Do you have any friends who know about jewelry? Which is better, platinum or gold?

K gold (or gold) is an alloy formed by the fusion of gold and other metals. The "k" of K-gold is the compilation of the foreign word "Karat". The complete expression is gold opening (that is, k gold), and "AU" or "G" is an international symbol used to express the purity (that is, gold content) of gold.

K-gold jewelry is characterized by less gold consumption, low cost, can be made into various colors, improved hardness and is not easy to deform and wear. K gold is divided into 24K gold, 22K gold, 18K gold and 9K gold according to the gold content.

K gold can be made into various colors as needed. K-gold jewelry popular in the world has various colors, and the common ones are yellow and white. When 25% palladium or nickel is mixed with gold, it will turn white, and its main component is gold. This is called platinum.

As far as the level of science and technology is concerned, it is impossible to extract pure gold materials with the purity of 100% at present. Therefore, the gold standard K, which represents the pure gold content in gold products, generally calls pure gold 24K gold, but it only has a theoretical gold content of 100%, but it does not exist. Therefore, in the national standard, merchants are not allowed to use the nonstandard standard method of "24K gold" to mark the gold content of gold jewelry.
