How to identify a thousand pure gold, is a thousand pure gold real gold?

Draw on the touchstone, seven green, eight yellow, nine purple, and ten red. It can also be cremated to see that there are no impurities and is shiny.

Gold is also known as pure gold, and the gold content is not less than

Thousands of pure gold is the national metal gold content of the mark!

Pure gold is only a registered trademark, not the gold content of the metal.

9999 is currently nationally recognized. I don't know what 99999 is, it is said that the gold content is higher, but the merchant has the final say. The state does not recognize its gold content to this extent!

1. Debate color: As the saying goes, ** is "seven green, eight yellow, nine purple, ten red", experts believe that the gold content of **jewelry is seventy percent, the color is yellow with green, the gold content is eighty percent, the color is yellow, the gold content is ninety, the color is yellow with purple, the gold content is ten percent, and it is red.

2. Concern: **It is the largest specific gravity in the known substance, and the color is proportional to the specific gravity, so ordinary people can also try it out by weighing the weight.

3. Listen to the color: those with high gold content will have a dull clicking sound when thrown on the cement floor, with sound but no rhyme, no strength, commonly known as "dead sound". On the contrary, the ** with low color is thrown on the concrete floor with rhyme and long sound, and jumps back slightly.

4. Test soft and hard: the higher the fineness, the more inelastic, real gold will leave light marks with teeth and acupuncture, and there will be no broken lines in one hand, and it will not change color after fire (not extremely high temperature). The opposite is true for the low and false **.

5. Look at the logo.

In daily life, there are some simple and easy specific methods to identify the authenticity of ** jewelry, which are introduced as follows:

1) Fire burning method: "Real gold is not afraid of fire", after the jewelry is cooled by high temperature fire, ** is still golden yellow and not deformed, which is the saying "fire is afraid of real gold". If it turns black, it is not real gold or has other metals mixed with it.

2) Eyesight method: ** has a dazzling red yellow, their luster and color are enduring and durable, the lower the fineness, the worse the color, that is, people often say "seven green, eight yellow, nine red". It can be identified from the color of ** jewelry with other metal pseudonyms.

3) Ear Hearing: Listening to sound to distinguish components. If the jewelry falls naturally from a high place, if it makes a "horn" sound, and there is no rhyme and no elasticity, it is a higher purity**. If the sound is long and elastic, it means that its fineness is not high, and the jewelry contains more other metals.

4) Hand Weighing Method: Compare the weight with your hand. The specific gravity is much higher than that of silver, copper, tin and other metals, and by comparing the weight, it can be identified whether it is counterfeited with other metals** jewelry, because the same volume is much heavier than silver, copper, aluminum, etc.

5) Tooth bite: **The hardness is low, relatively soft, and there will be traces when biting with teeth. Other imitation gold does not have this characteristic, and the higher the fineness, the softer. Good luck, happiness, and fortune!

Marked pure gold is true.

Pure gold 999 means **jewelry**reaching. And we generally call the ** jewelry with a gold content of 99% as pure gold, so the meaning of marking pure gold is that the ** content of this **jewelry is more than 99%.

The latest regulations clearly stipulate that ** jewelry is only allowed to be called "pure gold". The state has cancelled the title of 1,000 pure gold, and uniformly stipulates that the goods with ** content and above are uniformly marked as pure gold. The ** jewelry sold on the market will no longer have the title of "thousand pure gold", and all will be unified as "pure gold".

**Purity classification:

According to the definition of the national standard, ** is divided into the following types, and the minimum value of the purity thousandth is expressed as . Other expressions of purity are: 9k, 14k, 18k, 22k, pure gold, and pure gold.

For jewelry, the national standard is only defined as 1,000 pure gold.

18K gold represents the content of ** is 18 24, that is, 75%, and the remaining 25% is other metals, usually copper, ** and so on in gold jewelry. 24k gold means pure gold.

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.
