There was such a friend who saved money for a long time in order to buy a ring to give it to the people. However, he still couldn't afford the jewelry in the jewelry shop. He could only buy it with an acquaintance. After the small apartment of the "individual household", he showed many dazzling gold, silver and platinum jewelry. The 24 -carat label engraved on the gold ring made the friend feel the quality of the quality, so he believed that he had a stories about his uncle's jewelry shop and unexpected accumulation of jewelry. In the end, the friend decided to buy a ring and engraved with affection on it. His girlfriend also likes this ring very much. Everything looks so perfect. Until the next day she woke up, she found a circle of green ring on her fingers. It turned out that the friend was deceived, and the "individual household" introduced by the acquaintance sold fake gold jewelry.
This with green traces after wearing a gold ring indicates that this is definitely not real gold. When a customer buys gold ornaments, he or she will be informed of the purity of the gold jewelry, that is, the carat number of the gold jewelry, and the 14K or 18K engraved in the ring also means this. Gold is soft, so it is difficult to maintain a unique shape, and it can't stand it at night to wear it every day. Therefore, it will be mixed with other metals and refined into a relatively strong alloy. Metals for manufacturing alloys can be copper, tin, nickel, 钯, and so on. The highest level of 24 carat gold is the highest in purity and the most durable.
If you buy a very cheap fake gold ring, most of them are made of copper. When sweating, the salt generated by the acidic substances in the rings and the acidic substances in the sweat is green. These acidic substances mainly corrode the copper on the surface of the metal to form a metal salt mixture. After the skin absorbs these salts, it will form a clear green fingerprint. However, if it is not allergic to metal, there is no need to worry. This just shows that what you think is that the real gold ring is just a cheap imitation product. Metal allergies can cause redness and swelling, not green. Another method of identifying fake gold is to see if it will rust in a very humid environment or due to a long time.
