Sterling silver jewelry fell to the ground and was not elastic. The lower the color, the lower the sound, and the sharper and higher the rhyming sound; If it is made of copper, its sound is high and sharp, and its rhyme is short and short; If it is made of lead and tin, the sound is dull, short and inelastic.
The density of silver is slightly higher than that of ordinary metals. Generally speaking, "aluminum is light, silver is heavy, and copper is not light or heavy." Therefore, it can be preliminarily judged whether it is a silver ornament by weighing. If the silver bracelet is large in size and light in weight, it can be preliminarily judged that the silver jewelry is not genuine.
The hardness of silver is lower than that of copper, but higher than that of lead and tin, so it can be tested by making a mark on the inconspicuous place of the silver bracelet with a pin. For example, if an inconspicuous place is scratched with a needle, for example, if the needle slips and it is difficult to leave traces on the surface, 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. In the movie, we saw that the ancients first bit the silver dollar with their teeth, but they were actually testing the hardness. If it is made of lead and tin, the trace is obvious; Easy to bend, high color that is not easy to break by hand; Stiff, or barely bent, and some can't even bend with their fingers. Silver-plated jewelry will crack if it is bent or knocked a few times with a hammer; What can't stand bending and break easily is fake.
If you still can't distinguish the above methods, you can also send them to the jewelry testing center for testing, but the charging of the testing center is not cost-effective; Because silver jewelry is of low value. It is recommended to buy silver jewelry, preferably in the specialty stores of big brands.
