There are six ways to test the authenticity of gold:
. Visual inspection 1. The official logo of the golden gold. Generally, 999 or 990, or 10K, 18K, 22K, 24K. It is not considered lower than 10K, because the content of gold is too low. If you observe with a magnifying glass, you will see more carefully. 2, ancient gold jewelry will not have obvious official purity logos. 3, of course, there will be official signs of counterfeit gold jewelry, so further inspections need to be performed. 4, find obvious discoloration. Check the wear area of the golden surface, which is usually on the edge of the golden products to check the color change there. If the golden color disappears and becomes another color, then this product is just a gold -plated.
. The bromine chemistry test 1. Put the golden products in the alcohol solution for a small meeting. 2. Pour a filter paper sperm solution. 3. At this time, the filter paper becomes gray -purple. 4, drop 4 drops of bromo -A reagent to the filter paper, if the filter paper becomes white, then this gold product is real gold. The test time takes 20 minutes.
. Magnetic test This is a simple test, but it is not a sufficient proof to prove whether it is true gold. You can find a powerful magnet for testing. Gold is not a magnetic metal. If the product is attracted by magnets, it is enough to prove that this product is not gold. However, it cannot prove that it is gold because the product does not respond to magnets, because there are many non -magnetic metals.
. The density test only has a very small metal density exceeding gold. The density of pure 24k gold is about 19.3 grams/ml, which is much higher than other metals. The density test method is sufficient to prove that the product is gold. The higher the density, the higher the purity of gold. Make sure the product has no additional gems. 1. If there is no equipment in this area, jewelry shops can usually do density testing. 2, you can put the golden products in the container full of water, and then test the volume of overflowing water, and then except the weight of the product, which is the density of the golden product. Remember, the ratio of different gold purity has different grams/ml ratio: 14k- 12.9 ~ 14.6 grams/ml 18k gold-15.2 to 15.9 grams/ml 18k platinum-14.7 ~ 16.9 grams/ml 22k-17.7 % to 17.8 grams/ Milliliter.
. Bite test The mininger bite gold to test it. When the Olympic athletes get the gold medal, they will bite the "Gold" medal. How simple this test is. 1, bite a gently. 2. Check the bite marks. The deeper the bite marks, the higher the purity of the gold. , in fact, this is not recommended for testing, which will damage the teeth. What's more, the lead will be given to the gold, and the lead is softer.
. The test method of ceramic scratch 1. Using unlawish ceramics. Without this, you can buy it from a ceramic shop. 2. Cover the gold products with ceramics. If it is a black scratch, it means that the product is not gold. If it is a gold scratch, it proves that the product is gold.

Nitric acid inspection method: Put the gold in a stainless steel container and drop a drop of nitric acid on the gold.

Differential gold requires some experience. Here are only some identification methods. (1) See color: the higher the purity of the gold jewelry, the deeper the color. If there is no gold medal, you can determine the general color according to the following color (based on green gold. The so-called green gold contains only silver ingredients in gold); dark red yellow color is more than 95 %, light red yellow 90-95 % The pale yellow is 80-85 %, the cyan is 65-70 %, and the white light is only 50--60 % white light. The slightly yellow and white are less than 50 %. Generally, Qiqing, Eight Huang, and Jiu Chi can be used as a reference. (2) Type weight: The proportion of gold is 19.32, which is more important than metal such as silver, copper, lead, zinc, aluminum. The volume of gold is more than 40 % heavier than the silver, 1.2 times heavier than copper, and 6.1 times heavier than aluminum. The gold jewelry should have a feeling of sinking in the hand, and the fake gold jewelry feels lightly. This method is not suitable for gold jewelry inlaid. (3) Look at the hardness: pure gold is soft and low. It can draw light marks with nails. Teeth bite can leave tooth marks. High -colored gold jewelry is low in color. The bending method can also test the hardness, the pure gold is soft, it is easy to bend, the lower the purity, the less likely to bend. (4) Listening to the sound: Throwing the real gold with more than 99 % to throw it on the hard ground, it will make a tap sound, there is no rhyme or elasticity. The fake or low golden sound is crispy but no dullness. Generally, the sound of "Dangdang" is emitted, and there are surplus sounds. (5) Burning with fire: Burn the jewelry to burn red (do not melt the jewelry) with the fire (do not melt the jewelry), and observe the color change after cooling. The degree of darker is not pure gold. Generally, the lower the color, the stronger the color, and the darkens are all, indicating that it is a fake gold jewelry. (6) Seeing the mark: Domestic gold jewelry is all prepared according to international standards, and the killing records, such as "24K" indicate "foot red" or "foot gold"; 18K gold, "18K", indicate "18K" Words, those who are lower than LOK, can not play the K -printed number according to regulations. At present, illegal elements are commonly used to manufacture fake cards and imitation stamps in the society. They use rare gold, Asian gold, and even brass to impersonate real gold. Therefore, the identification of gold jewelry must be comprehensively determined according to the sample to determine the true and false and the quality of the real.
Look at the authenticity of Zhou Dafu, pay attention to the following:
If the jewelry, first see if the inner wall is engraved with a factory name (Chow Tai Fook), or the content of the content (such as 24K/Age Gold/Football); See if the fire becomes black. As the saying goes, the real gold is not afraid of the fire. If it turns black, it may be impure or there is a solder point if it is false. The goldstone is the golden stone. Generally, there will be a pawn business, and gold has been on it (like a pencil like a pencil) to see the color of the strip marks
From the official website of Zhou Dafu Gold, it is learned that in the gold jewelry, the pure gold jewelry texture is softer, the teeth are bite, and it is easy to bend. The color is golden, pure, soft, heavy, and a heavy feeling. K -gold's head jewelry texture is slightly harder, the teeth bite the use of mintes, the color is yellow in yellow, and the number of K is reduced, the white increases, and the yellow is shallow. The feel of K gold jewelry is not as heavy as pure gold jewelry. In addition, both pure gold and K gold jewelry have a printing sign. Printing on gold jewelry is used "gold" and "KG" English letters represent the texture. When indicating the gold content, the word "99" or "24K" indicates that it is pure gold jewelry. The K gold jewelry is marked with the corresponding K number, such as the K gold jewelry marked "18K". %. In addition, the jewelry also marks the printing of the origin of different manufacturers. Really gold jewelry, printing standards, completeness, and clear, is an important identification of judgment.
The official website of Weekly Dafu Golden Point specifically pointed out that paying attention to distinguishing gold plating jewelry. Gold plating jewelry is plated on the surface of other metal jewelry on the surface of the electroplating method. The color is similar to the real gold jewelry. The golden light is bright, and it is difficult to recognize. However, the gold -plated jewelry feels lightly, the texture is hard, the teeth are bitter, and it is easy to fade with a long time. Whether it is gold -plated jewelry, gold jewelry, copper jewelry, and Asian gold jewelry, it generally does not have a printing sign similar to gold jewelry. Or it is different from gold jewelry. If some jewelry is engraved with the English letters "GK", it means "gold plating". Or the signature traces are blurred and crooked. Consumers should identify whether there are printing, printing whether the printing is in compliance with the above provisions, and whether the printing is clear, etc. to determine the authenticity of gold jewelry.
There are six ways to test the authenticity of gold:
