Colored gems, also known as colored gems, are the collective name for all gems of natural gems except diamonds. Among them, rubies, sapphires, emeralds, gold emeralds, etc. are the most precious, and the diamonds are listed as the world's five rare precious stones. With the gradual popularization of "color treasures" in recent years, emeralds are becoming more and more popular among the public. The insiders reminded the public that natural gemstones are "twelve treasures" and that natural gemstones without any cracks and cracks are extremely rare. But if it's about clarity, emeralds are even more "cracked" than gems, and buying emeralds must not be exacting. How did the name of the emerald come from? Is it only a grandmother or an older person who can wear it? According to industry insiders, emerald is an imported product from the West. It was originally transliterated in ancient Persian. It has been circulated since the translation of "West Chamber" into "Emerald". In fact, this green and pleasing gem is also very suitable for young people to wear. As a colored gem, color is the most important evaluation criterion. The greener, more pure, natural, and more expensive emerald color; the second is transparency, the more transparent the better. Some emeralds have been polished into a curved shape, precisely because of its poor transparency, more inclusions, and can cover up some defects after polishing; the third is to look at the clarity, the more expensive the emerald is more expensive. The clarity of emeralds is difficult to meet the standards of diamonds; the fourth is to look at the size, the bigger the emerald price is, the more expensive; the fifth is to look at the cut, the better the cut, the more expensive the price. In recent years, the price of emeralds has been rising, and individual merchants have treated the embarrassing emeralds to enhance their value. According to industry insiders, there are currently three ways to optimize the treatment: oil immersion, filling and laminating. By immersion oil, it can cover the emerald cracks, making the emerald more bright and thorough. The immersion colorless oil is optimized, which is allowed by national standards. If it is immersed in color oil, such as green oil, it will deepen the color of emerald. The certificate of gem identification must be marked with “dipped oilâ€. However, the immersion oil is not as good as the filling, and it is stable. If the filling is large, the filled gemstones must also be marked on the certificate to indicate the consumer. The film is a relatively low-level treatment. It is covered with a layer of colored film on some of the lighter emerald surfaces. It is equivalent to fraud, and it must be noted on the certificate. People who love emeralds must first look at the price when they buy, but when they buy emeralds from regular businesses, they rarely have 5,000 yuan or less. The second is to look at the smoothness and color. The color of true emerald is only yellow green and blue green. The brilliance is soft and bright, showing a velvet lawn-like color level. The third available desk lamp or hot needle is close to the product to be heated. If oil leaks out of the crack, or if it is wiped with cotton paper or lens paper, it is proved to be optimized. In addition, the best cut method for emeralds is square cut. The industry reminds the public that it is best not to go directly to the website to buy, although the online price is 10% lower than the market price, but the online security is poor, the quality can not be guaranteed, and the risk is far more than 10%.
