Teach you how to calculate the gold content of K gold
One of the characteristics of gold is its softness, so it is difficult to inlay a variety of exquisite styles, especially when it is inlaid with pearls, precious stones and jadeites. Therefore, people add a small amount of silver, copper, zinc and other metals to the 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 made into various colors according to needs. There are various colors of K gold jewelry popular in the world. Everyone has yellow and white. When gold is mixed with 25% palladium or nickel, it will become white, and the main component that makes up it is gold. This is called white gold. At the current state of the art, it is not possible to extract pure gold materials with a purity of 100%. Therefore, the gold standard K indicating the pure gold content in the gold product is generally referred to as pure gold as 24K gold, but it is theoretically gold with a gold content of 100%, which does not actually exist. Therefore, in the national standard, the gold content of the merchant's gold jewelry should not use the "24K gold" non-standard standard method. Since the pure gold is 24K, that is, the theoretical gold content is 100%, 1K means that the gold product contains 1/24 of pure gold, about 4.16%. 18K gold represents 18/24 gold, which is 75% pure gold, and the rest are other materials such as silver or copper. As the saying goes, "Gold is not full of red", generally gold jewelry contains less than 1% of other metals. For the quality of gold products, the national standard has a very clear regulation, that is, each piece of gold jewelry sold by the merchant must be listed to indicate its gold content and weight. The weight of gold jewelry is always subject to the national legal unit of measurement. The gold content should use “K gold†(excluding 24K gold), “foot gold†(with gold content not less than 99%), “thousands of gold†(including gold content not less than 99.9%), and “1000 foot pure gold†or “ Pure gold" and the standard methods of "24K gold" and "9999" which do not exist in practice.
