Silver jewelry can be divided into pure silver, silver and silver according to its color. According to the processing method, it can be divided into casting silver and silver and silver fine products. The identification of silver jewelry can also be used, such as color, hardness and elasticity, weight, sound, reagents and other methods. The quality of silver jewelry is over 97%, the skin is white and delicate, and the gloss is soft and pleasing to the eye; the lower color of the skin is white or gray, sometimes yellow, black and other variegated colors, and the color is dim and dull.
Silver jewellery itself is very malleable and has a variety of shapes. It is no longer the pure sterling silver jewelry we have in mind. It has a lot of fashionable elements in terms of styling, variety and crafts, and the sales of silver jewellery are also rising year by year. In addition to sterling silver jewelry, there are also black and silver jewelry, Tibetan silver jewelry and silver jewelry. The tempting aspect of silver jewellery is that it can be inlaid with materials such as gems or imitation gems to make it more diverse. Although the raw materials of silver are very cheap, there are some manufacturers that incorporate cheaper metals such as cadmium, iron and copper into their silverware. Cadmium is harmful to the human body and is not allowed to be incorporated into jewelry according to regulations. Manufacturers do this mainly to reduce costs and achieve higher profits. The copper wire is mainly used in the silver lock to make the middle support frame. According to the state regulations, the support frame in the silver lock should also be silver. Since the copper wire is hidden inside the silver lock, the consumer can't see it at all. Only when the jewelry is inspected, it can be destroyed to see its true face. Only after waiting for a long time, the inside of the copper rust seeps out, consumers can find out. Although silver jewelry is not expensive, it is also true and false. Although this phenomenon is not universal, consumers should still have some methods to identify silver jewelry.
When consumers buy, they can be tested by the physical properties of silver. The usual test methods are: look at the color of the jewelry: the higher the purity, the whiter the silver, the uniform and shiny surface of the jewelry, and the touch. If it contains lead, the jewelry will appear blue-gray; if it contains copper, the surface of the jewelry will appear rough and the color will not be moisturized. Check the hardness: the hardness of silver is lower than that of copper, and it is more than lead and tin. It can be tested in places where the pins are not smudged. If the needle is slippery and the surface is difficult to leave traces, it can be judged as copper jewelry; The tin texture, the traces are obvious and prominent; if the real objects have traces and are not obvious, they can be initially judged as silver jewelry. Listening to the rhyme: The sterling silver jewelry has a sound, no elasticity, and the sound is "åŸå“’åŸå“’". The lower the color, the lower the sound, and the higher the sound, the more rhythm; if it is copper, the sound is higher and sharper, the rhythm is short and short; if it is lead or tin, the sound is dull and short. , no stretch.掂 Jewelry weight: The density of silver is slightly larger than that of common metals. Generally speaking, “aluminum is light, silver is heavy, 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 in size and light in weight, it can be preliminarily judged that the jewelry belongs to other metals. It is not an ideal method to test silver jewelry solely by the physical properties and experience of silver. Only by destroying the silverware can the chemical method be used to test the true and false of the silverware. However, this is something that consumers cannot achieve.
In addition to mastering some basic inspection knowledge, consumers should also pay attention to whether silver jewelry has relevant certificates, certificates and certificates. Only silver jewelry that has been tested by the testing agency can be bought with confidence. In addition, the silver content of silver jewellery must be accurately marked, and consumers should check whether there is "925" on the jewellery when purchasing. "925" is the symbol of sterling silver. As long as there is "925", you can ensure that you are buying genuine sterling silver jewelry. Pay special attention to whether the fasteners can be fastened and secure when purchased. When buying silver chain jewelry, flatten it to see if the chain is knotted or bent. The price of silver jewellery is determined by the content of precious metals, structural design and craftsmanship, so the most important criterion for choosing silver jewellery is to see if you like it!
