I think everyone is familiar with it. In ancient China, we used silver as currency. When it comes to **, the first thing that comes to mind is silver jewelry.
Silver jewelry is common in life, including earrings, rings, necklaces, etc. With ** being sought after by the public, there is a huge amount of dazzling silver jewelry on the market. **Although it is not valuable, it can be true and fake.
How to identify ** is particularly important. **There are three types of identification: marking, color, and weight.
Silver jewelry is usually marked with the English abbreviation of silver. As a modern modern student, the English abbreviation should be familiar, which is "S" or "Sterling". Standard silver seal S925, full silver seal S990.
The English abbreviation of silver, will be hit into silver jewelry. As far as bracelets are concerned, when buying silver bracelets, you can look to see if the inside of the bracelet is engraved with the full abbreviation of small s or silver. If there is, then it should be true.
But there are many fakes in real life, and there will be marks on the inside of the bracelet, so this method cannot be used as a reference. And now many countries don't print banknotes on silver jewelry, so we don't have to worry so much about that. However, there will generally be an appraisal certificate, and silver jewelry will be carried with you when you buy it.
Second, look at the color. Silver and gold are different. Slightly yellowish, i.e. silvery-white, with a softer metallic sheen overall.
But now there are a lot of counterfeit and shoddy products with silver powder paint on the market, and many people will be deceived just by looking at their appearance. In addition, silver is susceptible to oxidation. Over time, its soft silvery-white metallic luster will gradually turn dull yellowish-white.
Then there are two ways to judge, one is the combustion method. If it's true, the color won't change after being roasted over fire. However, if it is fake silver or other inferior products, it will turn black after being roasted by fire.
If you really want to distinguish the authenticity of **, you can try this method, but many people may feel distressed. Finally, there is the weight. The density of silver is grams per cubic centimeter, which is smaller than platinum and gold.
If you weigh it with your hands, it doesn't feel like it's falling. You can use a silver needle to make a mark on the silver and bend it. If you really want to judge by weight, you can keep a small scale at home.
In addition, there are many types of silver now, and the weight of different silver is not the same, so if you want to buy silver jewelry, you must see clearly the density and weight of this silver.

Hello, the method of identifying the authenticity of silver is as follows: 1. Look at the color. The higher the fineness of the silver, the surface is a bright white metallic luster, which looks like a kind of polish and is not easy to fade, while the surface color of the fake silver is darker and has no luster, which looks dull and stiff.
2. Look at the hardness. The higher the silver content, the softer the texture and easy to deform, so in ordinary times, the pants avoid contact with hard objects, and it is easy to have obvious traces when biting with teeth, while fake silver has low fineness, high hardness, and is not easy to deform. 3. Burn with fire.
Sterling silver will generally turn white after being burned by fire, and will not turn black, if it is burned black, it means that it is not sterling silver. Burning silver with a lighter may turn the silver black, but a brush of toothpaste can turn white again. As long as it can be burned black, it is basically not sterling silver.
