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 this color

The higher the purity of silver, the whiter the silver bracelet looks, and the color of the face file is delicate, uniform, shiny and polished. If it contains lead, the tidal flowers emitted by the face file will be blue-gray. If it contains copper, it will look rough, rotten and dry.

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.

If the needle slips, it is difficult to leave traces on the surface, which can be judged as copper ornaments. If it is made of lead and tin, the trace will be more obvious; If the physical object has traces and is not obvious, it can be preliminarily judged as silver jewelry.

6. Listen to the sound

Silver is softer than platinum. If you drop it on a hard object, the silver bracelet will make a faint sound, while other metals will make a clear sound.
