan Province successfully developed large-grain synthetic diamonds in 2005. In recent years, it has successively developed colored diamonds such as yellow diamonds and blue diamonds, and even developed “life source†diamonds. The production process has also achieved intelligence. Chemical.
In essence, diamonds are minerals, which are often referred to as diamonds. They are a kind of "stone" composed of carbon and the hardest substance naturally occurring in nature. For example, human hair contains carbon components, which are specially treated to extract the carbon from the hair, and then through special equipment and special techniques, through high-temperature and high-pressure synthetic diamonds, this becomes a "life source" diamond with life characteristics.
Hu Junheng, manager of the Diamond Division of the Yellow River Group, said: "In addition to hair, human nails, blood, and skin contain carbon, which can be purified and synthesized into diamonds. Such diamond-inlaid jewelry can be said to be unique and unique. significance."
Hu Junheng said that although synthetic diamonds are an industrial synthetic diamond, also known as cultivating diamonds, it simulates the principle of natural diamond growth and produces carbon in a high temperature and high pressure environment. At present, only a few developed countries such as the United States, Russia, and Japan have mastered the core technology of artificially cultivating gem-quality diamond single crystals.
At present, the Yellow River Group Diamond Division has hundreds of high-temperature and high-pressure synthetic equipment, all of which are computer controlled. One person can manage 25 machines. It is also an important diamond cultivation factory in China. Among them, it takes about one week for a synthetic block to be assembled into a diamond that is crystal clear.
The biggest distinguishing feature of diamonds from other gemstones is its "fire", that is, diamonds can reflect the colorful light and the faint light. This phenomenon is the result of the dispersion of diamonds. Among all natural gemstones, the dispersion of diamonds is the strongest.
It is worth noting that the physical properties, atomic structure and appearance of synthetic diamonds are not much different from natural diamonds, and even better than natural diamonds in terms of transparency and refraction "fire".
Hu Junheng said: "Since 2002, the Yellow River Group has started research and development of large-particle synthetic diamonds. In 2005, it successfully produced large-grain synthetic diamonds. This synthetic rough stone is no different from ordinary natural rough stones on the surface, and only the naked eye It can distinguish its color and clarity. GIA, an international jewellery authority, has issued a certificate for synthetic diamonds in 2006, which has identified synthetic diamonds as diamonds of the same quality as natural diamonds."

According to reports, the colors of synthetic diamonds are now white, yellow, blue and green. Among them, white diamonds are the most flashy, and colored diamonds are generally more than one carat.
For the price of synthetic diamonds that the public is most concerned about, Hu Junheng said: "The difference between one carat and the following is not big. The price of synthetic diamonds is equivalent to 40% of natural diamonds. The difference of more than one carat is relatively large, equivalent to 10% to 20% of natural diamonds. Therefore, it is very popular to sell more than one carat now, and now you can buy a very good carat diamond from 10,000 to 20,000 yuan, which is much cheaper than natural diamonds."
“Now we mainly produce rough diamonds, 90% of the markets are overseas, most of them are concentrated in North America, India, and Dubai, Singapore and other places. The domestic market is relatively small, but the income from the domestic market begins in the second half of 2018. The proportion has risen from 2% to 10%. At present, as a rough supplier, the polished diamonds have been embedded in various high-end luxury items such as jewellery, high-end accessories and dials, and have emerged in the jewelry market. We will expand the industrial chain and strive to form a diamond-based industrial chain with raw stone production and processing services such as grinding and inlaying to create our own diamond brand. At that time, not only the color of the diamond can be customized, shape and size. Even the materials can be customized," Hu Junheng said.
