How can you tell if gold is real or fake?

Whether gold is real or fake can be identified by sound. Throw the ** to the place, if it makes a clicking sound, it will not bounce up, and the fake or very low purity ** The sound of falling on the ground is very brittle, and there will be some aftersound.

Distinguish the true and false gold can look at the color, the color of ** has seven green, eight yellow, nine purple and ten red, if the color and purity do not correspond, it means that the gold may be fake. In addition, the weight of ** is much larger than that of silver, copper, iron and other metals, so the weight of **, silver, copper, and iron metal will be greater than that of **, silver, copper, and iron metals.

How to distinguish whether gold is real or fake, there is a comparison, the traditional method is to say that real gold is not afraid of fire, because the melting point of gold is very high, well, her pen, iron and copper melting point, are much higher, you need to take fire to burn him will not have any deformation, then this gold is real, if it is black, it is fake.

1. Visual inspection.

1. Check the official logo of **. It is generally engraved with 999 or 990, or 10k, 18k, 22k, 24k. Less than 10k is not considered because the content of ** is too low. If you look with a magnifying glass, you'll look more closely.

2. There will be no obvious official purity mark on the ancient ** jewelry.

3. Of course, counterfeit ** jewelry will also have official logos, so further inspection is required.

4. Look for obvious discoloration. Inspect the wear areas on the surface, usually at the edges of the product, and check for discoloration there, if the color fades away and changes to another color, then the product is just gold-plating.

Distinguish by texture. The natural **texture is very soft, if it is a **jewelry with high gold content, if it is easy to deform after gravity extrusion, and the fake one will be very hard.

**It is not a magnetic metal, if it can be attracted by a magnet, it is enough to prove that it is not**.

Check the bite marks after a gentle bite, if the bite marks are deeper, the purity of ** will be higher.

Use unglazed ceramic to scratch gold, if it is a black scratch, it is not**, if it is a gold scratch, it is**.

The higher the purity, the darker the color and luster, which can be distinguished by color, weight, sound, and marking; Weighing the weight, ** jewelry should have a sense of sinking in the hand, fake gold jewelry is light to listen to the sound, the color of more than 99% of the real gold thrown on the hard ground, will make a clicking sound, there is no rhyme and no elasticity.

As the saying goes, real gold is not afraid of fire, put gold on the fire, if it is deformed, it is not real gold.

To distinguish whether gold is real or fake, I think gold must be able to weigh it, and weigh it.

The density of the weight is different from that of other metals, so the weight of the weight is also different from the others.

How can you tell if gold is real or fake? For this specificity, you have to go to someone who has a relevant major, uh understands gold, to consult.

Summary. The first trick: look at the color.

**The higher the purity, the darker the color, and the purity that can show a deep red yellow is generally more than 95%, the **purity of light reddish yellow is between 90%-95%, the purity of light yellow is between 80%-85%, and the purity of blue-yellow is between 65%-70%. The purity of the color blue and white light is generally 50%-60%. So you can tell whether it's true or not from the color.

How to tell if gold is real or fake.

The first trick: look at the color. **The higher the purity, the darker the color, and the purity that can show a deep red yellow is generally more than 95%, the **purity of light reddish yellow is between 90%-95%, the purity of light yellow is between 80%-85%, and the purity of blue-yellow is between 65%-70%.

The purity of the color blue and white light is generally 50%-60%. So you can tell whether it's true or not from the color.

The second trick: weigh the weight. **The density is greater than that of ordinary metals, really**heavy, it feels weighty, and it is fake**light and fluttering, but if it is a hollow bracelet, this method should be used with caution.

The same large **,**copper,** is 40% heavier than **, about twice as heavy as copper, so how to identify the authenticity of **, check it with your hand to see if there is an obvious feeling of falling.

The third trick: look at the hardness. It is understood that the Mohs hardness of human teeth is 6, the relative Mohs hardness of silver is 3, the Mohs hardness of pure copper is 3, and the hardness of iron is 4, and the hardness of many metal materials is relatively low.

Biting with teeth will leave obvious bite marks, but there is no scientific basis for judging authenticity by biting with teeth. The texture is soft, it is easy to deform, and the less impurities, the lower the hardness. More than 97% of the fine-quality ** jewelry, after bending two or three times, wrinkles will appear at the bend, also known as fish scale patterns.

And about 95% of the color of the ** jewelry, bending is more difficult, will feel hard, the fish scale pattern is not obvious, about 90% of the color of the ** is very hard when bending, no fish scale pattern, if it contains more impurities** jewelry, bend two or three times that is broken, if it is made of raw gold, then bend that is, and the section will have obvious sand grains. Therefore, looking at hardness is also a way to distinguish the true from the fake.

The fourth trick: look at the mark. Domestic ** jewelry is engraved with purity marks in accordance with the regulations, such as indicating 24k means that the purity is above and 18k means that the purity is above 75%.

"GF" or "HGP" indicates that it is made of gold plating rather than pure gold. For example, gold rings are located on the inside of the ring, gold necklaces are located near the lock, and most of the gold bars are marked with corresponding indicators on the surface. However, be aware that purity labels can also be faked, and counterfeit products can also have purity labels.

Therefore, the authenticity of gold jewellery needs to be further verified.

The fifth trick: take it to a professional institution for identification.

Hello, there are several ways to distinguish the authenticity of gold:1Observe the color:

Real gold is purer in color and appears bright yellow, while fake gold is duller in color, even with green or red tinges. 2.Measuring density:

The density of gold is comparatively larger, and the density can be calculated by weighing and measuring the volume, and if the density matches the real gold, it is likely to be real gold. 3.Use magnets:

Gold is not adsorbed by magnets, and if it is, it is most likely fake gold. 4.Use of chemical reagents:

Some chemical reagents can be used to test the purity of gold, such as acids, iodine, etc., but this method requires a professional to operate. 5.Seek professional expertise:

If you are unsure about the authenticity of the gold, you can seek an authenticity from a professional appraiser or person to ensure the authenticity of the gold. <>

Kiss, you can't see clearly.

It's like this when it's burned with fire, and it's golden on the inside.

You're not golden, are you?

What was originally something.

A bracelet. Judging from **, it does not belong to gold.
