How to check the authenticity of silver necklaces, how to identify the authenticity of silver neckla

Self-identification can be done in the following ways:

1.Look at the indicators. According to national regulations, the silver content of silver jewelry must be accurately marked, and consumers should check whether there is a mark on the purity of the jewelry S925, AG925 (fashion is more common), or S990, AG990 (traditional bracelet child lock).

If it is not marked, it can be concluded that it is a common metal.

2.Check the hardness. The higher the color of silver jewelry, the softer the texture, and the whiter and smoother the surface.

Take a silver bracelet of about 60 grams as an example, if it is opened by hand, there is no elasticity, and its fineness is about 95%; If it is a little elastic, the fineness is about 80% 90%; If the elasticity is large, the fineness is less than 70%.

3.Look at the color. The higher the purity, the whiter the silver, and the surface of the jewelry looks evenly shiny and polished. If it contains lead, the jewelry will take on a blue-gray color; If copper is contained, the surface of the jewelry will appear rough and the color will not have a sense of moisture.

4.See**. At present, the Shanghai **Exchange** is about 5 yuan per gram, which does not add procurement costs, process costs, etc., if the **low is outrageous, it must be not pure enough or fake.

5.Weigh the weight. **Slightly denser than common metals, in general:

The aluminum is light, the silver is heavy, and the copper is not light and not heavy. Therefore, the weight can be weighed to make a preliminary judgment on whether it is **. If the jewelry is large in size and light in weight, it can be preliminarily judged that the jewelry belongs to other metals.

6.Solid with acid. Silver can change color and even dissolve when exposed to any acid. If a drop of concentrated hydrochloric acid is placed on the inside of the silver jewelry, a white moss-like silver chloride precipitate is immediately formed. This is not the case with other ***.

7.Throwing method. The silver jewelry with high fineness is heavy, and it is not high to jump on the table, and there is a "pop" sound; Fake or low-quality ones are light, and they bounce very high on the table, and the sound is relatively crisp.

8.Bending method. Pinch the bend with your fingers, the high color is soft and flexible, easy to bend and not easy to break; The quality of the bending is harder, or barely bold, and some can't even be bent with fingers; The silver-clad will crack when bent or struck with a hammer; The fake one can't withstand bending and is easy to break.

9.Listen to the rhyme. The sound of standard silver jewelry is dull and non-elastic after it lands. If it is copper, its voice is higher and sharper, and the rhyme is rapid and short.

Normally, see if there is a steel seal, if not, you can use the method of fire.

Burning it with fire and turning white is true.

1. Look at the color of hunger. The higher the purity, the whiter the silver, and the surface of the necklace looks evenly shiny and polished. If it contains lead, the necklace will be rotten and blue-gray; If it contains copper, the surface of the necklace will appear rough and the color will not be moisturized.

2. Weigh the weight. **The density is slightly larger than that of common metals, and if the necklace is larger and lighter, it can be judged that the necklace is other metals. On the contrary, if there is a heavy feeling, it means that it is a real silver necklace.

3. Check the hardness. **The hardness is lower than copper, and larger than lead and tin, and can be tested in an inconspicuous place where the necklace can be drawn with a pin, if the needle is slippery, it is difficult to leave traces on the surface, it can be judged as copper jewelry; If it is lead and tin texture, the traces are obvious and prominent; If there are traces in the physical object and it is not obvious, it can be preliminarily judged to be **.

4. Listen to the rhyme. Throw the silver necklace to the ground, listen to the sound of the silver necklace, if the sound is low, it means that it is a fake silver necklace, otherwise, it means that the silver necklace is **.
