The method of distinguishing the authenticity of gold is as follows: 1. Seeing the 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 the golden gold as the criterion, the so-called green gold is only a silver component in the gold), the dark red yellow color is more than 95%, and the light red yellow yellow 90-95% The pale yellow is 80-85%, the cyan is 65-70%, the color blue with white light is only 50-60%, and the slightly yellow and white are less than 50%. 2, 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 light. This method is not suitable for gold jewelry inlaid. 3, see hardness. It pure gold and low hardness. Use nails to draw light marks. The teeth can leave the dental marks. The high -quality gold jewelry is lower than the soft color. Test hardness, pure gold is soft, easy to bend, the lower the purity, the less likely to bend. 4, listen to the sound. The real gold with a color of more than 99%to throw it hard on the hard ground. 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 to burn red (do not melt the jewelry) with fire (do not melt the jewelry), and observe the color change after cooling. 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, see 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", the color is lower than 10K, which is less than 10K Those who can not play K gold printed in accordance with regulations. Criminals in the society are commonly used to make fake licenses and imitation stamps, and 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. 7, instrument detection. It, no matter where, X -ray fluorescent analyzer can complete a large amount of golden purity test tasks every day. This technology does not need to damage samples, almost no need to prepare samples, and can provide reliable results in a few seconds. This means that the tedious preparation of the laboratory testing method is also avoided by the uncertainty of artificial judgment and can obtain accurate analysis results at any time.

According to the different gloss and color of gold, you can generally distinguish pure gold, K gold, real gold, fake gold. That is, gold is better yellow (yellow -red), and the color is more than 95%; the positive yellow color is about 80%; the blue and yellow color is about 70%; the yellow color is slightly gray and the color is about 50%. Therefore, there is a formula for "seven greens, eight yellow nine five red, yellow leucorrhea ash pairs of gold". For jewelry from Jiu Tibet, there will be a saying that "copper turns green, silver turns black, and gold will never change color".
