What does 9999 pure gold mean? Is there a difference between 9999 pure gold and 9999 pure gold?

Many people don’t know what 9999 pure gold means. In fact, the purity of gold on the market is indicated by numbers. The digital logo of gold represents its purity, and 9999 is 100% pure gold.

9999 pure gold means that the gold content is not less than 99.99%, which is called 100% pure gold. The digital mark of gold represents its purity. For example, 999 is 1000% pure gold, and the purity of gold is 999/1000, while 9999 is 100% pure gold, which is higher in purity, indicating that the purity of gold is 9990/10000, which is a difference of 9/10000.

There is a difference.

1. The difference between 9999 and 9999 gold is mainly the purity. 9999 gold has a gold content of 99.9% and 9999 has a gold content of 99.99%. However, if it is used for jewelry, because welding is required, 99.9% is the highest. Gold bars are generally 9999.

2. The difference between 1000-carat gold and 100-carat gold lies in its purity. The purity of gold products is called "purity" or "purity". The higher the purity of gold, the darker the color. Therefore, when we buy gold jewelry to judge the gold content, we can judge the gold purity based on the color of gold under strong light.

3. The difference between 999 gold and 1000-carat gold also lies in the softness and hardness of their texture. Anyone who has come into contact with gold jewelry knows that one characteristic of gold is that it is relatively soft. This characteristic of gold is also a criterion for identifying its authenticity.

4. 1000-carat gold is not pure gold. 1000-carat gold is just purer than 999-carat gold and has a higher gold content.

5. The digital mark of gold represents its purity. 999 means 999-carat gold, which means the purity of gold is 999/1000; 9999 means 9999-carat gold, which means the purity of gold is 9990/10000, which is a difference of 9/10000. Now the state stipulates that all gold jewelry must be marked with 999-carat gold or 1000-carat gold, which are collectively called pure gold.

6. The national standard only defines 999 pure gold, which means that 999 pure gold is the highest purity. Even if 9999 gold is sold, it cannot be detected when purchased. Therefore, we can only say that 9999 is a high-purity gold in theory, which is called "1000 pure gold" by the public in the market.

The difference between 9999 gold and 999 gold is the purity: 999 gold has a gold content of 99.9%, and 9999 gold has a gold content of 99.99%. The digital logo of gold represents its purity. 999 means 999 pure gold, and the purity of gold is 999/1000; 9999 means 9999 pure gold, which means the purity of gold is 9999/10000, which is a difference of 9/10000. 999 pure gold is more common in gold jewelry. Because gold is relatively soft, many gold jewelry need to add some non-gold materials to the joints, buckles and other parts to make the jewelry more solid during production. In this way, the overall purity will be reduced, and it is difficult to reach 9999 pure gold. Generally speaking, the purity of gold bars or some styles with simpler craftsmanship is 9999 pure gold. And from August 2017, the new national standard stipulates that 999 pure gold and 9999 pure gold will be collectively referred to as "pure gold", and the gold content of pure gold must be greater than or equal to 99%. Therefore, for gold jewelry, the difference between the two is not too big, and the impact on the later recycling of old gold is also small. There is no need to be too entangled in the difference between the two. In fact, for the jewelry we wear, 999 gold is enough. Whether in terms of color, purity, and craftsmanship, 999 gold has reached the highest level of jewelry. When making jewelry, because welding is required, 99.9% is generally the highest. Saying that jewelry is 9999 is fooling people. Gold bars are generally 9999. Now the state stipulates that all gold jewelry must be marked with 9999 gold or 10,000 gold, collectively referred to as pure gold.

Hard gold refers to physical gold, but it is "hard" gold made by a new method. Its texture is harder than ordinary gold. It is also called "thousand-foot hard gold". 0.005% is made of special metals added to it to increase its hardness, thus achieving the corresponding hardness. Hard gold is hardened by a special process, and becomes ordinary gold again after being exposed to fire. Because of the different process, the price will be more expensive.
