Uncover the mystery of the expensive and precious gem "emerald"
Uncover the mystery of the expensive and precious gem "emerald" The scarcity of production makes emeralds not appear frequently in the jewelry market, which makes it seem like a veiled green mystery. People always feel the fog in the fog. Let us help you to uncover this veil today. Show the emerald side that you must know. 1. The best emerald resort - Colombia The distribution of emeralds is not unique and is found in many countries. The earliest discovered and mined emerald mine in the world is the Cleopatra deposit in Egypt. But the real large-scale mining was in 1537 in Colombia, South America, with the highest output and the best quality, accounting for 80% of the world's total production, about 2 million carats of emerald raw materials. In addition, Zambia in Africa, Zimbabwe; Australia in Australia; Brazil and other countries and regions in South America have produced, but the quality can not be compared with Colombian emerald. 2, the most critical price factor - production is scarce Although emeralds are produced in many parts of the world, the quality of emeralds is still far below the production of diamonds of the same quality. Almost one out of every 1 million beryl minerals is emerald. Emeralds are brittle and easy to crack during the mining process. The emeralds, which are rare and difficult to produce, are rare and precious stones. They are the top jewels of the sorghum imported color gemstones. 3, the most important criterion - color The green color of emerald determines its value. Too light or too deep is not a good product. Medium green and beautiful luster are called the best. The chromaticity is thick and vivid, and the tone is medium to medium. Good transparency and even color distribution. Even a slight chromatic aberration will have a huge impact on prices. It is generally believed that the emeralds produced in Colombia's most famous Chivor mine and the Chivor mine will be slightly blue, which is considered to be the best quality emerald, if at the same time Good characteristics, etc., then it is the best. 4, the most demanding elements - 100% pure Although the more clear and precious, the emeralds are mostly transparent, but the impurities are therefore more easily seen by people, which is a basic basis for confirming the "natural" gem. Natural colored gemstones will not be 100% pure. Impurities and cracks are the characteristics of all natural gemstones. There are sayings of “Ten Treasures and Nine Cracksâ€. Colored gemstones mainly rely on their own color to win. The purity requirements cannot be compared with diamonds. The judging criteria are equated. 5, the best cutting method - emerald cutting The most common of the main cutting methods of emeralds is “emerald cuttingâ€. Emerald cutting used to be mainly used in emeralds to reduce the enormous pressure created during cutting, thus protecting the gemstone from cuttings. This problem is now less important in modern cutting technology, which is widely used in many types of gemstones. The number of facets of the "emerald cut" cut gemstone is about 50. The emerald cut is viewed from the top like a rectangle with a truncated corner. With a stepped facet, it can be a very beautiful gem; the brilliant brilliance will show the brilliance of these stepped corners on the gemstone pavilion. This is another "trapezoidal cut" that has multiple layers of steps that are similar to steps and are usually four corners or elongated. It is called trapezoidal cutting because it is a concentric and wide plane with a step. 6, the most basic investment standard - more than 1 carat When you talk about precious stones, the name of "diamond" will be blurted out. In fact, an emerald of the same quality as a diamond is much higher than a diamond. Emeralds are mostly small particles, generally less than 1 carat. If the emerald is of good quality and can reach more than 1 carat or even more than 2 carats, it is already very precious and the price will be astonishingly high. 7, the biggest purchase trap - artificial breeding If you want to buy some emeralds when you travel abroad, be careful. Because there is a kind of "cultivating emerald gemstone", its manufacturing process is ground and purified by chlorite with poor natural quality, and then cultivated by high temperature and high pressure. Its characteristics are bright and dazzling, crystal clear and very attractive. These artificial gemstones sometimes appear in the jewelry store designated by the travel agency. Don't see the beautiful gemstones plus the ultra-low discounts of the merchants, thinking that they have won the grand prize. Because the quality of pure natural emerald is expensive and will never be discounted, although the artificially cultivated emerald is also made of natural beryl, the price will vary greatly.
