1, professional organization testing Many people say that if you buy gold, you can test it yourself first, for example, to see the hardness of gold jewelry, for example, to test whether gold jewelry is easy to fade and so on. But these are generally understood by more professional people. Ordinary people may not have such a strong sense of screening. Therefore, I suggest that ordinary people, if they want to identify the authenticity of gold jewelry, the best way is to turn to professional institutions for testing. For example, if you buy gold jewelry, you need to see whether the gold jewelry has the certificate of professional organization testing. Of course, you should learn to distinguish the authenticity of the certificate. Generally, if the gold jewelry has a certificate tested by a professional organization, and the certificate is true, then the quality of the gold jewelry should not be too big a problem. Of course, if you have bought gold jewelry but you are still not at ease, you can also take the gold jewelry you bought to a professional institution for testing to see if there is any problem with the quality of the gold jewelry. If there is a problem, take the receipt and apply for a return or exchange.
2, personal testing According to common sense, if you buy gold jewelry purely for wearing, then you only need to test the authenticity, because the gold content of these things, you generally can't detect it. For example, the gold shop says that the gold content of the gold jewelry you bought is 99.99%, so you need to go to a professional institution to test and confirm it. According to common sense, ordinary individuals can basically detect the authenticity of gold by looking at color, weighing and hardness testing. Because gold is generally golden yellow and basically does not fade; If you weigh it, it may be about 5 grams like a ring. If it's heavy, it means there are other ingredients. As for hardness test, gold is soft. If you think it's hard, don't buy it, either the gold content is not high or it's fake.
