Answer: Yes, 24k gold is pure gold, and its theoretical content reaches 100%. But in fact, jewelry with a gold content of 100% is impossible. So as long as the gold content reaches more than 99.6%, it can be called 24k gold, which is pure gold.

As we know, the content of pure gold in decorative gold is called "golden position", which is Karat in English, so it is called K gold. Generally speaking, pure gold is called 24K, which means the theoretical gold content is 100%. In addition, we often have 22k gold, 18k gold, 14k gold and so on. In China, 18K is generally used for inlaying jewelry, so the fastness of inlaying jewelry is relatively high.
