With the changes of modern women's aesthetic psychology of jade, the inlaid jade of fashion personality has gradually become a hot spot of jewellery and jade consumption and a new favorite of the jade market. The classical and beautiful jadeite jade is perfectly combined with the modern and fashionable gold ornaments. The metallic luster and the emerald color complement each other, injecting a fresh vitality into the jade itself, and bringing the green of the jade to the brightest. Moreover, more and more famous movie stars are wearing intensive emerald rings and pendants to participate in the international awards evening, which will bring the stars' vitality, dynamic, elegant and feminine to the air. This further spurred the enthusiasm of people to buy inlaid jade. However, in the process of purchasing, people found that the mosaic jade has a back cover, and some have no back cover. (The so-called back cover, that is, the bottom of the jade jewelry is covered by the decoration, the jade is wrapped inside, can only see whether the outer layer is glamorous, neither know whether there are cracks on the bottom, or how thick it is.) What is better? Classification of jade back cover The back cover is divided into three categories: “coveringâ€, “sealing†and “net sealingâ€. After the cover is closed, it can also be opened to view the bottom of the jade to facilitate the identification of jadeite; and "sealing" and "net seal" are usually not open without the help of professional tools. The advantages of jade back cover The first is safety, which can protect the jade from damage; Secondly, it is landscaping, which allows the emerald color of the glass to be concentrated and looks more beautiful. For example, a piece of bright green and green jade is very beautiful. The fly in the ointment is cotton. The cotton on the skin is more conspicuous, but it can be used to visually fade the cotton and make it emerald. More colorful, more beautiful, more perfect; The third is to keep the bottom clean and not easy to hide dirt. What jadeite is useful for the jade? 1. The jadeite with rich color will generally be sealed. Because the color is too thick, it will consume light and lower the head. Generally, there is a head that advises the customer to seal the bottom. There are several types: a, light color. Generally, the yellow bottom is sealed, and it is less suspended, so it is very good. If the color is light and uneven, seal the yellow bottom and do not hang. b, the color is slightly darker. The white background is slightly suspended. c, the color is deep and uneven. Seal the white background, not hanging. d, there is a light color. The bottom must be sealed so that it retains the color and increases the head. e, color is not full. It is also necessary to cover the bottom so that it can be concentrated. 2, the color of the thick plane jade must be sealed. Due to the rich color and the lack of light to scatter the color, the only way is to rely on the reflected light from the back cover to disperse the color. It has no effect on the jade back cover with poor water quality. Light can't penetrate the jade, even if it enhances the reflected light, it will not help. Disadvantages of jade back cover The drawback is that it is also possible for the merchant to cover the bottom of the bottom to cover the bottom, and it is not easy to see the thickness after the back cover. In this way, the merchant may be able to sell at a high price. Here, jade experts remind the vast number of jade lovers, if you buy with jewelry, the problem of the back cover is not big; if you are holding a collection of mindset to buy inlaid jade jewelry, it is recommended to buy "live bag", after all, "live bag" inlay Jade jewelry has higher quality and more room for appreciation. Precious metals commonly used in jade inlays: 1, silver Silver has a history of more than 4,000 years. Because it is silvery white, the gloss is soft and bright, the chemical properties are stable, the activity is low, the heat conduction and the electrical conductivity are relatively good, it is not easy to be corroded by chemicals, the quality is soft, and it has good ductility. The price of silver is relatively low, and the cost is low in the use of inlays, and most of them are used to inlay low-grade jade. 2, K gold K gold refers to the alloy of gold and other metals. K gold has the characteristics of high hardness, high toughness, not easy to be deformed and worn, colorful and durable, and relatively inexpensive. In addition, according to the amount of gold, K gold is divided into 22K gold, 18K gold, 9K gold, etc., but in fact, the jade mosaic is mostly K gold 18K. 3, platinum Platinum is a naturally occurring white precious metal that was used as early as 700 BC and has been used for more than 2,000 years. Pure platinum is silvery white, beautiful in color, metallic luster, strong ductility, refractory, anti-friction, anti-corrosion, chemically stable and anti-oxidation. However, the production of platinum is extremely rare and can only be mined in a few places in the world and is considered to be one of the most expensive metals. Inlaid with emerald in platinum, its natural white luster can be a good way to bring out the beauty of jade, but also more secure and safe. 4, pure gold Pure gold, in theory, refers to gold with 100% gold, also refers to 24K gold. However, in reality, it is impossible to have gold with 100% gold, so China stipulates that as long as the gold content reaches 99.6% (including 99.6%), gold can be called pure gold. Pure gold has a soft texture that highlights the delicate craftsmanship and detail of the design. The pure gold color is thicker and yellower, and it is not easy to be oxidized. If the proper color is maintained, it will remain bright for a long time. In addition to the precious metals listed above, precious metals such as gold, gold and gold are often used to embellish jade jewelry. However, many jadeites with cheap metal inlays may have some quality problems or B goods, so when you purchase jade jewelry, you need to identify the certificate of the formal inspection agency!
