  1. Differential gold requires some experience. Simply introduce some identification methods. But it is best to go to the gold shop!

    (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 prints. High -colored gold jewelry is low and soft, with copper with copper, contains copper containing copper, contains copper containing copper The harder, the harder, 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: Real gold with a color of more than 99 % throwing 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 (do not melt the jewelry) with fire (do not melt the jewelry), and observe the color change after cooling. Dark or different degrees of darkness 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"; The word "18K" is marked, and those who have a lower color are lower than LOK. 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.

  2. If you are not at ease to go to the good and good reputation of the serious store, let them write down the quality of the product to you. If it is not what they say to deal with it,
    Law. It is best to burn and wait for him to cool down naturally. As long as the golden content of the golden belt is not black, the good gold will be cracked in the middle after cooling. It can be used as a mirror except for the fissure. If the first two points are reached, the content will not be less than 98%, but it is not that ordinary people do not understand. The appearance light is not smooth to determine the golden color, but some gold surface is smooth but the color is still not high, because the material contains different substances. For example, the silver contains the color, but the color will be reduced. If copper -containing, it will be black. But it can be said that it is definitely impure. Most of the appearance of the film contains a certain welded, and the finished necklace of the gold shop will definitely have a membrane on the surface after melting. But the overall color will also be more than 98%(famous brand manufacturers). As for hanging water, it is not a very accurate unit error of about 1%. If the appearance is not good -looking, it can be recovered at the full price of the recovery price of 99%. 99.99%of the price is impossible. Essence It is enough to reduce the price of 5 yuan at a gold transaction price. But some places can't get this price.
