Synthetic Diamonds vs Natural Diamonds 2016 Quietly Starts

In 2016, natural diamonds and synthetic diamonds are like two dazzling "gemini stars", both of which step into the center of the stage of the jewelry circle.
At the Basel show in March this year, Russian synthetic diamond producer New Diamond Technology (NDT) presented a 5.03 carat, VS1 clarity, emerald cut IIb high temperature and high pressure (HPHT) synthetic blue diamond, which was diamond The community is widely concerned.
On April 5th, in the Hong Kong Sotheby's Spring Auction, a 10.1 carat, IF clarity, the largest oval blue diamond in the history of the auction, sold for 248.28 million Hong Kong dollars (about 31.8 million US dollars), also in jewelry The circle caused a huge response.
You sing, I will debut. Natural diamonds and synthetic diamonds have provoked waves of public opinion, which means that the natural and synthetic diamonds have quietly started in 2016.
How to look at the impact of the emergence of synthetic diamonds on the natural diamond market, whether the marketing strategy of the natural diamond market will change due to the development of synthetic diamond technology, how to build a healthy diamond ecosystem - is placed in every diamond industry The problem before the person.
On April 22nd, a seminar hosted by Guangzhou Diamond Exchange Center and UBM Asia was held at the Shenzhen International Jewelry and Jade Exhibition on the theme of “Natural and Synthetic·Perspective Global Diamond Industry Status”. At the seminar, the fog that shrouded the synthetic diamonds was gradually removed.

"spoiler"
In 2012, the National Jewelry Quality Supervision and Inspection Center (Shenzhen) Laboratory was the first to discover a batch of undisclosed synthetic diamonds during the testing process. Since the first half of 2015, NGTC laboratories have also found small diamond HPHT synthetic diamonds in natural diamonds with matching or group inlaid gemstone samples.
Synthetic diamonds are currently cultivated in two ways: high temperature and high pressure (HPHT) and chemical vapor deposition (CVD), but no matter which method is used, the composition and properties are not different from natural diamonds.
According to Lu Taijin, chief researcher of the Jewelry and Jade Jewelry Management Center of the Ministry of Land and Resources, the technology for cultivating diamonds in the laboratory originated in the 1950s and has achieved a qualitative leap in the past 10 years. Synthetic diamonds are mainly used in aviation and military industry. Gem-quality synthetic diamonds have only appeared in recent years and have reached a marketable level in terms of quality and cost.
With the continuous development of diamond synthesis technology, the advantages of synthetic diamonds compared to natural diamonds have become more apparent. It is understood that in the five years from 1985 to 1990, the growth rate of Ib-type synthetic diamond single crystals increased by 275%, more than four times that of the past 15 years; from 2005 to 2015, the growth of synthetic diamonds The cycle has been shortened by 5 times and the price has dropped by 50% to 70%. At the same time, the technology of making synthetic diamonds using carbon dioxide and magnesium carbonate has made breakthroughs in the academic world. "Hair diamonds" or "ash diamonds" have become a reality, and the range of synthetic diamond production materials will be further expanded.
Compared with synthetic diamonds, the natural diamond market is currently facing no small challenge. Lin Weixiong, vice president of marketing consultancy for De Beers Group Greater China, said that although China’s diamond demand has declined in the past two years due to China’s macroeconomic impact, he expects natural rough diamond output to appear annually from 2019. 1% to 2% decline, while diamond sales will increase by 3% to 4% per year, and the gap between supply and demand will further expand.
"On the one hand, there are fewer and fewer diamond mines, the mines are deeper and deeper, and the cost of diamond mining is rising. On the other hand, as the US economy recovers and the rise of the middle class in China, India, Brazil and other countries, the demand for diamonds will There is an increase or decrease. These factors will promote the rise of natural diamond prices." Lin Weixiong said.
In addition to the impact on natural diamonds in the price system, the concealment of synthetic diamonds also adds to the risk of the diamond market. According to Liu Houxiang, deputy director of the National Jewelry Quality Supervision and Inspection Center (Shanghai), the total weight of natural diamonds in the world is about 115.13 million carats, and by the end of 2015, the total weight of synthetic diamonds in the world exceeds 7 billion carats, which is natural diamonds. 69 times. At present, China has become an important synthetic diamond production base, mainly concentrated in Henan and Shandong provinces. Most of them produce HPHT (high temperature and high pressure) synthetic diamonds, which can produce single-particle colorless gem-quality synthetic diamonds up to 16% per month. Ten thousand carats to 200,000 carats.
According to Liu Houxiang, since the distribution channels of synthetic diamonds and natural diamonds are basically the same, 70% to 80% will be processed and cut in India and then distributed to all parts of the world. However, in the specific operation, some large diamond cutting companies in India have entrusted some small diamonds to the third-party small workshops in order to control the cost, which makes the final destination difficult to track. "This problem of unreliable supply from the source has led to the possibility of synthetic diamonds mixing in various subsequent stages, such as diamond import and export transactions, wholesale, mosaic processing, retail and other links."

