How to tell the authenticity of silver?

Silver, I think everyone is familiar with it. In ancient China, we used silver as the currency. When it comes to silver, people will first think of silver ornaments. Silver ornaments are very common in life, including earrings, rings and necklaces. With the popularity of silver, a large number of dazzling silver ornaments appeared on the market. Although silver is worthless, it is also true and false. How to identify silver is particularly important. There are three kinds of silver identification: symbol, color and weight. Silver ornaments are usually marked with the English abbreviation of Silver. As a modern student, English abbreviations should be familiar, that is, "S" or "sterling". Standard silver seal S925, foot silver seal S990. Silver's initials will be printed on silver ornaments. As far as bracelets are concerned, when buying silver bracelets, you can see if there is a small S or the full abbreviation of silver engraved on the inside of the bracelet. If there is, then it should be true. But there are many fakes in real life, and there will be traces inside the bracelet, so this method can't be used for reference. And now many countries don't print paper money on silver ornaments, so we don't have to care so much about it. However, generally silver will have an appraisal certificate, and silver jewelry will be carried with you when you buy it. Second, look at the color. Silver is different from gold. Slightly yellow, that is, silvery white, showing a softer metallic luster as a whole. But now there are many fake and shoddy products painted with silver powder on the market, and many people will be cheated just by looking at their appearance. In addition, silver is easily oxidized. After a long time, its soft silvery white metallic luster will gradually become dark yellow white. Then there are two ways to judge, one is the combustion method. If it is true, the color of silver will not change after being baked by fire. But if it is fake silver or other inferior products, it will turn black after baking. If you really want to distinguish the authenticity of silver, you can try this method, but many people may feel distressed. Finally, the weight. The density of silver is per cubic centimeter10.53g, which is smaller than platinum and gold. If you weigh it with your hand, he doesn't think it fell. You can mark the silver with a silver needle and then bend it. If you really want to judge by your weight, you can keep a small scale at home. In addition, there are many kinds of silver now, and different silver weights are different. Therefore, if you want to buy silver jewelry, you must look at the density and proper weight of this silver, and look at it in different categories, and you can't generalize.
