After a long time, the color will become dull. - " The color of chemical gold is often too saturated, and it is different from the natural color change of gilded gold. 2. ** Quality * - [Gilded gold: It really contains a lot of copper and has a certain weight.] - [The chemical gold: The copper content may be different from the gilded gold, and the weight may not be as heavy as the real gilded gold.] 3. ** In terms of taste ** - [Gold gilding: There will be smoke or mold smell.] - [For chemical gold, there will be a chemical corrosive smell.] 4. ** Judging from the gilded part ** - Gilding: Most of the gilding was only applied to specific parts.

Here are some ways to identify gold: 1. ** Observe the color and stamp **: Gold with a purity of more than 95% is rich and bright. The lower the purity, the lighter the color and may be accompanied by other colors. For example, gold with less than 50% purity would turn white or white, and gold with 50% - 60% purity would only have a faint yellow color. At the same time, he checked the steel seal. If it was printed with 999 gold or 999 gold, it meant that the purity of the gold was 999/1,000. 2. ** Hardness Test **: Gold is soft and has a low hardness. You can use a hard object such as a sewing needle to gently scratch the gold (3D hard gold is not suitable for this method). If there are obvious traces, it may be real gold; if it is not scratched or the surface is very hard and there are no traces, it may be fake gold or very low purity gold. 3. [Listen to the sound: Drop the gold from a certain height or place a small gold accessory on a plate to listen to the sound.] The sound of real gold was dull and would not bounce back when it fell to the ground, while the sound of fake gold was clearer, and if it was a larger piece of fake gold, it might bounce back. 4. [Fire Burning Method: True gold is not afraid of fire, but you need to pay attention to burning it with a flame above 1000 degrees.] Normal gold jewelry would turn red or melt at most during the burning process. The color would become yellow and bright, and the grams would not decrease. After cooling, the color would not change. If there was blackening, ash, smoke, odor, etc. during the burning process, it proved that there were impurities or fake gold in the gold. 5. ** Professional instrument testing **: Professional instruments such as the density law gold tester and the fluorescence spectrum gold tester can accurately determine the purity of gold jewelry and whether it is real gold. 6. ** Chemistry test **: Put the gold in 25% dilute sulfuric acid. If there is no reaction, it may be real gold. If there is a reaction, such as white bubbles on the surface, it may not be real gold. However, this method needed to be done carefully, and it was best to do it under the guidance of a professional.
Here are some ways to distinguish between real and fake gold: 1. ** Check the seal **: The circulation of gold is strictly controlled. The seal has legal effect. If there is no seal, it will be regarded as a substandard product. However, gold below 10 grams may not be stamped with a seal. However, he had to be careful that the seal could also be fake. 2. [Weight by hand: The weight of gold is much greater than other metals. For example, pure gold the size of a matchbox weighs about a pound, while silver or copper is less than half the weight of gold. Experienced people can roughly determine it by hand.] 3. [Light Pulling Test: Gold is soft. The higher the purity, the better the malleability. It can be lightly pulled to test. In the past, folk craftsmen would also use their teeth to confirm it.] 4. Stripe method (touchstone method): In the past, the folks used touchstones to compare the measured object with the standard plate to determine the quality of gold. An experienced master could control the error within 5%. 5. ** Acid Point Test **: Gold does not easily react with any single acid. Dip a glass rod in a little sulfuric acid and point it on the tested object. Gold will not change, silver will turn black, and copper will emit green bubbles. 6. [Fire observation: True gold is not afraid of fire. Pure gold will burn red in the fire without any change in color, while K gold will turn black.] 7. ** Sonic Bounce **: The sound of gold falling to the ground is slightly dull and has no rhyme. It is commonly known as the sound of death, unlike other metals that have a clear sound. Moreover, when it falls to the ground from about one meter away, it usually bounces no more than three times. If it bounces more than three times, it might be fake or not pure enough.
The authenticity of rose gold can be distinguished by the following methods: 1. ** Look at the luster **: True rose gold has fine craftsmanship, tight structure, and bright luster; fake rose gold has rough craftsmanship, loose structure, and poor luster. 2. ** Hardness test **: The real rose gold has a moderate synthetic ratio, strong malleability, high hardness, variable color, and is not easy to be deformed or scratched. The fake rose gold is soft or very hard. 3. ** Look at the stamp **: Rose gold is mostly made of 18K gold. The surface of real rose gold jewelry usually has "G750","18K","Au750" and other markings.
