I bought a silver comb for my trip. How can I tell the truth quickly and accurately?

first, look at the color: the higher the purity, the whiter the silver, and the jewelry surface looks even, shiny and polished. If it contains lead, the jewelry will appear bluish gray; If copper is contained, the surface of jewelry will appear rough and the color will not be moist.

second, balance weight: the density of silver is slightly higher than that of common metals. Generally speaking, "aluminum is light, silver is heavy, and copper is neither light nor heavy." Therefore, a preliminary judgment can be made whether it is silver by weighing it. If the jewelry is large in size and light in weight, it can be preliminarily judged that the jewelry belongs to other metals. Hardness check: the hardness of silver is lower than that of copper, but higher than that of lead and tin, so it can be tested by marking the inconspicuous place of jewelry with a pin. If the needle slips and it is difficult to leave traces on the surface, it can be judged as copper jewelry; If it is made of lead and tin, the trace is obvious and prominent; If the physical object has traces but is not obvious, it can be preliminarily judged as silver or jewelry.

third, listen to the rhyme: hit the floor, a sterling silver ornament, has no elasticity and the sound is "boo boo boo". The lower the color, the lower the sound, and the sharper and higher the sound with rhyme; If it is made of copper, its sound is higher and sharp, and its rhyme is short and short; If it is made of lead and tin, the sound of throwing the ground is dull, short and inelastic.

it is not an ideal method to test silver only by its physical properties and experience. Only by destroying the silver ornaments can the authenticity of the silver ornaments be tested by chemical methods. However, this is beyond the reach of consumers. When buying silver jewelry, consumers should not only master some basic inspection knowledge, but also pay attention to whether there are relevant certificates, certificates and certificates for silver jewelry. Only silver jewelry that has been tested by testing institutions can be bought with confidence.

In addition, the silver content of silver jewelry must be accurately marked, and consumers should check whether there is "S925" on the jewelry when they buy it. "S" is the first letter of the English word for silver, and "925" is the symbol of pure silver. As long as you have "S925", you can ensure that you are buying genuine sterling silver jewelry. Pay special attention to whether its fasteners can be fastened and secure when buying. When buying a silver chain, put it flat to see if the links are kinked or bent. The price of silver jewelry is determined according to the content of precious metals, structural design and craftsmanship, so the most important criterion for choosing silver jewelry is whether you like it or not.
