How to distinguish the real from the fake How to tell the real from the fake from the fake

**The identification method is as follows:1Bite method.

The bite can be used to identify**. ** is a very soft metal. The high purity of ** has low hardness, and tooth marks will appear after being bitten.

If the color is low, the content of other metals is high, the hardness will be relatively high, and there will be no traces when biting with teeth. 2.Combustion method.

In addition, ** can also be identified by the combustion method. The ** with higher color will not change color after firing, and the color will get better and better. Due to the high content of other metals, the ** with color difference will turn black and discoloration after combustion, and the gloss will deteriorate.

3.Hand weighing. **It can also be identified by hand weighing.

**The highest specific gravity is in metals, with a specific gravity of 19:37. Therefore, the ** of the same volume will be much heavier than silver, copper, iron and other metals.

When you weigh the ** with your hands, you will have a strong sense of falling.

First, look at the word print.

If it is a finished jewelry, each piece will have a pure gold, or a thousand pure gold word prints, which is the national regulations ** jewelry needs to be printed, mainly to go to a regular jewelry store to buy, plus look at the word print, generally sure to be true. But there is a problem, that is, whether the content can reach pure gold or 1,000 pure gold, it is not visible, this method can only rely on the trust of regular jewelry stores.

2. Weighing.

**The density is, so a little bit, it has a sense of heaviness, if it is fake, there is no sense of heaviness, if a **jewelry looks very large, it feels like there are 10 grams, but it is only 1 or 2 grams when it is weighed, then this **jewelry may be fake.

3. Look at the hardness.

The hardness of ** is very soft and malleable, so the general gold chain is easy to tear off, but the broken mouth is not so crisp, there will be a feeling of connection, just like a sandwich biscuit broken feeling, the fracture is not Qi, this is caused by the ductility of **, this method is also to rely on experience to determine the truth or falsehood, people who do not understand is not suitable for use.

Fourth, burn with fire.

This is a fire of professional jewelry to grab the ** after it is melted and cooled, a very bright golden yellow color appears, which is the real **. If there is a little rustle or dull golden yellow after melting and cooling, it may be that the content of ** is not enough and does not reach 99.

Fifth, use the machine to measure.

With a professional detection machine, to detect the content of **, this method requires professional equipment and professional personnel to operate.

1. Whether there are white bright spots. Cut the gold bar or gold jewelry with material scissors, observe its cut surface with a magnifying glass, if you see white bright spots, because ** and iridium cannot be fused together, it means that the ** is mixed with iridium.

2. Measure the specific gravity. Measure the weight of a pure gold bar with a balance, then place the bar in a measuring cup and pour water over the bar. Then put the gold bar to be tested into the measuring cup, observe whether the scale of the water rises or falls, as long as it changes, it means that the gold bar is not pure gold.

However, this method does not apply to gold jewelry, because there is air in it.

3. Real gold is not afraid of fire. Put the gold bars or gold jewelry on the fire for a while and observe the changes. Because iridium will oxidize with oxygen in the air, gold bars of insufficient purity will turn gray; Pure gold, on the other hand, will be red and shiny in color after being roasted by fire.

However, this method may be destructive to jewelry.

1. You can bite with your teeth.

When you are watching TV, you must have seen such a shot, that is, use your teeth to identify the authenticity of **, because the texture of ** is relatively soft, and tooth marks will appear when biting with teeth, if there are no tooth marks, it must be fake**.

2. Burn with fire.

As the saying goes, "real gold is not afraid of fire", that is to say, it is true that it is not afraid of high temperatures, the melting point of ** is more than 1,000 degrees, it can be burned with fire**, and it will not change color if there is discoloration or melting.

3. Listen to the sound.

When tapping**, the real** will make a "poof, poof" sound, while the fake** sound will be more brittle, generally a "dangdang" sound.

Fourth, ceramic scratch test method.

Use unglazed ceramic. Scratch the **product** with ceramic, if it is a black scratch, it means that the product is not**, if it is a golden scratch, it proves that the product is**.

5. Magnet test.

It's a simple test, but it's not a sufficient proof of whether it's real gold or not. You can find a strong magnet to do the test.

**Not a magnetic-containing metal, if the product is attracted to a magnet, it is enough to prove that this product is not**. But just because the product doesn't react to magnets doesn't mean it can't be proven, because there are many non-magnetic metals.

Teach you the tricks to distinguish the real from the fake, simple and fast, and you are not afraid of being deceived when you buy gold jewelry in the future.

First, you can look at the color of **. **The higher the purity of the jewelry, the darker the color. In the absence of a gold medal, the general fineness can be determined according to the following colors (based on lapis and gold.

The so-called lapis gold is only contained); The color of dark red yellow is more than 95%, light red yellow is 90-95%, light yellow is 80--85%, blue yellow is 65-70%, the color blue with white light is only 50-60%, and the yellowish and white is less than 50%. The commonly said seven green, eight yellow, and nine red can be used as a reference.

Second, burn the jewelry and observe its color change after cooling. If it is pure gold, the surface will still be golden yellow after burning. If the color is black, it is not pure gold. However, when burning, pay attention to observation and do not burn the jewelry.

Third, listen to the sound. Dropping solid gold jewelry on the ground will make a clicking sound. The fake or bad ** will make a dangdang sound when it falls to the ground, and it will beat after landing.

Fourth, bite gently with your teeth. In ** jewelry, pure gold jewelry has a soft texture, teeth bite with marks, easy to bend, the color is golden, pure, soft, heavy feel, heavy feeling, the color is yellow with white, white gradually increases, yellow gradually lighten. K gold jewelry is not as heavy as pure gold jewelry.

Gold-plated jewelry, on the other hand, is plating a layer of gold on the surface of other metal jewelry.

The color is similar to that of real gold jewelry, golden and shiny, and it is difficult to identify when it is new. However, gold-plated jewelry feels lighter and floating, the texture is harder, and there is no mark on the teeth, and it is easy to fade after a long time. Some gold-plated jewelry with poor electroplating is either red or whitish in color, or flowery.

Summary. There are many ways to tell if gold is genuine, including visual inspection, radioactivity testing, and metalworking testing. Authenticity can be judged by inspecting appearance characteristics such as color, brightness, cleanliness, and weight.

In addition, radioactivity detection is an effective means of detection, which can determine the quality of gold; Metalworking testing, on the other hand, is able to physically analyze gold to determine whether it is genuine.

I'm still a little confused, can you be more detailed?
