990 silver jewelry is very popular in the market, but fakes are also emerging in an endless stream. Some people are often deceived when buying 990 silver jewelry and buy fakes. So how should you distinguish the authenticity of 990 silver jewelry when you buy it? What aspects should you start with to distinguish the authenticity of 990 silver jewelry? How to distinguish the authenticity of 990 silver jewelry1. Color When distinguishing the authenticity of 990 silver jewelry, you can start with the color. 990 silver jewelry has a relatively high silver content and is of relatively high purity. Its color should be evenly shiny and accompanied by polish. If you find that the color of 990 silver jewelry is blue-gray, it means that it contains lead and is not real 990 silver jewelry. 2. Weight To distinguish the authenticity of 990 silver jewelry, you can also start from the weight. From the perspective of metal, silver is the heaviest and aluminum is the lightest. Children's weight is neither light nor heavy. If you hold the silver jewelry in your hand and feel it is heavy, it means it is real 990 silver jewelry. If it feels light, it means it is a fake. 3. Hardness To distinguish the authenticity of 990 silver jewelry, you can also start with the hardness. Because the hardness of silver is relatively low, when people usually use a pin to slide it on an inconspicuous place on the jewelry, there will be slight scratches. If it is found that there is no mark left after the pin is scratched, it means that it is fake silver jewelry mixed with copper. If the scratches are particularly deep, it means that the silver jewelry is impure and contains lead or tin. 4. Sound 990 silver jewelry is a loud sound when it hits the ground, and it has no elasticity when it hits the ground, and it will make a "plop plop" sound. The lower the silver content, the lower the sound. If the sound of silver jewelry is high and sharp when it hits the ground, it means that it is fake silver jewelry mixed with copper. If the sound is dull, it means that it is fake silver jewelry mixed with other substances. |
