Silver jewelry itself is very malleable, and its shape is also changeable and diverse. It is no longer pure silver jewelry in our impression. In addition to sterling silver jewelry, there are also black silver jewelry, Tibetan silver jewelry and color silver jewelry. So how do we distinguish the authenticity of sterling silver jewelry?

1.Look at the color of the jewelry: the higher the purity, the whiter the silver, and the jewelry wholesale surface looks evenly shiny and polished. If it contains lead, the jewelry will appear blue-gray; if it contains copper, the surface of the jewelry will appear rough and the color will not be moist.

2. Jewelry weight: The density of silver is slightly larger than that of ordinary metals. Generally speaking, "aluminum is light, silver is heavy, and copper is not light or heavy." Therefore, the weight of the jewelry can be substituted for silver to make preliminary judgment . If the jewelry is elongated and lighter in weight, it can be preliminarily judged that the jewelry belongs to other metals.

3. Check the hardness: Silver is lower in hardness than copper, but larger than lead and tin. You can use a pin to test the inconspicuous parts of the jewelry. If the needle is slippery and it is difficult to leave marks on the surface, it can be judged as copper jewelry; If the grain size is lead and tin, the traces are obvious and prominent; if there are traces on the physical object but not too obvious, it is preliminarily judged as silver jewelry.

4. Listen to the rhyme: the sterling silver jewelry is thrown on the floor with a sound, no elasticity, and the sound is "Por Da Por Da". The lower the color, the lower the sound, and the more pointed and rhyming the sound; if it is copper, the sound is higher and sharp, and the rhyme is quick and short; if it is lead, tin flakes, the sound of throwing the ground is dull and short.
