    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. 量 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 -quality gold jewelry is lower than the soft 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. Listen 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: The jewelry will be burned red with fire (do not melt the jewelry), and observe the color change after cooling. Black 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 allicized and prepared according to international standards, and the killing records, such as "24K" indicate "foot red" or "foot gold"; 18K gold, the word "18K" is marked For those who have a color lower than LOK, the K gold printed number cannot be played 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 hardness. High -colored gold can leave traces with large head needles or nails. More than 97%of the gold jewelry, after two or three times, wrinkles appeared at the bend, also called fish scales; about 95%of gold jewelry, it feels hard when bending, and the fish scales are not obvious; The jewelry is very hard when the bending is bent, and there is no fish scale pattern; the gold jewelry containing more impurities, the bend is twice or three times to break;nListen. The real gold with more than 99%of the real gold is thrown on the hard ground, and it will make a sound, there is no rhyme or elasticity. The fake or low golden sound is crispy but no dullness. Generally, the sound of "Dangdang" is made, and there are surplus sounds. The proportion of gold is 19.3g/cm3, which has a large relationship with the proportion. When the proportion is close to 19.3, the higher the pure gold. Looking at whether it is commensurate with the size of the size, the shape is large and lighter may be adulterated. But generally in the hands, if you feel slightly sinking, you can perceive the real gold jewelry, which shows that the gold body is small and heavy. You should be vigilant for the stupid and light jewelry, and carefully discern whether for fakes or semi -fakes. Try softness. The higher the color of the gold jewelry, the softer, and the more elasticity. The real gold will have light marks with teeth or needle. Low -colored steel is hard; those with heavy mixes are elastic, crispy and easy to break. The pure gold is soft, and it is generally not used to make embedded jewelry. Therefore, all inlaid gold jewelry claims to be 24K and there must be fraud. Scraping porcelain plate method. Find an unsightly porcelain plate.
