Regarding the difference between pure gold, karat gold, karat white gold, platinum, and platinum, To solve the mystery, we need to start with understanding the content and label of gold. In my country, pure gold was first advocated, but after the 1990s, with the popularity of gem-set jewelry, 18k gold jewelry became the mainstream of fashion jewelry. So what is pure gold? What is k gold? Pure gold refers to pure gold with a gold content of more than 99%. There are usually two pure gold (99%) and thousand pure gold (99.9%). K gold refers to the alloy of gold and other metal elements. To be precise, the K unit is a gold measurement unit that divides the gold content into 24 equal parts. That is to say, as long as it is marked by k, whether it is yellow or white, it refers to the content of gold; the highest k gold is 24k gold, which is pure gold, and 18k, 14k, 9k, and 18k are also common. The gold content in gold is 18/24u003d75%, which means that the gold content is 75%, and 14k is 14/24u003d58.3%, which means that the gold content is 58.3%; other k-gold content can also be calculated based on this. Therefore, when buying jewelry, as long as the logo shows '18k', '14k', etc., it means that it is gold, not platinum; in addition, people always think that k gold is 18k gold, which is a big mistake. It's very wrong. In addition to the word 'kSome illegal hawkers often use 9k gold (37.5% gold content) to pretend to be 18k gold, which is collectively referred to as'k gold' when selling, and the gold content is not indicated, and customers will be fooled if they are not careful! In addition to 24k gold, other metal elements contained in other karat gold are generally silver (ag), copper (cu), nickel (ni), palladium (pd), etc. The types and contents of the elements contained are different, which will lead to The color of the prepared k gold is different, including yellow, white, rose, etc., among them, if the white is 18k gold, it is generally called 18k white gold, which means '18k white gold', and its main component is still gold , Not platinum. The term'Platinum' was first used to mean platinum, because platinum attracted people's attention with its dazzling white color. However, as people add some whitening elements such as nickel or palladium when preparing k gold, it will turn the original yellow gold into white, making white gold (such as 18k white gold) appear on the market. There is also the'patent' of platinum. There was chaos in the market for a while. Some illegal merchants also took advantage of the traditional belief that platinum is platinum and called 18k platinum as'platinum' to pretend to be platinum to deceive consumers. How to distinguish between k gold and platinum? It's actually very simple. The main thing is to pay attention to the logo on the jewelry product: No matter what color the gold product is, it will indicate the words'au','g','k' and the content mark of the thousand-point system or the hundred-point system. Commonly used symbols are: : Thousand points system: au990 au999 g990 g999 g750 gold: 18k 18k white gold 14k 9k and other platinum products will have the words'pt' or'pt' and the content of the thousand points system, such as: pt990 pt950 pt900. Palladium is an alloy of metal palladium, which is also a platinum group element. It has the words'pd' or'pd' and the content mark on the thousand-point system, such as: pd900 pd950, etc. According to the requirements of national standards, the minimum content of the components indicated in the jewelry product label is required by: gold and alloy jewelry with a gold content of not less than 375‰; silver jewelry with a silver content of not less than 80%; palladium jewelry with palladium content Not less than 50%; platinum jewelry contains no less than 85% platinum. Too low content is not allowed to be marked. Some merchants have launched'pt090' products. In fact, the platinum content is only 9%. Most of the ingredients are not platinum. It is undesirable to deceive consumers in disguise. Previous: The popularity of colored gold Next: The design of gold jewelry
