Jewelry processing tricks of stealing gold under the nose

The price drop has removed the noble label from the gold jewelry, making it a part of ordinary people's daily consumption, and those gold jewelry processing shops with low fees have also increased their business. In fact, these processing shops that have not been approved by the relevant departments are often 'decreasing the price of the embankment, tearing off the noble label on the gold jewelry, making it a part of ordinary people's daily consumption, and the low-cost gold processing Shops have also gained a lot of business. In fact, these processing shops that have not been approved by the relevant departments are often'damages inside the embankment and compensation outside the embankment'. While attracting customers with low prices, they use various hidden methods to deceive customers. Steal gold. The following are several deceptions they often use: One of the deceptions: gold on the scales. At present, most of the gold weighing tools in jewelry processing shops are pallet balances. Some illegal gold jewelry processors use this type of pallet. The pallet of the balance is messed up. They deliberately made one pallet lighter and another heavy pallet. When they met someone using gold to process jewelry, they put the gold in the lighter pallet. After processing, they put the jewelry on the heavy. In the tray, even if you deduct a bit of the customer’s gold, you will be unconscious. The second trick: 'Aqua regia' peeling gold 'Aqua regia' is a mixture of concentrated nitric acid and concentrated hydrochloric acid in a molar ratio of 1:3 Although gold is a very stable substance, it is difficult to chemically react with other substances, but'aqua regia' can easily melt gold, so some illegal jewelry processors use this simple The chemical reaction cleans the gold jewelry for the customer, so that the customer will be stripped of the gold without being visible to the naked eye. Those processing shops that claim to be able to clean the gold jewelry for the customer for free often hide this kind of 'tricky'. Deception 3: Stealing gold for silver. Some illegal jewelry processors are smelting gold and processing jewelry for customers. They practice deception. In the process of smelting gold for customers, they mix some silver powder and copper powder with decontamination powder. In smelting with gold, what customers see on the surface is that the processor removes the impurities in the gold for them. In essence, they are adulterating the molten gold in the name of removing impurities. The main purpose is After deducting the customer's gold, it also makes the customer less likely to notice that the weight is reduced. Fool 4: Touching for gold in troubled waters, some deliberately leave a small part of gold in their plaster mold when processing jewelry, and in front of the customer Throwing away the waste plaster molds creates an illusion that there is no gold in the plaster molds. After the customers leave, they take back the discarded waste molds and take out the gold. There are also a small number of illegal jewelry processors who take advantage of the customers' attention. , Cut off some of the'leftovers' from the customer's jewelry and secretly take it as his own. In order to make up for the original weight of the customer's gold, fake'goods' are mixed in the smelting process. Fifth trick:'secondary' gold is generally good. Jewelry processing shops will sell finished gold jewelry, and most of these jewelry are processed by themselves. When processing, they deliberately mix fake'goods' into the gold, but when they sell it, they sell it as high-quality gold jewelry. Most of these jewelry have been steamed with sulfuric acid and generally look very bright. Those who do not know the 'goods' are easily deceived by the appearance of these jewelry and be fooled. As long as consumers take precautions in buying and processing jewelry, these frauds can be easily spotted by keeping their eyes open. However, I still want to remind consumers that when buying and processing gold jewelry, they should not be greedy for 'small profits'. It is best to go to larger jewelry processing shops approved by the People's Bank of China. Previous: The History of Gold Production in the United States Next: The Popularity of Colored Gold
