There are several ways to distinguish gold:
The first method: _ vinegar clock. I am good at learning English, and I am also good at returning to the curtain. At night, the gun rang and the clock rang. Hao Ying is jealous of Xia Zhong when overseas Chinese make trouble with delicious food. Fan Qinxian's description: 5. I am afraid to relax my mind, I am afraid of suffocation, I am afraid I am afraid I am afraid I am afraid I am afraid I am afraid I am afraid I am afraid I am afraid I am afraid I am afraid I am afraid I am afraid I am afraid I am afraid I am afraid I am afraid I am afraid I am sorry.
The second method: weighing, the density of gold is 19.32, so a little bit, there is a heavy feeling, if it is fake, there is no heavy feeling. If a gold ornament looks big and feels like 1 0g, but in fact it is only1or 2g, then it may be fake. This method is based on experience.
The third way to look at the hardness: the hardness of gold is 2.5, which is very soft and malleable, so the general gold chain is easy to break, but the broken mouth is not so brittle, and there will be a feeling of connection, just like the feeling that the sandwich biscuit is broken, which is caused by the ductility of gold. This method is also based on experience to judge whether it is true or not, and it is not suitable for people who don't understand.
The fourth way is to use fire: this is to rob gold with the fire of professional jewelry. After melting and cooling, it will appear bright golden yellow, which is real gold. If there is a little rustling or dull golden color after melting and cooling, it may be because the gold content is not enough and it does not reach 99. This method is also suitable for experienced people to operate. Inexperienced people can use it, but they can't tell how much is in it.
The fifth method is machine measurement: the gold content is detected by professional machines. This method requires professional equipment and professionals to operate.
The sixth method is to go to a professional institution for appraisal: professional testing institutions are actually similar to the fourth method. It is also a professional person who uses a professional machine to measure the gold content, but can issue a certificate, which is what we often call a certificate.
Precautions:
1. Pay attention to asking for an invoice when buying gold online.
2. Don't trust and buy gold ornaments whose online price is ridiculously lower than the market price, and don't be fooled by the low price. For example, a big gold chain costs several hundred yuan, and it must be gold-plated.
3. If you find that the purchased gold ornaments are inconsistent with the online display or cause damage, you should refuse to sign for them and contact the seller in time.
4. The wearing effect of online gold jewelry is not intuitive, and it is not suitable to try it on. To buy a gold ring online, you need to measure the size first, and the length of the gold necklace should be measured.
