Misunderstanding 1: Is the diamond produced in South Africa the best diamond? Most people think that diamonds made in South Africa are the best diamonds. In fact, this is the biggest lie in the diamond industry. Determining whether a diamond is good or bad is not judged by the place of origin; many countries in the world produce higher than South Africa, such as Australia, Russia, Botswana and other countries. As long as it is a diamond, no matter which country mines the same ingredients, it is elemental carbon. In addition, the diamond industry is monopolized by DTC, which has its own mines in many countries. The vast majority of diamonds have entered the market through DTC's sightholders, so even if they are jewelry wholesalers and buyers, he does not know which country the diamonds in the store really originate from. Even if it is a jewelry appraiser and a jewelry appraisal instrument, it is impossible to distinguish the origin of the diamond. To truly determine the quality of a diamond, we have to comprehensively rate the diamond, which is the comprehensive judgment of the diamond's 4C (color, clarity, cut and weight). There are also many poor diamonds in South African diamonds. Misunderstanding 2: Must buy a big brand of diamonds? Which brand of diamond is good? Diamonds are standardized products, and the identification of diamonds has strict uniform standards. The diamond itself has no brand. The quality of a diamond is not determined by the brand. The quality of the diamond is determined by the parameters of the diamond itself. The same two 30 points, H color, VS1, 3EX, no fluorescence, diamonds with GIA certificate, one is a big brand product, one is a small brand of products, the price may differ by three or four times. In fact, the prices of the two diamonds are the same in the international quotation system. Choose a big brand and bear a higher brand premium. Only diamonds that have been evaluated by the strict 4C standard know their true value, and GIA is undoubtedly the most authoritative in the world, and the value of GIA-certified diamonds is clear. Misunderstanding three: Belgian cut is the best cut? Like the first question, "The best diamonds are made in South Africa," this is also a problem that many businesses mislead consumers. The quality of a diamond cut is not based on the location of the cut. Similarly, Belgium also has poorly-cut manufacturers, and India also has high-cutting manufacturers. The quality of diamond cuts depends mainly on the cut grade of the diamond GIA certificate. Misunderstanding 4: More than one carat of diamonds will be preserved? From the perspective of the rare and expensive, the value of the diamond is indeed important. However, whether diamonds are preserved and appreciated, the channel for buying diamonds is more important. For example, diamonds purchased in shopping malls, in fact, the value of diamonds only account for about 40%-50% of the price of the label, and the rest are all occupied by the deduction point and other expenses of the mall. For example, the 10,000 diamond ring in the shopping mall, in fact, the cost is only about 4,000-5000. If you buy such a diamond, you have to wait for the value (10,000), according to the current annual increase in diamonds (about 5%-12%), you have to spend How many years can you preserve your value. With the development of e-commerce, more and more brands have begun to take the loose diamond + setting = customized mode, directly remove the cost of shopping mall operations, which is why the price of online diamond selling merchants is so cheap. Of course, the purchase of such loose diamonds, because the merchants add less profit, the price is closer to the international offer of diamonds, can be preserved and appreciated after purchase. Therefore, buying diamond channels is very important! Misunderstanding 5: Is it best to cut the eight arrows and eight hearts? the answer is negative. Eight arrows and eight hearts are just a special optical effect after the diamond is cut. I can't say that the fire of the heart and the arrow is good. The reason why the heart and the arrow are sought after by so many consumers is just the gimmick of the business. The Heart of Hearts and Arrows Diamond originated in Japan and was unintentionally discovered by Japanese in the selection of diamonds. It was added to the marketing of diamonds as a gimmick. Eight hearts and eight arrows only have a high degree of symmetry for diamond cutting and achieve a special optical effect. The average person needs to use the cutting mirror to see it, and the naked eye is absolutely invisible. If you can't see it, what is the price of the heart and the arrow? The advantages and disadvantages of the diamond cutting tool body are determined by the ratio of seven cutting ratios, namely the aspect ratio, the crown height ratio, the waist-thickness ratio, the pavilion depth ratio, the cusp ratio, the full depth ratio, and the crown angle ratio. Only when these seven ratios reach the optimal cutting ratio standard, can this diamond be truly fired, and the cutting of this diamond is a good cut. The so-called Hearts and Arrows diamonds are only within a certain range of the ratio of the aspect ratio and the pavilion depth of the seven ratios, while the other five ratios may not meet the standards. The internationally authoritative GIA (American Gemological Institute) diamond certificate does not have such a cut description of the Hearts and Arrows Diamonds. The Hearts and Arrows is definitely not the best cut, it is just a kind of good cut, it is The value of diamonds has no effect. The best cut is 3EX cut (limited to GIA certificate).
