1, look at the purity mark: such as S925, S990, etc., can indicate the purity of silver jewelry.
2, the weight of the ring: the ring is large, light weight, may be fake.
5. Test with concentrated hydrochloric acid.
1. Look at the sign
The density of silver jewelry is relatively large, if the ring looks large, but the weight is very light, it means that the ring may be fake. However, this method can not absolutely determine the true or false of the silver ring, and other methods can be used to assist the determination.
3. Look at the color
Silver hardness is low, hand fold silver jewelry, easy to bend not easy to break, indicating high color. Or use a pin to scratch the inconspicuous place, such as the needle slip, the surface is difficult to leave traces, it can be judged as copper jewelry; If the physical object has traces and is not too obvious, it can probably be judged as silver jewelry.
5. Test with acid
When silver encounters acid, it undergoes a chemical change, producing the chemical silver chloride. You just put some concentrated hydrochloric acid on the back of a silver ring, and you get a white thing that they chemically react with, and you get silver chloride. However, this method is easy to damage the ring, so be careful when using it.
