Diamonds can be said to be the love of many women, but also the "heart treasure" of many collectors, but friends who love diamonds, buy diamonds, remember not to blindly pursue the level! Colored diamonds are the essence of diamonds and are rare. It is said that every time 100,000 gem-quality diamonds are produced in the world, it is possible to encounter a colored diamond. The formation of colored diamonds is due to the different chemical trace elements and internal crystal structure deformation during the formation process. In general, the rarer the color, the higher the color level and the higher the value; the thicker the color, the higher the saturation and the higher the value. The value of the colored diamonds is higher in the red series, followed by the blue and green series, while the value of the black diamond is lower. The price of colored diamonds is more than two hundred times higher than the same volume of colorless diamonds, more than two thousand times more expensive than the same weight of gold, and is considered to be "concentrated wealth." A 0.95-carat red diamond auctioned at Christie's in Hong Kong in 1987 was sold for $880,000. Because of the diversity of color diamonds, the pricing of colored diamonds is difficult to unify. So far, there are still no international quotations for color diamonds to follow. The colored diamonds with investment value can now only appear in the auction, and the auction price has been continuously refreshed in the past decade. In October 2007, a blue diamond ring auctioned by Sotheby's auction house weighed 6.04 carats and the transaction price reached HK$61,927,500. At the Christie's auction in London at the end of 2008, the European royal family named "Blue Wits Bus" was sold at a high price of 16.4 million pounds, setting a record for the price of diamond auctions. The rare charm of colored diamonds dumps many celebrities. Liang Chaowei once gave Liu Jialing a 12-carat Cartier American pear-shaped diamond ring worth 100 million Taiwan dollars, but this record was recently refreshed by Hong Kong rich businessman Liu Yuxiong. He bought 7.03 carats of blue diamonds for more than NT$314 million, and gave Liu Xiuhua the love of his girlfriend Ganbi. Diamond price: two days at home and abroad Ancient Chinese studied jewels and jade, but they paid little attention to the diamonds of the King of Gems. However, as the degree of openness accelerates, people are increasingly accepting and loving this jewel. Under the global financial tsunami, our residents have not significantly reduced their consumption of diamonds. To some extent, this is a proof. Residents in the eastern coastal areas of China have long formed the concept of buying diamond ornaments, and the demand is gradually stabilizing. The economy is in the mid-west of the take-off, and people gradually accept the gemstones, thus showing a trend of increasing demand. Although the domestic and international markets are hot and cold, the price of diamonds is still strong, because the number of diamond deposits in the world is scarce and diamonds are scarce like gold. More than one carat has a collection value Not all diamonds have a value-preserving and investment function. For the most common white diamonds, the 4C standard is the basic measure of the value of diamonds, namely weight, color, cut, and clarity, and the primary factor in determining the value of a diamond is weight. In the diamond industry, less than 75 points for small diamonds, 75 points to 2 carats for medium diamonds, 2 carats to 10.8 carats for large diamonds, and 10.8 carats or more for extra large diamonds, while diamonds weighing more than 1 carat are collectible. . The reason is very simple. In European and American banks, diamonds can be mortgaged, but only for diamonds with a large certificate of more than 1 carat, and diamonds with less than 1 carat have only a small certificate, and the bank does not recognize the account. This has created the concept of “carat premiumâ€, in which the price of diamonds at a weight of 1 carat will change dramatically, and the price difference between 0.99 carats and 1 carat diamonds can be very different. In addition to weight, it is also necessary to consider the color, clarity and cut of the diamond. In general, the color should be above the G level (nearly colorless), the clarity level is above VVS (only difficult to see under ten times of magnifying glass), and the cut grade is above 'good', which has a collectible value.
