The four methods of distinguishing gold are as follows: 1, color dislocation The saying goes, gold is "seven green, eight yellow, nine purple, and ten red". The experts believe that the jewelry of 70 % of the gold is yellow, and 80 % of the gold is yellow. 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. 2, 重 重 The proportion of gold is 19.3 grams/cubic centimeter. The color is more related to the proportion. When the proportion is close to 19.3, the higher the pure gold. At 18.5, the gold contains 95%, and the gold contains 90%at 17.8, and so on. As long as the proportion is measured, the color of the jewelry can be seen. But most people can have a sense of precipitation. 3, seeing the rhyme The high -colored jewelry, throwing on the cement floor, there will be dull slap sounds, sound without rhyme, no strength, commonly known as "dead sound". On the contrary, the low -collision gold jewelry is thrown on the cement floor with rhymes and sharp sounds, and a slight jump. 4, test soft and hard The higher the color of the gold jewelry, the softer, and the more elasticity. The real gold bite or the needle will have light marks. High temperature) will not change color afterwards. Low -colored and fake are the opposite. The gold jewelry is divided into 24K (more than 99%of gold content), 22K (91.7%), 18K (75%gold content), 14K (58.33%of gold content), 12K (50%gold content), etc.
