Diamond 4C has nothing to do with the brand, but with the diamond certificate

The diamond 4C items are not related to the brand, but are closely related to the diamond certificate. Let's take a look at it in detail: 1. From the perspective of diamond cutting: All brand diamonds are cut in the four major diamond cutting centers, of which Belgium The Antwerp Superb Diamond Diamond 4C has nothing to do with the brand, but is closely related to the diamond certificate. Let’s take a look at it in detail: 　　　　 1. From the perspective of diamond cutting: 　　　　 All brand diamonds are cut in the four major diamond cutting centers Among them, the Antwerp Superb Diamond Processing Center in Belgium is a world-renowned diamond processing center. It has become the world’s “Diamond Capital” since the mid-15th century. 'Cutting' technology has become a universal standard worldwide.　　　　 Mumbai, India, small particle diamond processing center. The processed diamonds are mainly small diamonds, generally within 20 minutes.　　　　 Large-grain diamond processing center in New York, USA. New York, the United States, is a world-renowned large diamond cutting center, mainly processing large diamonds of more than 1 carat.　　　　 Delicate fancy diamond processing center in Tel Aviv, Israel. In the global diamond jewelry market, 40% of round diamonds and 70% of fancy diamonds are cut and processed here, with a score of 10 to 50. 2. From the perspective of the color, clarity and weight of the diamond: 　　　　 must face down when grading loose stones, while the brands are all inlaid diamonds with the table face up, so the diamond itself will have a great degree of fire The top conceals the true color of the diamond. Therefore, it is difficult to accurately determine the grade of the diamond when the diamond is facing up. Moreover, after the diamond is set, the color will be affected by the color of the surrounding metal. If the side is matched with white Metal, the color of the diamond will appear white. The 　　　　 brand product certificate cannot reliably reflect the true quality of the diamond! Because in the process of diamond processing, some flaws in the diamond and its own color can be well concealed by the inlay process! If the testing agency is not aware of it, then the grade of the diamond may be increased from color K color, clarity SI, to IJ color, clarity VS-VVS, but in this case, there will be no nakedness with international certificates. Drilling, because it is the data detected in the environment without any external influence, and can confirm the authenticity through the laser anti-counterfeiting code on the waist. Secondly, the weight of the diamond cannot be accurately measured after it is mounted. The weight of the loose diamond in the finished diamond jewelry in the mall is based on the weight engraved on the inner side of the ring arm, which cannot guarantee the actual weight of the diamond and the merchant’s Shows whether the weight is consistent. The accuracy of the bare stone is higher.　　　　 So the quality of customized diamond jewelry is more guaranteed.　　　　 3. From the perspective of appreciation: 　　　　 loose diamonds have the most processing value and have great potential for appreciation. The brand has not substantially changed the quality of diamonds, but has increased the cost of investment. Therefore, it is enough to ensure the basic quality of diamonds that can appreciate, without considering the brand of diamonds.　　　　 Fourth, from the GIA certificate: 　　　　 Some people choose the brand because they are worried about buying fake diamonds. With the GIA certificate, this problem has been solved. GIA's credibility in the certificate is No.1.　　　　 GIA is the abbreviation of GEMOLOGICAL INSTITUTE OF AMERICA, which created and proposed an international grading system. Founded in Los Angeles in 1931, the institute is trusted by the world in diamond grading and gem identification. It has a history of more than 70 years. The world’s first diamond grading system was established by GIA, and most of the world’s diamond standards, including China, are based on GIA. The diamond grading standards were formulated. As an independent non-profit organization, it is currently the most authoritative diamond appraisal organization in the world. It is no problem to look for GIA international certification. If you don’t buy GIA loose diamonds at the brand and customize the style you like, it will be more cost-effective. Use the money that is deducted on the brand's added value to buy better quality. The actual fact that larger diamonds come. 5. About loose diamond customization Process: 　　　　 according to the diamond 4C grading, according to the budget according to the '4C' order to choose and buy loose diamonds.　　　　 The first is the size, because the size is easy to see, and the greater the quality of the diamond, the more sparkling the light.　　　　 The second is color, because the whiter the color, the more beautiful and precious the diamond, and it can be distinguished by the naked eye. The third is clarity and cut. Both are invisible to the naked eye. Clarity requires a 10-20 times magnifying glass to see the number of flaws and which part of the diamond is flawed; the cut is now used The computer cuts loose diamonds, so that the loose diamonds have a better refractive surface and a more perfect fire color, and there are 57 sides of the classic cutting, so there will be no differences like the previous hand-cut loose diamonds.　　　　 Therefore, if the price is not much different, it is recommended to choose a carat diamond with a high color level.　　　　Finally choose the ring setting: you can customize the style in the picture, the six-claw classic, the four-claw show the big diamond.　　　　 The above is the information about the diamond certificate summarized by the author for you.
