Jewelry wholesale tells you how to distinguish the purity of silver jewelry

For silver jewelry, the most important thing is its purity! Why do you say that! Because purity is related to its quality, it is closely related and inseparable, so how do we distinguish the purity of silver jewelry! Let the author of Jewelry Wholesale come to talk to us.　　Method 1　　 look at the label: According to national regulations, the silver content of silver jewelry must be accurately marked. Consumers should check whether the jewelry has a purity label S925, Ag925, or S990, Ag990 (traditional bracelet child lock). If there is no label, it can basically be concluded that it is ordinary metal.　　Method 2　　Look at the color: the higher the purity of silver, the whiter the color of silver. Generally, the surface of pure silver jewelry looks evenly shiny and polished. The lower the purity, the more likely it is to appear greenish gray or rough in appearance.　　Method 3　　weight: Silver has a high density and is heavier than ordinary metals. It is said that 'aluminum is light, silver is heavy, and copper is unclear and not heavy.' Therefore, the greater the purity of silver, the greater the weight.　　Method 4　　Check the hardness: Silver has low hardness. Fold the silver jewellery lightly by hand, which means that it is easy to bend and not break, which means that the color is high. Or use a pin to draw an inconspicuous place, such as a slippery needle and it is difficult to leave marks on the surface, it can be judged as a copper ornament; if there are traces on the physical object but not too obvious, it can be judged as a silver ornament.　　Method 5　　Use acid to be true: Silver will change color or even dissolve when it encounters any acid. If a drop of concentrated hydrochloric acid is dripped on the inside of silver jewelry, a white moss-like silver chloride precipitate will be formed immediately. But other precious metals do not have this phenomenon.　　Method 6　　Listen to the sound: To distinguish the purity of silver jewelry, you can perform a sound test. When throwing a sound, it will make a heavy and crisp sound, and the purity of silver jewelry without elasticity is high; on the contrary, the lower the purity of silver, the lower the sound.
