Louis
The silver jewelry can be divided into sterling silver, pattern silver and color silver from high to low. According to the processing method, it can be divided into cast silver, creating silver and silver fine work products. The identification of silver jewelry can also adopt methods such as seeing color, test hardness and elasticity, weight, listening rhyme, reagent test and other methods. The silver jewelry has a color of more than 97 %, the epidermis is white and delicate, and the luster is soft and pleasant. The lower color of the skin is blue or gray, and sometimes it is yellow and black. The silver jewelry itself is very plastic, and the shape is changing. It is no longer a simple sterling silver jewelry in our impression. It has a lot of fashion elements in styling, variety, and craftsmanship, and the sales of silver jewelry are also increasing year by year. In addition to sterling silver jewelry, there are black silver jewelry, Tibetan silver jewelry and color silver jewelry. The temptation of silver jewelry is that it can inlaid gems or imitation gems and other materials, which is more diverse. Although the raw materials of the silver are very cheap, there will be some manufacturers who are cheaper metal such as cadmium, iron, and copper in silver jewelry. Cadmium is harmful to the human body, and it is not allowed to be mixed in jewelry according to regulations. Manufacturers do this mainly to reduce costs and get higher profits. The copper wire is mainly mixed with the middle support frame in the silver lock. The supporting frame in the silver lock according to the national regulations should also be silver. Because the copper silk is hidden in the silver lock, consumers can't see it at all. Only when the jewelry detection is performed, it can see the true face of Lushan. Only when it is waiting for a long time, the copper rust inside is exuded can consumers find it. Although silver jewelry is not valuable, it is true and false. Although this phenomenon is not common, consumers should still master some methods of identifying silver jewelry. Consumers can be tested through the physical properties of the silver when purchasing. The usually test methods are: look at the color of jewelry: the higher the purity, the white the silver, the surface of the jewelry, the surface of the jewelry looks uniform and bright, and the color is moisturized. If it contains lead, the jewelry will show blue and gray; such as copper, the surface of the jewelry will appear rough, and the color is not moisturized.银 Jewelry Weight: Silver density is slightly larger than common metals. Generally speaking: "Aluminum is light, silver, and copper is not light and not heavy." Therefore, the weight can make a preliminary judgment on whether it is silver. If the jewelry is large and the weight is lighter, it can be preliminarily determined that the jewelry is other metals. Check hardness: Silver hardness is lower than copper, and is large than lead and tin. It can be tested with inconspicuous places with large head needles. If the needle is slippery, it is difficult to leave traces on the surface. The tin texture, the traces are obvious and prominent; if there are traces of the facts, but not obvious, it can be initially determined as silver jewelry jewelry. Listening rhyme: Silver jewelry jewelry throws sound, no elasticity, and the sound is "卟 卟 卟 听". The lower the color, the lower the sound, and the higher the sound, the higher the rhyme; if it is copper, the sound is higher and sharp, and the rhyme sounds are short and short; , No elasticity. It is not an ideal way to test silver jewelry by the physical properties and experience of silver alone. Only by destroying silver jewelry can use chemical methods can the true and false and disadvantages of the true and false of silver jewelry. However, this is not reached by consumers. In addition to mastering some basic inspection knowledge when buying silver jewelry, consumers should also pay attention to whether the silver jewelry has relevant certificates, certificates, and certificates. Only the silver jewelry detected by the testing agency can buy it. In addition, the silver content of silver jewelry must be accurately indicated that consumers should check whether there are "925" on the jewelry when purchasing. "925" is a symbol of sterling silver. As long as there is "925", you can ensure that what you buy is a real sterling silver jewelry. When buying, pay special attention to whether its deduction can be deducted and reliable. When buying the silver chain jewelry, you should flatten it to see if the chain ring is knotted or bent. The price of silver jewelry is determined by the content of precious metals, structural design and craftsmanship, so the most important criterion for choosing silver jewelry is to depend on whether you like it. The identification of 925 silver jewelry. The knowledge of sterling silver XIAO is an indispensable combination metal in K gold jewelry in 925 silver silver. The hardness of the silver is 2.7. In order to improve its hardness and obtain the best molding effect, it is necessary to add 7.5 % copper to the silver when making jewelry. This silver containing 92.5 % and copper -containing 7.5 % alloys, which are called standard silver internationally. It is also known as the British Sterling. In addition, there are foot silver jewelry with a silver content of 99 % in the market. 