Physical gold purchased from China gold or gold shops will have their own Peugeot. If it is discounted on the international exchange, it will be recognized by domestic standards, because the gold sold by Bank of Beijing is of international standards and will not be discounted. In other words, if you take the physical gold purchased by Bank of Beijing to any country in the world, it will be exchanged according to international standards. I suggest you go to Bank of Beijing to buy it.
To buy gold, we must first choose a reputable brand enterprise. Don't be greedy for cheap brands. The price of gold is relatively transparent, so beware of those that are obviously lower than the market price.
Secondly, when buying gold products, remember to ask for invoices, which is the core of protecting consumers' rights and interests;
Third, if in doubt, you can find it in time. The gold jewelry testing institutions under the national technical supervision department are located in major cities, which makes it easier to detect the composition of gold jewelry.
Fourth, choose to invest in gold products such as gold bars and nuggets, and choose regular merchants who promise to buy back, and the quality can be guaranteed.
The testing standards of gold products in China are very strict, and the supervision of regular merchants from raw material purchase to storage to processing and sales is generally standardized. The sales of investment gold bars of major brands and channels in China can generally be repurchased, but they must be damaged when repurchased, then sprayed with a musket, and the gold bars become "golden bumps", and then detected by gold detection equipment. If there is any problem, you will know.
Moreover, the production process of gold bars is actually relatively simple, and there will be no technical problems, but the gold jewelry process is more complicated. A few enterprises may dispute the fineness of gold on minor issues such as solder joints, but it is not a problem of adulteration, so consumers need not worry.
Professional appraisal institutions generally appraise gold and silver products in two ways, one is nondestructive testing, that is, physical methods such as spectroscopy do not cause any appearance impact on the products; The second is destructive test, which uses chemical methods to identify substances extracted from commercial slices. China requires 990‰ pure gold, 999‰ pure gold and even 999.9‰ high pure gold.
9999 gold must be identified by chemical methods, and the rest can be identified by physical methods. Because "there is no shortage of gold", no matter how high the purity is, gold bars and ornaments contain impurities. Therefore, as long as the gold content reaches the standard, the state does not clearly stipulate whether the impurities contain elements such as tungsten and iridium. It does not mean that gold bars containing elements such as tungsten and iridium are unqualified. The key depends on the final gold content.
Even if gold bars and ornaments contain tungsten and iridium with a density similar to that of gold, appraisal institutions can still conduct appraisal by professional chemical means, and it is not difficult to detect them.
Finally, it should be reminded that gold jewelry itself is a consumer product, not an investment product. Its price already includes processing, loss, consumption tax and other expenses. At the time of discount, all merchants will calculate the price of gold raw materials, and there will be losses in the process of repurchase, so we should invest carefully.
