According to the definition of national standard, gold is divided into the following categories, and the minimum purity per thousand is 375, 585, 750, 9 16, 990 and 999 respectively. Other expressions of the corresponding purity are: 9K, 14K, 18K, 22K, pure gold, and pure gold. For jewelry, the national standard only defines thousands of gold. At present, the purity of pure gold in China market is: "Sanjiu Gold", with a purity of 99.9%, commonly known as thousands of gold; "Erjiu Gold", with a purity of 99%, is commonly known as pure gold. Wanjinjin adopts the advanced technology of "9999 (Safir) gold welding process" and pays tribute to the supreme gold products with 99.99% purity. Thousands of gold is purer than thousands of gold, and thousands of gold exceeds the national jewelry standards. Not only the product quality reaches 99.99%, but also the overall uniformity of gold jewelry quality reaches 100%, which solves the industry problem of low quality of gold jewelry solder joints and meets the consumer's demand for perfection and purity.

Some authoritative experts said that "thousands of gold" is the national standard, while "ten thousand gold" is only the propaganda tone or advertising words of merchants, and does not necessarily represent the gold content. There is no such thing as "universal oil" in the national standard. The national standard is three nines, only gold bars have three nines and four nines. Even if the consumer's shopping receipt clearly says "ten thousand gold", it can't pass the quality inspection certificate, because according to the national regulations on the naming of precious metals, "ten thousand gold" is the highest purity in the national standard for the color of gold jewelry, and there is no relevant regulation on "ten thousand gold" in the standard. Moreover, with the accuracy of the existing instruments, even if the purity of gold jewelry does reach 99.99%, the general testing institutions can't detect it.

In fact, "ten thousand gold" is actually a loophole in the national standard. The so-called "ten thousand gold" has become a concept and has no practical significance. "Tiger balm" is not a national standard, but an enterprise standard. The expression of "ten thousand gold" is actually a means of promotion for merchants, using the common sense that the purer the gold, the better to attract consumers to buy. However, because the price of "ten thousand gold" is higher than that of "thousands of gold", merchants can gain more profit space in this way. It is inevitable that some unscrupulous merchants will take advantage of the loopholes and label gold ornaments with a color less than four nines as "ten thousand gold" in order to obtain higher profits.

Matters needing attention

Wanjinjin ornaments

1, avoid wearing gold ornaments, especially rings, when doing heavy work.

2. Because of the low hardness of gold jewelry, you should handle it carefully when wearing it to avoid collision and friction with hard objects. No pulling, pulling or dragging. Diamonds, in particular, have different hardness, so they will be scratched when rubbed against each other, so they should be stored separately in jewelry boxes.

3. Don't store gold ornaments and silver ornaments together, so as not to collide with each other and make the surface of gold ornaments turn silver. When the gold ring and platinum ring are worn together, it is easy for them to rub against each other, which makes the surface of the gold ring locally white and platinum.

4. It is normal for gold jewelry to lose its luster gradually due to factors such as sweating for a long time. In this case, the customer needs to return the jewelry to the jewelry store for cleaning.

5. Mercury corrodes the surface of gold, and high-grade cosmetics often contain a small amount of lead and mercury. If gold jewelry often contacts cosmetics for a long time, white spots will appear on the surface of the jewelry. Therefore, when wearing gold jewelry, try to avoid contact with cosmetics. If this happens, go to a professional jewelry store to deal with it, and the white spots will be removed. Also avoid contact with vegetable juices containing chemical elements, such as mustard juice, cauliflower juice and fish scales.
