Buy a cultivating diamond, would you buy it?
Natural diamonds are non-renewable resources. Diamonds have always been regarded as a symbol of love because of their rarity and natural characteristics. As the amount of mining decreased and the market demand increased, diamonds (also known as synthetic diamonds) artificially cultivated in the laboratory came into being. At the 2015 China International Jewellery Show held recently, artificially cultivated diamond products attracted consumers' attention. It is understood that, unlike the common zircon and Moissan impure diamonds on the market, artificially cultivated diamond manufacturers claim that they have the same characteristics as natural diamonds, including the same hardness, refractive index, specific gravity and dispersion rate. Guo Sheng, head of the Kelly cultivating diamond brand, which specializes in cultivating diamonds, said that there are many laboratories specializing in cultivating diamonds in the United States. The so-called artificial cultivating of diamonds refers to the use of small diamonds as “seeds†to simulate natural techniques through technical means. The diamond's growing environment allows the carbon atoms in the “nutrient†to gradually adhere to the diamond seeds, allowing the diamond seeds to grow into larger diamond crystals. At present, there are two main techniques for growing diamonds, one is high temperature and high pressure (HPHT diamond) and the other is chemical vapor deposition (CVD diamond). The diamonds cultivated by both methods have the same appearance and properties as natural diamonds. And can be issued in the GIA, IGI, HRD and other authoritative international diamond identification agencies to develop diamond grading certificates. The reporter saw that at the NGTC (National Jewelry Quality Supervision and Inspection Center) issued the jewellery jade jewelry identification certificate, the object of cultivation of the diamond was identified as a laboratory cultivation of diamonds. Guo Sheng said that in addition to the common white diamonds, pink diamonds and yellow diamonds can also be "planted" by laboratory artificial cultivation. Compared with natural diamonds, the price of cultivating white diamonds is about two-thirds of natural white diamonds. First, compared with tens of thousands of dollars or even hundreds of thousands of yuan of yellow diamonds and pink diamonds, the cultivation of yellow diamonds and pink diamonds requires only one-fifth to one-tenth of the price. However, Guo Sheng also said that compared with natural diamonds, the cultivation of diamonds does not emphasize the preservation of value, and such products are more reflected in the wearing value. Diamond products are also clearly marked during the sales process. Consumers can clearly distinguish between nurturing diamonds and natural diamonds, so cultivating diamonds does not adversely affect the natural diamond market. On the contrary, it is an effective supplement to natural diamonds. As long as the information is fully disclosed, cultivating diamonds will meet the needs of different consumers and become another choice for jewelers and designers. Key tips Natural and synthetic diamonds According to the definition of diamonds by the World Federation of Jewelry and the Federal Trade Commission, diamonds are a natural mineral that is formed entirely in nature without human intervention. The CVD synthetic diamonds are synthetic, mainly gemological characteristics, the weight is generally between 0.015ct-1.10ct, most of them are between 0.2ct-0.4ct, the color is mostly white to light yellow series, in G color-J color The color series is light red, yellow, blue, etc. Most shortwaves under UV fluorescence Below is medium to weak yellow, yellowish green, and a few are inert (no fluorescence). In an interview, Mr. Jonathan Kendall, President of the International Diamond Classification and Research Institute, told the Yangcheng Evening News: "The CVD synthetic diamonds currently on the market are about 20%-30% cheaper than natural diamonds."
