Identification method:
1, look at the brand:
According to national regulations, the silver content of silver jewelry must be accurately marked. When consumers buy jewelry, they should check whether there are purity marks S925 and Ag925 (fashionable ones are more common), or S990 and Ag990 (traditional bracelet child lock). If it is not marked, it can basically be concluded that it is ordinary metal.
2, look at the color:
Silver ornaments are mostly yellowish silvery white, which has a touch-up.
3. Look at the price:
At present, the price of silver in Shanghai Gold Exchange is around one gram of 5 yuan, without adding purchase cost and processing cost. If the price is ridiculously low, it must be impure or fake.
4. Weighing:
The density of silver is slightly higher than that of ordinary metal, which is 10.53g/cm3. It can be preliminarily judged whether it is silver by weighing.
5, check the hardness:
The hardness of silver is low, and the silver ornaments are easily bent and broken by hand, indicating that the color is high. Or use a pin to draw in an inconspicuous place, such as the needle slipping, it is difficult to leave traces on the surface, and it can be judged as a copper ornament; If the object has traces but is not obvious, it can be roughly judged as silver jewelry. This method has been widely used since ancient times. It is often seen in costume movies that people who love money like life bite their teeth when they receive silver dollars. Actually, they are testing the hardness.
6. Use acid:
Silver will change color or even dissolve when it meets any acid. If a drop of concentrated hydrochloric acid is dropped on the inside of silver jewelry, white moss-like silver chloride precipitate will be formed immediately. Other precious metals do not have this phenomenon.

7. Listen to this poem:
The standard silver jewelry sounds dull and inelastic after landing. If it is made of copper, its sound is high and sharp, and its rhyme is short and short;
It is no problem to distinguish the authenticity of silver ornaments by using the above methods comprehensively. If the counterfeiter can achieve perfection, then his cost is much higher than the real sterling silver, and there will be no profit. If consumers want to know the exact content of silver jewelry, they can only go to the jewelry or precious metal testing center for testing, and the cost ranges from 30 to 100.
