  1. The identification of the authenticity of gold and its skills as follows:
    1, the naked eye observation method
    In the finding the official logo. In the sign, the purity of gold (1-999 or 0.1-0.999) or the number of carats (10K, 14K, 18K, 22K or 24K) is used. It may be worn, and fake gold may also be marked because further verification is needed.
    2. Whether the gold device fades.
    The check where the gold ware is easy to wear (especially the edge) is the phenomenon of fading. The device may be just gold -plated.
    3. Whether there is a bite mark on the gold device
    Theoretically, the real gold will leave the bite marks after being bitten. The deeper the bite marks, the higher the goldenness of the gold, but we do not recommend this method. Because this may hurt the teeth. In addition, because lead is softer than gold, bite marks will be left on the gold -plated lead.
    4, weighing
    If you do n’t have a balance, you can ask you to say it on your jewelry, it is usually free. The weight should be accurate to gram, filled with water in a small bottle. If there is a millimeter scale on the wall of the small bottle, it will help you to complete the test more conveniently. It's okay, so don't pretend to be full. After putting in the golden device and after being put into the gold, you must carefully write down the height of the water level.

  2. 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 be used to draw light marks with nails. Teeth bite can leave dental marks. High -colored gold jewelry is low in color. It can also test hardness, pure gold is soft, 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 % of the color 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.