925 Silver is the international standard silver of the international silver jewelry. It is different from 9.999 silver, because the purity of 9.999 silver is relatively high, it is very soft and difficult to make complex and diverse accessories, and 925 silver can do it. The 925 silver jewelry is not 100%of the silver content, because the 7.5%alloy added to the sterling silver improves the luster, brightness and hardness of the silver. Only we have the colorful silver jewelry today* _* the identification of the silver 1) mark. Silver jewelry should generally be marked with Yin's English abbreviation ("S" or "Sterling"). The mark of the standard silver is S925. Foot silver's mark is S990. However, many countries do not print on silver jewelry. 2) Color. The silver jewelry is mostly yellowish white, with a soft metallic luster. Because it is easy to oxidize, the color will become dark yellow and white. 3) Heavy. The density of silver is 10.53 grams / cubic centimeter. Smaller than platinum and gold, without falling feel. Steel needles can draw traces or bend. In this way, it can be different from the platinum owner, K platinum or imitation silver. 4) acid test. Silver will change color and even dissolve. If a drop of concentric acid is dripped on the inner side of the silver jewelry, a white moss -like silver chloride sediment will be generated immediately. Other precious metals have no such phenomenon. 5) Sound rhyme. After the standard silver jewelry landed, the sound was dull, no bounce, no rolling.
1. Look at the mark: The silver content in accordance with the national regulations must be accurately indicated. When purchasing consumers, consumers should check whether the jewelry is about whether the jewelry is related to the purity. AG990 (traditional bracelet child lock). If there is no sign, it can basically be concluded as ordinary metal.
2. Seeing color: The silver jewelry is mostly yellowish white with yellowish white, with moisturizing.
3, look at the price: The price of silver on the Shanghai Gold Exchange is about 5 yuan per gram. It must be insufficient purity or fakes.
4, 掂 weight: The silver density is slightly larger than the general common metal, 10.53 grams / cubic centimeter, so the weight can make a preliminary judgment on whether it is silver.
5, check hardness: The silver hardness is low, and the silver jewelry is lightly folded by hand. Or use the large head needles to be inconspicuous. If the needle is slippery, it is difficult to leave traces on the surface, and it can be judged as copper jewelry; if there is traces of the physical object, but not very obvious, it can be judged as silver jewelry. This method has been widely used for people since the ages. People who see the wealth of wealth in the costume movies often receive Yinyuan and bite with their teeth. In fact, they are detecting hardness.
6, acid reality: The silver will change color and even dissolve. If a drop of concentric acid is dripped on the inner side of the silver jewelry, a white moss -like silver chloride sediment will be generated immediately. Other precious metals have no such phenomenon.
7, listening to sound rhyme: The standard silver head jewelry is dull and non -elastic after landing. If it is copper, its sound is higher and pointed, and the rhyme is short and short; The method of comprehensively using the authenticity of silver decoration is absolutely no problem. If the sky can be seamless, then his cost is better than the real one. The sterling silver is much higher, so there is no profit. If consumers want to know the very accurate content of the silver jewelry they purchased, then they can only go to jewelry or precious metal testing center for testing. Also pay special attention to whether its fastening can be deducted and reliable. When buying the silver chain, you should flatten it to see if the chain ring is knotted or bent. Ifine jewelry is generally divided into electroplating and non -plating without plating: The electroplating: that is, the inner layer is sterling silver, and the surface is plated, mostly plating in platinum; It is lighter than sterling silver, the reflective effect is very good, it is not easy to oxidize, and fashion products are mostly used in this process. The plating without electroplating: Although the natural and simple luster of sterling silver is retained, it is easy to be dark or yellow due to vulcanization. The reason is as dark as the apple after cut). You need to use silver cloth for maintenance to restore its gloss.
The color is gray -black color, small hardness, small hardness, can bite the tooth print with teeth, strip signs of silver white, metallic luster, silver and white stripes.