Positive response
In the face of the impact of synthetic diamonds, the diamond industry, including industry associations, quality inspection agencies, trading centers, manufacturers, retailers, etc., although the attitudes are not the same, but they have shown a positive side.
In November 2013, the World Diamond Center Alliance (WFDB) issued an official warning: Any confession of intentional and deliberate misrepresentation of synthetic diamonds, the WFDB will take serious action. Some world-renowned identification agencies such as GIA, IGI, and HRD have begun to provide grading services for synthetic diamonds and actively maintain market order.
“Protecting consumer rights is the obligation and responsibility of each industry.” Liang Weizhang, general manager of Guangzhou Diamond Trading Center, believes that because the difference between synthetic diamonds and natural diamonds cannot be discerned by the naked eye and simple equipment, it must rely on the strength of professional jewelry appraisal institutions. . “Because of this feature, we need to ensure that the channel and consumers have full right to know during the sales process, and we need to fully assist in maintaining the existing industry order and support the healthy development of the entire diamond industry.”
As a representative of the diamond industry leader De Beers, Lin Weixiong fully believes in the self-regulation ability of the diamond industry. He believes that consumers should be respected for their autonomy in buying diamonds. At the same time, he said that De Beers will use the unique "seekers" system to increase cooperation with existing distributors, while providing more professional troubleshooting equipment to the market, as well as providing De Beers's exclusive certificate," Multi-faceted to enhance consumer confidence."
A good monitoring mechanism is a necessary condition for maintaining the healthy development of the diamond ecological environment. The National Jewelry Quality Supervision and Inspection Center (NGTC) has been closely monitoring the market development of high temperature and high pressure synthetic diamonds. Liu Houxiang said that NGTC will respond to the impact of synthetic diamonds in accordance with the "4D" process, that is, to find differences, effective testing, clear identification and certificate certification. At the same time, he hopes that the diamond industry will form a complete "protection chain" from all aspects of supply, production, retail, inspection, etc., and suggest that relevant enterprises take the initiative to conduct product property inspection during the loose drilling stage.
For the prospect of the future diamond market, Qiu Zhili, a professor at the School of Earth Sciences and Geological Engineering of Sun Yat-sen University and director of the Research and Appraisal (Assessment) Center of Sun Yat-Sen University, believes that the future market will change from the current “natural diamonds dominate the world” to “very clear natural The situation of diamonds, ambiguous diamonds and true synthetic diamonds in the world. He believes that the emergence of synthetic diamonds has brought about the reconstruction of the value of diamonds. Natural diamonds and synthetic diamonds are beautiful incarnations, but their functions are different: the former is the essence of nature, high quality and rare, and has certain investment attributes; the latter is the crystallization of human wisdom, is an excellent high-tech material, the main decorative function . “Natural and synthetic diamonds will form an interdependent pattern. The industry will compete and interact, and the boundaries will become clearer and eventually achieve a dynamic balance at some stage.”
