Don't care too much. Now all gold and silver jewelry will contain alloy components. I suggest not to call directly. You'd better find a gold shop, such as Chow Tai Fook. They will add some processing fees, but the quality can be guaranteed. However, try not to hit directly. There will be quality problems
four tricks:
1. The trick of deducting gold on the scale is the most common trick used by a few bad enterprises. At present, most gold weighing tools in gold jewelry processing shops are pallet scales. Those bad merchants use this pallet scale to make the weight of the two pallets different. When someone takes gold jewelry into the store for processing, he puts the gold in a light tray. After processing, he puts the jewelry on a heavy tray. In this way, even if you deduct a small amount of gold from the customer, you will not know. Therefore, we should re weigh before and after jewelry processing to avoid being deceived
2. To remove the dirt on the surface of gold jewelry, it is necessary to immerse the gold jewelry in low concentration hydrochloric acid solution. However, some illegal traders added nitric acid to the hydrochloric acid solution used when cleaning gold jewelry. This mixture of hydrochloric acid and nitric acid is the so-called "Royal water", which is highly corrosive to gold and can dissolve gold. As long as the gold after high-temperature roasting is immersed in "aqua regia" for 20 minutes, the gold can be dissolved and released. Adding active metals to the "aqua regia" containing gold can reduce gold, and consumers' gold is "stolen" by unscrupulous merchants unconsciously
3. Some gold jewelry processing shops sell finished gold jewelry. Most of these gold jewelry are processed by merchants themselves. During the processing, they deliberately mixed other impurities in the gold to reduce the purity of the gold. Then they boil the gold jewelry with sulfuric acid to make it look bright, and then sell it at the price of high-quality gold jewelry. Some unknown consumers will be deceived by the appearance of these gold jewelry
4. This kind of scam is that some illegal traders use the process of smelting gold for their customers to mix some impurities of silver powder and copper powder and smelt them together with gold. On the surface, what we see is to help customers remove impurities in gold. In fact, it is taking the opportunity to steal some customers' gold. The purpose of doping silver or copper powder is to keep the weight of jewelry, but in fact, the processed gold jewelry has lost its original purity
It's not recommended to go to a small processing shop. Even if you look around, there may be adulteration
if you want to process, it is recommended to go to a good processing shop in advance to avoid falling into the pit. For example, in a brand gold store, there is a small counter where gold is played. You can go there to play gold. You can feel more at ease. The price is also higher than that of the brand store
extended data:
gold is the elemental form of the chemical element gold (AU), which is a soft, golden yellow, corrosion-resistant precious metal. Gold is one of the rare, precious and highly valued metals. In the world, gold is generally measured in ounces. In ancient China, the unit of gold was "Liang", which is a very important metal. It is not only a special currency for reserve and investment, but also an important material for jewelry industry, electronics industry, modern communications, aerospace industry and other sectors
the chemical symbol of gold is Au, and the financial English code is XAU or gold. The name of Au comes from a story of Aurora, the goddess of dawn in Roman mythology, which means shining dawn
as of October 12, 2021, the gold price was US $1760 / oz
market status:
according to the statistical data recently released by the China Gold Association, in the first half of 2015, the national gold output reached 228.735 tons, an increase of 17.662 tons over the same period of 2014, an increase of 8.37% over the same period of 2014. Among them, 191.689 tons of gold mineral gold and 37.046 tons of non-ferrous by-product gold were completed
at the same time, China's gold consumption has declined. In the first half of 2015, the national gold consumption was 561.35 tons, a decrease of 8.10 tons or 1.42% compared with the same period in 2014. Among them, 412.29 tons of gold were used for jewelry manufacturing, a year-on-year decrease of 3.26%, 102.13 tons of gold bars and gold coins, and 46.93 tons of industrial and other gold
according to the analysis report on China's gold industry market prospect and investment strategic planning, from April 2013 to the middle of 2015, the international gold price has been in a downturn after a sharp decline. From the perspective of the global economic situation, the world economic growth rate may pick up slightly in 2015, but it is difficult to make a significant improvement in the overall weak recovery. The volatility of the international financial market and the commodity market has increased, and geopolitical and other non economic factors have a great impact. There are still many uncertain factors. With the strengthening of the US dollar, the prices of gold, non-ferrous metals, oil and other bulk commodities were low in 2015. The low price of gold in the next few years may become a "new normal"
on August 1, 2019, a report released by the World Gold Council on August 1 showed that in the first half of 2019, the global demand for gold increased by 8% year-on-year to 2181.7 tons, which was the highest in the same period in the past three years.
Hehe, don't worry too much about this. Now all gold and silver jewelry contains alloy components. It is recommended that you don't hit it directly. You'd better find a gold shop, such as Chow Tai Fook, and then replace it. They will add a processing fee to it. However, the quality can be guaranteed, but try not to hit it directly. There will be problems with the quality.
Small processing shops definitely don't recommend beating. Even if you watch him beat with your eyes wide open, you will still be stolen after weighing
if you must, go to a regular processing shop. However, it takes some time to find this kind of shop. Now there are fewer such shops
for example, in a brand gold store, there is a small counter where gold is played. You can go there to play gold. You can feel more at ease. The price is also higher than that of the brand store
