How to calculate the gold content of K gold

One of the characteristics of gold is its softness, so it is difficult to inlay various exquisite styles, especially when inlaid with treasures such as pearls, gems and jadeites, it is easy to be lost. Therefore, people add a small amount of silver, copper, zinc and other metals to gold to increase the strength and toughness of gold. One of the characteristics of gold is soft, so it is difficult to inlay various exquisite styles, especially It is easy to be lost when inlaid with treasures such as pearls, gems and jade. Therefore, people add a small amount of silver, copper, zinc and other metals to gold to increase the strength and toughness of gold. The gold ornaments made in this way are also called k gold. K gold can be prepared into various colors according to needs. The popular K gold jewelry in the world has various colors, and the common ones are yellow and white. If 25% of palladium or nickel is mixed into gold, it will become white. The main component of it is still gold, which is called white k gold. As far as the current level of technology is concerned, it is still impossible to extract pure gold materials with a purity of 100%. Therefore, the gold level standard k that indicates the content of pure gold in gold products generally refers to pure gold as 24k gold, but it is gold with 100% gold in theory, and does not actually exist. Therefore, in the national standard, merchants must not use the non-standard method of '24k gold' to indicate the gold content of gold jewelry. Since pure gold is called 24k, that is, the theoretical gold content is 100%, 1k means that gold products contain 1/24 of pure gold, which is about 4.16%. 18k gold means that the gold content is 18/24, which is 75% pure gold, and the rest is other materials such as silver or copper. As the saying goes,'gold is not pure'. Generally, gold jewelry contains less than 1% of other metals. Regarding the fineness of gold content in gold products, the national standard has very clear regulations, that is, each piece of gold jewelry sold by merchants must be listed with its gold content and weight. The weight of gold jewelry will always use the national legal unit of measurement. Its gold content should use'k gold' (excluding 24k gold),'full gold' (gold content not less than 99%),'thousand pure gold' (gold content not less than 99.9%), and'thousand pure gold','cannot be used' Non-standard standard methods such as pure gold and non-existent 24k gold and 9999.
