Colorful treasures are increasingly accepted and purchased by people. Then the question is coming. Do you identify the authenticity in the process of purchasing? Today, Xiaobian will tell friends how to identify the colorful treasure. The biggest characteristic of colored gemstones is that they have natural colors, red, orange, yellow, green, blue, blue, and purple. All the colors in nature can be found in the gemstones, and the beauty of the colors contained in the gemstones is any other. Material and artificial methods (such as photography and painting) are unattainable. Because of the nature of human color, after decades of colorless diamonds, colored gemstones are becoming more and more popular internationally. Moreover, because of the wide variety of colored stones and the wide price distribution, colored stones can provide a very personal choice for people of different classes and preferences. Because colored gems are color and fascinating, the color is the key to grading and evaluation techniques. According to their own research results, the gem identification and research institutions in the world have combined various localization methods and theories to summarize the color, clarity and cuts. The grading systems are similar, with no fundamental differences. Caibao optimizes the bad identification points: Due to the wide variety of color treasures, here is the choice of rubies. Used to explore the optimization process of color treasure identification. Ruby: It is a representative of red gems with extremely pure, bright colors and high hardness. Heat treatment and crack filling treatments are common. After the introduction of the simple heat treatment color change method, it has been accepted by the industry and the market. However, with the release of the ruby ​​after the rapid ruby, how to disclose the heat treatment and crack filling treatment has been controversial. Some laboratories in Thailand believe that colorless fillings should only be visible at 10x magnification before they are declared on the certificate of appraisal. After more than two years of research, Gubelin Labs proposed a method for comparing heat treatment cracks with standard stone. And the classification of the amount of filling residue (ie, NTE is not treated by heat treatment, and the number of heat treatment residues is expressed as TE1-TE6 in as little as possible. This classification method has been accepted and adopted by many laboratories). Recently, there have been large magpies filled with lead glass. The appearance of such gemstones is quite confusing, but there is a "flash" effect under the microscope. The evaluation of colored gemstones for the evaluation of colored gemstones is based on identification and grading. The identification of colored gemstones is a professional focus of the evaluation of colored gemstones. The optimized processing technology and identification methods of colored gemstones are always alternately developed, which in turn affects the supply and demand of the market, resulting in fluctuations in the value of colored gemstones. It can be seen that the evaluation of colored gemstones must be sensitive to market changes and benefit from the latest identification research results. Only based on reliable identification conclusions and market analysis methods can a reasonable evaluation conclusion be derived. Caibao origin identification: Colored gemstones pay attention to the origin, the origin itself is a brand. Rubies of the same weight and grade, produced in Myanmar, are much higher than those produced in Thailand. Overall, the best place to produce rubies is in Myanmar, emeralds are in Colombia, sapphires are in Myanmar, Sri Lanka and India, and cat eyes are in Sri Lanka. No matter which colored gemstone you choose, quality is the key. The difference in quality fundamentally determines the price of colored gemstones. He recommends that consumers identify with "4C2P", namely color, clarity, carats, cut, pedigree, and purity. The color is the most important in the 4C of colored gemstones, which is an element that consumers need to pay special attention to. For example, the blue of a good sapphire should be blue and clear, not gray or dark. Ruby is best to buy pigeons with red blood quality. If you want to increase the value, the weight is at least 2 carats. Have you remembered the above identification points?
